# Adopters
Known end users with notable contributions to the project include:
* AWS
* IBM
* Red Hat
Falco is being used by numerous other companies, both large and small, to build higher layer products and services. The list includes but is not limited to:
* Equinix Metal
* IEEE
* Lowes
* Reckrut
* Yellow Pepper
* CTx
* Utikal
* Discrete Events
* Agritech Infra
This is a list of production adopters of Falco (in alphabetical order):
* [ASAPP](https://www.asapp.com/) - ASAPP is a pushing the boundaries of fundamental artificial intelligence research. We apply our research into AI-Native® products that make organizations, in the customer experience industry, highly productive, efficient, and effective—by augmenting human activity and automating workflows. We constantly monitor our workloads against different hazards and FALCO helps us extend our threat monitoring boundaries.
* [Booz Allen Hamilton](https://www.boozallen.com/) - BAH leverages Falco as part of their Kubernetes environment to verify that work loads behave as they did in their CD DevSecOps pipelines. BAH offers a solution to internal developers to easily build DevSecOps pipelines for projects. This makes it easy for developers to incorporate Security principles early on in the development cycle. In production, Falco is used to verify that the code the developer ships does not violate any of the production security requirements. BAH [are speaking at Kubecon NA 2019](https://kccncna19.sched.com/event/UaWr/building-reusable-devsecops-pipelines-on-a-secure-kubernetes-platform-steven-terrana-booz-allen-hamilton-michael-ducy-sysdig) on their use of Falco.
* [Coveo](https://www.coveo.com/) - Coveo stitches together content and data, learning from every interaction, to tailor every experience using AI to drive growth, satisfy customers and develop employee proficiency. All Falco events are centralized in our SIEM for analysis. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions with containers and orchestration systems. Falco is giving us a good visibility inside containers and complement other Host and Network Intrusion Detection Systems. In a near future, we expect to deploy serverless functions to take action when Falco identifies patterns worth taking action for.
* [Deckhouse](https://deckhouse.io/) - Deckhouse Platform presents to you the opportunity to create homogeneous Kubernetes clusters anywhere and handles comprehensive, automagical management for them. It supplies all the add-ons you need for auto-scaling, observability, security, and service mesh. Falco is used as a part of the [runtime-audit-engine](https://deckhouse.io/documentation/latest/modules/650-runtime-audit-engine/) module to provide threats detection and enforce security compliance out of the box. By pairing with [shell-operator](https://github.com/flant/shell-operator) Falco can be configured by Kubernetes Custom Resources.
* [Fairwinds](https://fairwinds.com/) - [Fairwinds Insights](https://fairwinds.com/insights), Kubernetes governance software, integrates Falco to offer a single pane of glass view into potential security incidents. Insights adds out-of-the-box integrations and rules filter to reduce alert fatigue and improve security response. The platform adds security prevention, detection, and response capabilities to your existing Kubernetes infrastructure. Security and DevOps teams benefit from a centralized view of container security vulnerability scanning and runtime container security.
* [Frame.io](https://frame.io/) - Frame.io is a cloud-based (SaaS) video review and collaboration platform that enables users to securely upload source media, work-in-progress edits, dailies, and more into private workspaces where they can invite their team and clients to collaborate on projects. Understanding what is running on production servers, and the context around why things are running is even more tricky now that we have further abstractions like Docker and Kubernetes. To get this needed visibility into our system, we rely on Falco. Falco's ability to collect raw system calls such as open, connect, exec, along with their arguments offer key insights on what is happening on the production system and became the foundation of our intrusion detection and alerting system.
* [Giant Swarm](https://www.giantswarm.io/) - Giant Swarm manages Kubernetes clusters and infrastructure for enterprises across multiple cloud providers as well as several flavors of on-premises data centers. Our platform provisions and monitors pure "vanilla" Kubernetes clusters which can be augmented with managed solutions to many common Kubernetes challenges, including security. We use Falco for anomaly detection as part of our collection of entirely open-source tools for securing our own clusters, and offer the same capabilities to our customers as part of our [managed security offering](https://docs.giantswarm.io/app-platform/apps/security/).
* [GitLab](https://about.gitlab.com/direction/defend/container_host_security/) - GitLab is a complete DevOps platform, delivered as a single application, fundamentally changing the way Development, Security, and Ops teams collaborate. GitLab Ultimate provides the single tool teams need to find, triage, and fix vulnerabilities in applications, services, and cloud-native environments enabling them to manage their risk. This provides them with repeatable, defensible processes that automate security and compliance policies. GitLab includes a tight integration with Falco, allowing users to defend their containerized applications from attacks while running in production.
* [gVisor](https://gvisor.dev/) - gVisor secures Kubernetes, containers, and workloads via an alternate execution environment that handles system calls in user space, blocking security issues before they reach the underlying host. gVisor provides defense-in-depth, protection against untrusted code execution, and a secure-by-default Kubernetes experience where containers are a security boundary. Falco can be used with gVisor to detect unusual or suspicious activity using its threat detection engine on top of gVisor runtime execution information.
* [League](https://league.com/ca/) - League provides health benefits management services to help employees understand and get the most from their benefits, and employers to provide effective, efficient plans. Falco is used to monitor our deployed services on Kubernetes, protecting against malicious access to containers which could lead to leaks of PHI or other sensitive data. The Falco alerts are logged in Stackdriver for grouping and further analysis. In the future, we're hoping for integrations with Prometheus and AlertManager as well.
* [Logz.io](https://logz.io/) - Logz.io is a cloud observability platform for modern engineering teams. The Logz.io platform consists of three products — Log Management, Infrastructure Monitoring, and Cloud SIEM — that work together to unify the jobs of monitoring, troubleshooting, and security. We empower engineers to deliver better software by offering the world's most popular open source observability tools — the ELK Stack, Grafana, and Jaeger — in a single, easy to use, and powerful platform purpose-built for monitoring distributed cloud environments. Cloud SIEM supports data from multiple sources, including Falco's alerts, and offers useful rules and dashboards content to visualize and manage incidents across your systems in a unified UI.
* https://logz.io/blog/k8s-security-with-falco-and-cloud-siem/

## Code of Conduct
Falco has a
[Code of Conduct](CODE_OF_CONDUCT)
to which all contributors must adhere, please read it before interacting with the repository or the community in any way.
## Issues
Issues are the heartbeat ❤️ of the Falco project, there are mainly three kinds of issues you can open:
- Bug report: you believe you found a problem in Falco and you want to discuss and get it fixed,
creating an issue with the **bug report template** is the best way to do so.
- Enhancement: any kind of new feature need to be discussed in this kind of issue, do you want a new rule or a new feature? This is the kind of issue you want to open. Be very good at explaining your intent, it's always important that others can understand what you mean in order to discuss, be open and collaborative in letting others help you getting this done!
- Failing tests: you noticed a flaky test or a problem with a build? This is the kind of issue to triage that!
The best way to get **involved** in the project is through issues, you can help in many ways:
- Issues triaging: participating in the discussion and adding details to open issues is always a good thing,
sometimes issues need to be verified, you could be the one writing a test case to fix a bug!
- Helping to resolve the issue: you can help in getting it fixed in many ways, more often by opening a pull request.
### Triage issues
We need help in categorizing issues. Thus any help is welcome!
When you triage an issue, you:
* assess whether it has merit or not
* quickly close it by correctly answering a question
* point the reporter to a resource or documentation answering the issue
* tag it via labels, projects, or milestones
* take ownership submitting a PR for it, in case you want 😇
#### More about labels
These guidelines are not set in stone and are subject to change.
Anyway a `kind/*` label for any issue is mandatory.
This is the current [label set](https://github.com/falcosecurity/falco/labels) we have.
You can use commands - eg., `/label <some-label>` to add (or remove) labels or manually do it.
The commands available are the following ones:
```
/[remove-](area|kind|priority|triage|label)
```
Some examples:
* `/area rules`
* `/remove-area rules`
* `/kind kernel-module`
* `/label good-first-issue`
* `/triage duplicate`
* `/triage unresolved`
* `/triage not-reproducible`
* `/triage support`
* ...
### Slack
Other discussion, and **support requests** should go through the `#falco` channel in the Sysdig slack, please join [here](https://slack.sysdig.com).
## Pull Requests
Thanks for taking time to make a [pull request](https://help.github.com/articles/about-pull-requests) (hereafter PR).
In the PR body, feel free to add an area label if appropriate by typing `/area <AREA>`, PRs will also
need a kind, make sure to specify the appropriate one by typing `/kind <KIND>`.
The list of labels is [here](https://github.com/falcosecurity/falco/labels).
Also feel free to suggest a reviewer with `/assign @theirname`.
Once your reviewer is happy, they will say `/lgtm` which will apply the
`lgtm` label, and will apply the `approved` label if they are an
[owner](/OWNERS).
Your PR will be automatically merged once it has the `lgtm` and `approved`
labels, does not have any `do-not-merge/*` labels, and all status checks (eg., rebase, tests, DCO) are positive.
## Developer Certificate Of Origin
The [Developer Certificate of Origin (DCO)](https://developercertificate.org/) is a lightweight way for contributors to certify that they wrote or otherwise have the right to submit the code they are contributing to the project.
Contributors to the Falco project sign-off that they adhere to these requirements by adding a `Signed-off-by` line to commit messages.
```
This is my commit message
Signed-off-by: John Poiana <jpoiana@falco.org>
```
Git even has a `-s` command line option to append this automatically to your commit message:
```
$ git commit -s -m 'This is my commit message'
```

# How to contribute
## Enforce coding style 💻
### Introduction
This document introduces the coding style that will be applied in this repository.
This coding style involves all the following files: `.c`, `.h`, `.cpp`, `.cmake`, `CMakeLists.txt`. To enforce it we rely on two main tools:
1. `clang-format` version `18.1.8`.
2. `cmake-format` version `0.6.13`.
> __Please note__: tools versions are important! Different versions will enforce slightly different changes on the code. For example `clang-format-18` will produce a slightly different output respect to `clang-format-17` always respecting the imposed style.
The coding style is expressed through the 2 configuration file that you find in this repo: `.clang-format`, `.cmake-format.json`.
### Enforce the style locally
There are many ways to enforce the style locally, here we will describe two of them:
1. Use `pre-commit` framework.
2. Use the repo `Makefile`.
#### 1.Pre-commit framework (suggested if you don't have the 2 tools already installed on your machine)
The `pre-commit` framework allows you to automatically install different `git-hooks` that will run at every new commit. More precisely, if you use the `.pre-commit-config.yaml` in this repo you will install 3 different hooks:
1. The `clang-format` hook: this is a `pre-commit` git hook that runs `clang-format` on your staged changes.
2. The `cmake-format` hook: this is a `pre-commit` git hook that runs `cmake-format` on your staged changes.
3. The `DCO signed-off` hook: this is a `pre-commit-msg` git hook that adds the `DCO` on your commit if not present. This hook is not strictly related to the coding style so we will talk about it in a separate section: [Add DCO signed-off to your commits](#add-dco-signed-off-to-your-commits).
Now let's see what we need to use `pre-commit` framework.
##### Step 1
Install `pre-commit` framework following the [official documentation](https://pre-commit.com/#installation).
> __Please note__: you have to follow only the "Installation" section.
##### Step 2
Once you have installed `pre-commit`, you don't need to install anything else! This is the good point of using a framework like `pre-commit`, all the tools necessary to format your code will be directly managed by the framework. But in order to be ready, you need to install the git hooks in your local repo.
This simple command allows you to install the two `pre-commit` git hooks, `clang-format` and `cmake-format`.
```bash
pre-commit install --install-hooks --hook-type pre-commit --overwrite
```
If you want to install also the `pre-commit-msg` git hook for the DCO you have to type the following command, but be sure to have configured all you need as said in the [dedicated section]((#add-dco-signed-off-to-your-commits))
```bash
pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite
```
You have done, at every new commit, this hook will check that your patch respects the coding style of this repo!
If you want to detach the git hooks, you can simply type:
```bash
pre-commit uninstall --hook-type prepare-commit-msg
pre-commit uninstall --hook-type pre-commit
```
#### 2.Makefile
##### Step 1
In order to use the repo `Makefile`, you need to install on your local machine the two aforementioned tools:
__clang-format v18.1.8__
One of the easiest ways to install `clang-format` could be directly downloading its static binary from [here](https://github.com/muttleyxd/clang-tools-static-binaries).
There are other ways for example you can download the package for your distro or you can also build it from sources.
__cmake-format v0.6.13__
To install `cmake-format` you can follow the official documentation [here](https://cmake-format.readthedocs.io/en/latest/installation.html).
> __NOTE__: Please check the versions of the two tool with `clang-format --version` and `cmake-format --version`.
##### Step 2
Once you have installed the __right__ versions of the 2 tools, you can simply type `make format-all` from the root directory of the project (`/libs`) to format all your code according to the coding style.
Remember to do that before submitting a new patch upstream! 😁
#### Other solutions
Obviously, you can also install the 2 tools locally and enable some extension of your favorite IDE (like `VScode`) to format your code every time you save your files!
## Add DCO signed-off to your commits 🔏
### Introduction
Another requirement for contributing to the `libs` repository, is applying the [DCO](https://cert-manager.io/docs/contributing/sign-off/) to every commit you want to push upstream.
Before doing this you have to configure your git user `name` and `email` if you haven't already done it. To check your actual `name` and `email` type:
```bash
git config --get user.name
git config --get user.email
```
If they are correct you have done, otherwise, you have to set them:
```bash
git config user.name <full-name>
git config user.email <mail-used_with-GitHub-profile>
```
>__Please note__: If you have problems in doing this you can read the full documentation [here](https://docs.github.com/en/get-started/getting-started-with-git/setting-your-username-in-git).
### Enforce the DCO locally
Now you are ready to sign your commits! You have two main ways to do this:
1. Manually with `git` tool.
2. Use the `pre-commit-msg` hook quoted before.
### Manually
To do this you just need to remember the `-s` while performing your commits:
```bash
git commit -s
```
or with the inline message:
```bash
git commit -s -m "my first commit"
```
### Use `pre-commit` hook
Here if you have already added the hook in the [previous section](#step-2), you have to do nothing otherwise you have to simply install the DCO hook with:
```bash
pre-commit install --install-hooks --hook-type prepare-commit-msg --overwrite
```
And you have done! Now you don't have to remember the `-s` option every time you commit something, the DCO hook will automatically add the DCO if you forget it! 😄
## Some best practices 📏
### Class variables
To know whether a variable belongs to a `class` or a `function`, we start member variables with `m_`.
Example:
```c
public int32_t m_counter;
```
### Global variables
To know whether the variable is global or not, we start globals with `g_`.
Example:
```c
int g_nplugins;
```
### Capitalization
The naming convention is camel-cased "Unix" style, i.e. always lower case. Words are separated by underscores.
Example:
```c
int32_t g_global_bean_counter;
int32_t count_beans();
```
and not,
```c
int32_t GlobalBeanCounter;
int32_t CountBeans();
```
### Packed Structures
Packed structures should use the GCC and MSVC-style supported `pragma`:
Example:
```c
#pragma pack(push,1)
struct frame_control
{
struct fields....
};
#pragma pack(pop)
```
### 64-bit constants
Put an `LL` at the end of your `64-bit` constants. Without the `LL`, some platform compilers try to interpret the constant on the right-hand side as a `long integer` instead of a `long long` and this could lead to an error at building time.
Example:
```c
x=0X00FF00000000000LL
```

# Process for becoming a maintainer
* Express interest to the existing maintainers that you or your organization is interested in becoming a
maintainer. Becoming a maintainer generally means that you are going to be spending substantial
time (>25%) on Falco for the foreseeable future. You should have domain expertise and be extremely
proficient in C++. Ultimately your goal is to become a maintainer that will represent your
organization.
* We will expect you to start contributing increasingly complicated PRs, under the guidance
of the existing maintainers.
* We may ask you to do some PRs from our backlog.
* As you gain experience with the code base and our standards, we will ask you to do code reviews
for incoming PRs (i.e., all maintainers are expected to shoulder a proportional share of
community reviews).
* After a period of approximately 2-3 months of working together and making sure we see eye to eye,
the existing maintainers will confer and decide whether to grant maintainer status or not.
We make no guarantees on the length of time this will take, but 2-3 months is the approximate
goal.
## Maintainer responsibilities
* Monitor Slack (delayed response is perfectly acceptable).
* Triage GitHub issues and perform pull request reviews for other maintainers and the community.
* During GitHub issue triage, apply all applicable [labels](https://github.com/falcosecurity/falco/labels)
to each new issue. Labels are extremely useful for future issue follow up. Which labels to apply
is somewhat subjective so just use your best judgment.
* Make sure that ongoing PRs are moving forward at the right pace or closing them.
* Participate when called upon in the security releases. Note that although this should be a rare
occurrence, if a serious vulnerability is found, the process may take up to several full days of
work to implement. This reality should be taken into account when discussing time commitment
obligations with employers.
* In general continue to be willing to spend at least 25% of ones time working on Falco (~1.25
business days per week).
## When does a maintainer lose maintainer status
If a maintainer is no longer interested or cannot perform the maintainer duties listed above, they
should volunteer to be moved to emeritus status. In extreme cases this can also occur by a vote of
the maintainers per the voting process below.
# Conflict resolution and voting
In general, we prefer that technical issues and maintainer membership are amicably worked out
between the persons involved. If a dispute cannot be decided independently, the maintainers can be
called in to decide an issue. If the maintainers themselves cannot decide an issue, the issue will
be resolved by voting. The voting process is a simple majority in which each senior maintainer
receives two votes and each normal maintainer receives one vote.
# Adding new projects to the falcosecurity GitHub organization
New projects will be added to the falcosecurity organization via GitHub issue discussion in one of the
existing projects in the organization. Once sufficient discussion has taken place (~3-5 business
days but depending on the volume of conversation), the maintainers of *the project where the issue
was opened* (since different projects in the organization may have different maintainers) will
decide whether the new project should be added. See the section above on voting if the maintainers
cannot easily decide.

[Falco](https://falco.org/) is a cloud native runtime security tool for Linux operating systems. It is designed to detect and alert on abnormal behavior and potential security threats in real-time.
---
At its core, Falco is a kernel monitoring and detection agent that observes events, such as syscalls, based on custom rules. Falco can enhance these events by integrating metadata from the container runtime and Kubernetes. The collected events can be analyzed off-host in SIEM or data lake systems.
Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Powered by [sysdigs](https://github.com/draios/sysdig) system call capture infrastructure, Falco lets you continuously monitor and detect container, application, host, and network activity—all in one place—from one source of data, with one set of rules.
Falco, originally created by [Sysdig](https://sysdig.com), is a **graduated project** under the [Cloud Native Computing Foundation](https://cncf.io) (CNCF) used in production by various [organisations](https://github.com/falcosecurity/falco/blob/master/ADOPTERS.md).
Falco is hosted by the Cloud Native Computing Foundation (CNCF) as a sandbox level project. If you are an organization that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details read the [Falco CNCF project proposal](https://github.com/cncf/toc/tree/master/proposals/falco.adoc).
For detailed technical information and insights into the cyber threats that Falco can detect, visit the official [Falco](https://falco.org/) website.
#### What kind of behaviors can Falco detect?
For comprehensive information on the latest updates and changes to the project, please refer to the [Change Log](CHANGELOG.md).
Falco can detect and alert on any behavior that involves making Linux system calls. Falco alerts can be triggered by the use of specific system calls, their arguments, and by properties of the calling process. For example, Falco can easily detect incidents including but not limited to:
## The Falco Project
The Falco Project codebase is maintained under the [falcosecurity GitHub organization](https://github.com/falcosecurity). The primary repository, [falcosecurity/falco](https://github.com/falcosecurity/falco), holds the source code for the Falco binary, while other sub-projects are hosted in dedicated repositories. This approach of isolating components into specialized repositories enhances modularity and focused development. Notable [core repositories](https://github.com/falcosecurity/evolution?tab=readme-ov-file#core) include:
- [falcosecurity/libs](https://github.com/falcosecurity/libs): This repository hosts Falco's core libraries, which constitute the majority of the binarys source code and provide essential features, such as kernel drivers.
- [falcosecurity/rules](https://github.com/falcosecurity/rules): It contains the official ruleset for Falco, offering pre-defined detection rules for various security threats and abnormal behaviors.
- [falcosecurity/plugins](https://github.com/falcosecurity/plugins): This repository supports integration with external services through plugins that extend Falco's capabilities beyond syscalls and container events, with plans for evolving specialized functionalities in future releases.
- [falcosecurity/falcoctl](https://github.com/falcosecurity/falcoctl): A command-line utility designed for managing and interacting with Falco.
- [falcosecurity/charts](https://github.com/falcosecurity/charts): This repository provides Helm charts for deploying Falco and its ecosystem, simplifying the installation and management process.
For further insights into our repositories and additional details about our governance model, please visit the official hub of The Falco Project: [falcosecurity/evolution](https://github.com/falcosecurity/evolution).
## Getting Started with Falco
If you're new to Falco, begin your journey with our [Getting Started](https://falco.org/docs/getting-started/) guide. For production deployments, please refer to our comprehensive [Setup](https://falco.org/docs/setup/) documentation.
As final recommendations before deploying Falco, verify environment compatibility, define your detection goals, optimize performance, choose the appropriate build, and plan for SIEM or data lake integration to ensure effective incident response.
### Demo Environment
A demo environment is provided via a docker-compose file that can be started on a docker host which includes falco, falcosidekick, falcosidekick-ui and its required redis database. For more information see the [docker-compose section](docker/docker-compose/)

## Building
For comprehensive, step-by-step instructions on building Falco from source, please refer to the [official documentation](https://falco.org/docs/developer-guide/source/).
## Testing
<details>
<summary>Expand Testing Instructions</summary>
Falco's [Build Falco from source](https://falco.org/docs/developer-guide/source/) is the go-to resource to understand how to build Falco from source. In addition, the [falcosecurity/libs](https://github.com/falcosecurity/libs) repository offers additional valuable information about tests and debugging of Falco's underlying libraries and kernel drivers.
Here's an example of a `cmake` command that will enable everything you need for all unit tests of this repository:
```bash
cmake \
-DUSE_BUNDLED_DEPS=ON \
-DBUILD_LIBSCAP_GVISOR=ON \
-DBUILD_BPF=ON \
-DBUILD_DRIVER=ON \
-DBUILD_FALCO_MODERN_BPF=ON \
-DCREATE_TEST_TARGETS=ON \
-DBUILD_FALCO_UNIT_TESTS=ON ..;
```
Build and run the unit test suite:
```bash
nproc=$(grep processor /proc/cpuinfo | tail -n 1 | awk '{print $3}');
make -j$(($nproc-1)) falco_unit_tests;
# Run the tests
sudo ./unit_tests/falco_unit_tests;
```
Optionally, build the driver of your choice and test run the Falco binary to perform manual tests.
Lastly, The Falco Project has moved its Falco regression tests to [falcosecurity/testing](https://github.com/falcosecurity/testing).
- A shell is running inside a container.
- A container is running in privileged mode, or is mounting a sensitive path, such as `/proc`, from the host.
- A server process is spawning a child process of an unexpected type.
- Unexpected read of a sensitive file, such as `/etc/shadow`.
- A non-device file is written to `/dev`.
- A standard system binary, such as `ls`, is making an outbound network connection.

1. The first lines of code at the base of Falco were written some time ago, where Go didn't yet have the same level of maturity and adoption as today.
2. The Falco execution model is sequential and mono-thread due to the statefulness requirements of the tool, and so most of the concurrency-related selling points of the Go runtime would not be leveraged at all.
3. The Falco code deals with very low-level programming in many places (e.g. some headers are shared with the eBPF probe and the Kernel module), and we all know that interfacing Go with C is possible but brings tons of complexity and tradeoffs to the table.
4. As a security tool meant to consume a crazy high throughput of events per second, Falco needs to squeeze performance in all hot paths at runtime and requires deep control on memory allocation, which the Go runtime can't provide (there's also garbage collection involved).
5. Although Go didn't suit the engineering requirements of the core of Falco, we still thought that it could be a good candidate for writing Falco extensions through the plugin system. This is the main reason we gave special attention and high priority to the development of the plugin-sdk-go.
6. Go is not a requirement for having statically-linked binaries. In fact, we provide fully-static Falco builds since few years. The only issue with those is that the plugin system can't be supported with the current dynamic library model we currently have.
7. The plugin system has been envisioned to support multiple languages, so on our end maintaining a C-compatible codebase is the best strategy to ensure maximum cross-language compatibility.
8. In general, plugins have GLIBC requirements/dependencies because they have low-level C bindings required for dynamic loading. A potential solution for the future could be to also support plugin to be statically-linked at compilation time and so released as bundled in the Falco binary. Although no work started yet in this direction, this would solve most issues you reported and would provide a totally-static binary too. Of course, this would not be compatible with dynamic loading anymore, but it may be a viable solution for our static-build flavor of Falco.
9. Memory safety is definitely a concern and we try our best to keep an high level of quality even though C++ is quite error prone. For instance, we try to use smart pointers whenever possible, we build the libraries with an address sanitizer in our CI, we run Falco through Valgrind before each release, and have ways to stress-test it to detect performance regressions or weird memory usage (e.g. https://github.com/falcosecurity/event-generator). On top of that, we also have third parties auditing the codebase by time to time. None of this make a perfect safety standpoint of course, but we try to maximize our odds. Go would definitely make our life easier from this perspective, however the tradeoffs never made it worth it so far due to the points above.
10. The C++ codebase of falcosecurity/libs, which is at the core of Falco, is quite large and complex. Porting all that code to another language would be a major effort requiring lots of development resource and with an high chance of failure and regression. As such, our approach so far has been to choose refactors and code polishing instead, up until we'll reach an optimal level of stability, quality, and modularity, on that portion of code. This would allow further developments to be smoother and more feasibile in the future.

# Falco Release Process
## Overview
This document provides the process to create a new Falco release. In addition, it provides information about the versioning of the Falco components. At a high level each Falco release consists of the following main components:
- Falco binary (userspace), includes `modern_bpf` driver object code (kernel space) starting with Falco 0.34.x releases
- Falco kernel driver object files, separate artifacts for `kmod` and `bpf` drivers, not applicable for `modern_bpf` driver (kernel space)
- Option 1: Kernel module (`.ko` files)
- Option 2: eBPF (`.o` files)
- Falco config and rules `.yaml` files (userspace)
- Falco plugins (userspace - optional)
> Note: Starting with Falco 0.34.x releases, the Falco userspace binary includes the `modern_bpf` driver object code during the linking process. This integration is made possible by the CO-RE (Compile Once - Run Everywhere) feature of the modern BPF driver. CO-RE allows the driver to function on kernels that have backported BTF (BPF Type Format) support or have a kernel version >= 5.8. For the older `kmod` and `bpf` drivers, separate artifacts are released for the kernel space. This is because these drivers need to be explicitly compiled for the specific kernel release, using the exact kernel headers. This approach ensures that Falco can support a wide range of environments, including multiple kernel versions, distributions, and architectures. (see `libs` [driver - kernel version support matrix](https://github.com/falcosecurity/libs#drivers-officially-supported-architectures)).
The Falco Project manages the release of both the Falco userspace binary and pre-compiled Falco kernel drivers for the most popular kernel versions and distros. The build and publish process is managed by the [test-infra](https://github.com/falcosecurity/test-infra) repo.
The Falco userspace executable includes bundled dependencies, so that it can be run from anywhere.
Falco publishes all sources, enabling users to audit the project's integrity and build kernel drivers for custom or unsupported kernels/distributions, specifically for non-modern BPF drivers (see [driverkit](https://github.com/falcosecurity/driverkit) for more information).
Finally, the release process follows a transparent process described in more detail in the following sections and the official [Falco guide and documentation](https://falco.org/) provide rich information around building, installing and using Falco.
### Falco Binaries, Rules and Sources Artifacts - Quick Links
The Falco project publishes all sources and the Falco userspace binaries as GitHub releases.
- [Falco Releases](https://github.com/falcosecurity/falco/releases)
- `tgz`, `rpm` and `deb` Falco binary packages (contains sources, including driver sources, Falco rules as well as k8saudit and cloudtrail plugins)
- `tgz`, `zip` source code
- [Libs Releases](https://github.com/falcosecurity/libs/releases)
- `tgz`, `zip` source code
- [Driver Releases](https://github.com/falcosecurity/libs/releases), marked with `+driver` [build metadata](https://semver.org/).
- `tgz`, `zip` source code
- [Falco Rules Releases](https://github.com/falcosecurity/rules/releases)
- `tgz`, `zip` source code, each ruleset is tagged separately in a mono-repo fashion, see the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md)
Alternatively Falco binaries or plugins can be downloaded from the Falco Artifacts repo.
- [Falco Artifacts Repo Packages Root](https://download.falco.org/?prefix=packages/)
- [Falco Artifacts Repo Plugins Root](https://download.falco.org/?prefix=plugins/)
### Falco Drivers Artifacts Repo - Quick Links
> Note: This section specifically applies to non-modern BPF drivers.
The Falco Project publishes all drivers for each release for popular kernel versions / distros and `x86_64` and `aarch64` architectures to the Falco project's managed Artifacts repo. The Artifacts repo follows standard directory level conventions. The respective driver object file is prefixed by distro and named / versioned by kernel release - `$(uname -r)`. Pre-compiled drivers are released with a [best effort](https://github.com/falcosecurity/falco/blob/master/proposals/20200818-artifacts-storage.md#notice) notice. This is because gcc (`kmod`) and clang (`bpf`) compilers sometimes fail to build the artifacts for a specific kernel version. More details around driver versioning and driver compatibility are provided in the [Falco Components Versioning](#falco-components-versioning) section. Short preview: If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with.
- [Falco Artifacts Repo Drivers Root](https://download.falco.org/?prefix=driver/)
- Option 1: Kernel module (`.ko` files) - all under same driver version directory
- Option 2: eBPF (`.o` files) - all under same driver version directory
### Timeline
Falco follows a release schedule of three times per year, with releases expected at the end of January, May, and September. Hotfix releases are issued as needed.
Changes and new features are organized into [milestones](https://github.com/falcosecurity/falco/milestones). The milestone corresponding to the next version represents the content that will be included in the upcoming release.
### Procedures
The release process is mostly automated, requiring only a few manual steps to initiate and complete.
Moreover, we assign owners for each release (typically pairing a new person with an experienced one). Assignees and due dates for releases are proposed during the [weekly community call](https://github.com/falcosecurity/community).
At a high level each Falco release needs to follow a pre-determined sequencing of releases and build order:
- [1 - 3] `libs` (+ `driver`) and `plugins` components releases
- [4] Falco driver pre-compiled object files push to Falco's Artifacts repo
- [5] Falco userspace binary release
Assignees are responsible for creating a Falco GitHub issue to track the release tasks and monitor the progress of the release. This issue serves as a central point for communication and provides updates on the release dates. You can refer to the [Falco v0.35 release](https://github.com/falcosecurity/falco/issues/2554) or [Libs Release (0.11.0+5.0.1+driver)](https://github.com/falcosecurity/libs/issues/1092) issues as examples/templates for creating the release issue.
Finally, on the proposed due date, the assignees for the upcoming release proceed with the processes described below.
## Pre-Release Checklist
Before proceeding with the release, make sure to complete the following preparatory steps, which can be easily done using the GitHub UI:
### 1. Release notes
- Find the previous release date (`YYYY-MM-DD`) by looking at the [Falco releases](https://github.com/falcosecurity/falco/releases)
- Check the release note block of every PR matching the `is:pr is:merged closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+closed%3A%3EYYYY-MM-DD)
- Ensure the release note block follows the [commit convention](https://github.com/falcosecurity/.github/blob/master/CONTRIBUTING.md#commit-convention), otherwise fix its content
- If the PR has no milestone, assign it to the milestone currently undergoing release
- Check issues without a milestone (using `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD) ) and add them to the milestone currently undergoing release
- Double-check that there are no more merged PRs without the target milestone assigned with the `is:pr is:merged no:milestone closed:>YYYY-MM-DD` [filter](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYY-MM-DD), if any, update those missing
### 2. Milestones
- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
### 3. Release branch
Assuming we are releasing a non-patch version (like: Falco 0.34.0), a new release branch needs to be created.
Its naming will be `release/M.m.x`; for example: `release/0.34.x`.
The same branch will then be used for any eventual cherry pick for patch releases.
For patch releases, instead, the `release/M.m.x` branch should already be in place; no more steps are needed.
Double check that any PR that should be part of the tag has been cherry-picked from master!
### 4. Release PR
The release PR is meant to be made against the respective `release/M.m.x` branch, **then cherry-picked on master**.
- Double-check if any hard-coded version number is present in the code, it should be not present anywhere:
- If any, manually correct it then open an issue to automate version number bumping later
- Versions table in the `README.md` updates itself automatically
- Generate the change log using [rn2md](https://github.com/leodido/rn2md):
- Execute `rn2md -o falcosecurity -m <version> -r falco`
- In case `rn2md` emits error try to generate an GitHub OAuth access token and provide it with the `-t` flag
- Add the latest changes on top the previous `CHANGELOG.md`
- Submit a PR with the above modifications
- Await PR approval
- Close the completed milestone as soon as the PR is merged into the release branch
- Cherry pick the PR on master too
## Publishing Pre-Releases (RCs and tagged development versions)
Core maintainers and/or the release manager can decide to publish pre-releases at any time before the final release
is live for development and testing purposes.
The prerelease tag must be formatted as `M.m.p-r`where `r` is the prerelease version information (e.g. `0.35.0-rc1`.)
To do so:
- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
- Use `M.m.p-r` both as tag version and release title.
- Check the "Set as a pre-release" checkbox and make sure "Set as the latest release" is unchecked
- It is recommended to add a brief description so that other contributors will understand the reason why the prerelease is published
- Publish the prerelease!
- The release pipeline will start automatically. Packages will be uploaded to the `-dev` bucket and container images will be tagged with the specified tag.
In order to check the status of the release pipeline click on the [GitHub Actions tab](https://github.com/falcosecurity/falco/actions?query=event%3Arelease) in the Falco repository and filter by release.
## Release
Assume `M.m.p` is the new version.
### 1. Create the release with GitHub
- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
- Use `M.m.p` both as tag version and release title
- Do NOT fill body, since it will be autogenerated by the [github release workflow](.github/workflows/release.yaml)
- Publish the release!
- The release pipeline will start automatically upon publication and all packages and container images will be uploaded to the stable repositories.
In order to check the status of the release pipeline click on the [GitHub Actions tab](https://github.com/falcosecurity/falco/actions?query=event%3Arelease) in the Falco repository and filter by release.
### 2. Update the meeting notes
For each release we archive the meeting notes in git for historical purposes.
- The notes from the Falco meetings can be [found here](https://hackmd.io/3qYPnZPUQLGKCzR14va_qg).
- Note: There may be other notes from working groups that can optionally be added as well as needed.
- Add the entire content of the document to a new file in [github.com/falcosecurity/community/tree/master/meeting-notes](https://github.com/falcosecurity/community/tree/master/meeting-notes) as a new file labeled `release-M.m.p.md`
- Open up a pull request with the new change.
## Post-Release tasks
Announce the new release to the world!
- Publish a blog on [Falco website](https://github.com/falcosecurity/falco-website) ([example](https://github.com/falcosecurity/falco-website/blob/master/content/en/blog/falco-0-28-1.md))
- Send an announcement to cncf-falco-dev@lists.cncf.io (plain text, please)
- Let folks in the slack #falco channel know about a new release came out
- IFF the on going release introduces a **new minor version**, [archive a snapshot of the Falco website](https://github.com/falcosecurity/falco-website/blob/master/release.md#documentation-versioning)
## Falco Components Versioning
This section provides more details around the versioning of the components that make up Falco's core. It can also be a useful guide for the uninitiated to be more informed about Falco's source. Because `libs` makes up the greater portion of the source code of the Falco binary and is the home of each of the kernel drivers and engines, the [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) is an excellent additional resource. In addition, the [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) provides similar details around Falco's plugins. `SHA256` checksums are provided throughout Falco's source code to empower the end user to perform integrity checks. All Falco releases also contain the sources as part of the packages.
### Falco repo (this repo)
- Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax and loading logic, and/or when `FALCO_ENGINE_CHECKSUM` has changed. The checksum is computed by considering the available rules fields (see currently supported [Falco fields](https://falco.org/docs/reference/rules/supported-fields/)), the event types (see currently supported [Falco events](https://falco.org/docs/reference/rules/supported-events/)), and the supported driver schema version. A checksum indicates that something was not available in previous engine versions. See the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md#versioning-a-ruleset) to understand how this affects the versioning of Falco rules. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The version number must be incremented every time and only when a single change or an atomic group of changes - which meet the criteria described above - is included in the `master` branch. Thus, a version bump can occur multiple times during the development and testing phases of a given release cycle. A given version bump must not group multiple changes that occurred sporadically during the release cycle.
- During development and release preparation, libs and driver reference commits are often bumped in Falco's cmake setup ([falcosecurity-libs cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/falcosecurity-libs.cmake#L30) and [driver cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/driver.cmake#L29)) in order to merge new Falco features. In practice, they are mostly bumped at the same time referencing the same `libs` commit. However, for the official Falco build `FALCOSECURITY_LIBS_VERSION` flag that references the stable libs version is used (read below).
- Similarly, Falco plugins versions are bumped in Falco's cmake setup ([plugins cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/plugins.cmake)) and those versions are the ones used for the Falco release.
- At release time Plugin, Libs and Driver versions are compatible with Falco.
- If you use the standard Falco setup leveraging driver-loader, [driver-loader script](https://github.com/falcosecurity/falco/blob/master/scripts/falco-driver-loader) will fetch the kernel space artifact (object file) corresponding to the default `DRIVER_VERSION` Falco was shipped with (read more below under Libs).
```
Falco version: x.y.z (sem-ver like)
Libs version: x.y.z (sem-ver like)
Plugin API: x.y.z (sem-ver like)
Engine: x
Driver:
API version: x.y.z (sem-ver)
Schema version: x.y.z (sem-ver)
Default driver: x.y.z+driver (sem-ver like, indirectly encodes compatibility range in addition to default version Falco is shipped with)
```
### Libs repo
- Libs version is a git tag (`x.y.z`) and when building Falco the libs version is set via the `FALCOSECURITY_LIBS_VERSION` flag (see above).
- The driver version is not directly linked to the userspace components of the Falco binary. This is because of the clear separation between userspace and kernel space, which adds an additional layer of complexity. To address this, the concept of a `Default driver` has been introduced, allowing for implicit declaration of compatible driver versions. For example, if the default driver version is `5.0.1+driver`, Falco works with all driver versions >= 5.0.1 and < 6.0.0. This is a consequence of how the driver version is constructed starting from the `Driver API version` and `Driver Schema version`. Driver API and Schema versions are explained in the respective [libs driver doc](https://github.com/falcosecurity/libs/blob/master/driver/README.VERSION.md) -> Falco's `driver-loader` will always fetch the default driver, therefore a Falco release is always "shipped" with the driver version corresponding to the default driver.
- See [libs release doc](https://github.com/falcosecurity/libs/blob/master/release.md) for more information.
### Plugins repo
- Plugins version is a git tag (`x.y.z`)
- See [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) for more information.
### Rules repo
- Rulesets are versioned individually through git tags
- See [rules release doc](https://github.com/falcosecurity/rules/blob/main/RELEASE.md) for more information.
- See [plugins release doc](https://github.com/falcosecurity/plugins/blob/master/release.md) for more information about plugins rulesets.

---
# Glossary
This section contains key terms specifically used within the context of The Falco Project. For a more comprehensive list of Falco-related terminology, we invite you to visit the [Glossary](https://falco.org/docs/reference/glossary/) page on our official website.
#### eBPF Probe
Used to describe the `.o` object that would be dynamically loaded into the kernel as a secure and stable (e)BPF probe.
This is one option used to pass kernel events up to userspace for Falco to consume.
#### Modern eBPF Probe
More robust [eBPF probe](#ebpf-probe), which brings the CO-RE paradigm, better performances, and maintainability.
Unlike the legacy probe, the modern eBPF probe is not shipped as a separate artifact but bundled into the Falco binary itself.
This is one option used to pass kernel events up to userspace for Falco to consume.
#### Kernel Module
Used to describe the `.ko` object that would be loaded into the kernel as a potentially risky kernel module.
This is one option used to pass kernel events up to userspace for Falco to consume.
#### Driver
The global term for the software that sends events from the kernel. Such as the [eBPF probe](#ebpf-probe), the [Modern eBPF probe](#modern-ebpf-probe), or the [Kernel Module](#kernel-module).
#### Plugin
Used to describe a dynamic shared library (`.so` files in Unix, `.dll` files in Windows) that conforms to a documented API and allows to extend Falco's capabilities.
#### Falco
The name of the project and also the name of [the main engine](https://github.com/falcosecurity/falco) that the rest of the project is built on.

#[=======================================================================[.rst:
Catch
-----
This module defines a function to help use the Catch test framework.
The :command:`catch_discover_tests` discovers tests by asking the compiled test
executable to enumerate its tests. This does not require CMake to be re-run
when tests change. However, it may not work in a cross-compiling environment,
and setting test properties is less convenient.
This command is intended to replace use of :command:`add_test` to register
tests, and will create a separate CTest test for each Catch test case. Note
that this is in some cases less efficient, as common set-up and tear-down logic
cannot be shared by multiple test cases executing in the same instance.
However, it provides more fine-grained pass/fail information to CTest, which is
usually considered as more beneficial. By default, the CTest test name is the
same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
.. command:: catch_discover_tests
Automatically add tests with CTest by querying the compiled test executable
for available tests::
catch_discover_tests(target
[TEST_SPEC arg1...]
[EXTRA_ARGS arg1...]
[WORKING_DIRECTORY dir]
[TEST_PREFIX prefix]
[TEST_SUFFIX suffix]
[PROPERTIES name1 value1...]
[TEST_LIST var]
)
``catch_discover_tests`` sets up a post-build command on the test executable
that generates the list of tests by parsing the output from running the test
with the ``--list-test-names-only`` argument. This ensures that the full
list of tests is obtained. Since test discovery occurs at build time, it is
not necessary to re-run CMake when the list of tests changes.
However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
in order to function in a cross-compiling environment.
Additionally, setting properties on tests is somewhat less convenient, since
the tests are not available at CMake time. Additional test properties may be
assigned to the set of tests as a whole using the ``PROPERTIES`` option. If
more fine-grained test control is needed, custom content may be provided
through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
directory property. The set of discovered tests is made accessible to such a
script via the ``<target>_TESTS`` variable.
The options are:
``target``
Specifies the Catch executable, which must be a known CMake executable
target. CMake will substitute the location of the built executable when
running the test.
``TEST_SPEC arg1...``
Specifies test cases, wildcarded test cases, tags and tag expressions to
pass to the Catch executable with the ``--list-test-names-only`` argument.
``EXTRA_ARGS arg1...``
Any extra arguments to pass on the command line to each test case.
``WORKING_DIRECTORY dir``
Specifies the directory in which to run the discovered test cases. If this
option is not provided, the current binary directory is used.
``TEST_PREFIX prefix``
Specifies a ``prefix`` to be prepended to the name of each discovered test
case. This can be useful when the same test executable is being used in
multiple calls to ``catch_discover_tests()`` but with different
``TEST_SPEC`` or ``EXTRA_ARGS``.
``TEST_SUFFIX suffix``
Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
every discovered test case. Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
be specified.
``PROPERTIES name1 value1...``
Specifies additional properties to be set on all tests discovered by this
invocation of ``catch_discover_tests``.
``TEST_LIST var``
Make the list of tests available in the variable ``var``, rather than the
default ``<target>_TESTS``. This can be useful when the same test
executable is being used in multiple calls to ``catch_discover_tests()``.
Note that this variable is only available in CTest.

# Falco Dockerfiles
This directory contains various ways to package Falco as a container and related tools.
## Currently Supported Images
| Name | Directory | Description |
|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [falcosecurity/falco:latest](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:master](https://hub.docker.com/repository/docker/falcosecurity/falco) | docker/falco | Distroless image based on the latest released tar.gz of Falco. No tools are included in the image. |
| [falcosecurity/falco:latest-debian](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:_tag_-debian](https://hub.docker.com/repository/docker/falcosecurity/falco), [falcosecurity/falco:master-debian](https://hub.docker.com/repository/docker/falcosecurity/falco) | docker/falco-debian | Debian-based image. Include some tools (i.e. jq, curl). No driver-building toolchain support. |
| [falcosecurity/falco-driver-loader:latest](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:_tag_](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:master](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader) | docker/driver-loader | Based on falcosecurity/falco:x.y.z-debian (see above) plus the driver building toolchain support and falcoctl. This is intended to be used as an installer or an init container when modern eBPF cannot be used. |
| [falcosecurity/falco-driver-loader:latest-buster](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:_tag_-buster](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader), [falcosecurity/falco-driver-loader:master-debian](https://hub.docker.com/repository/docker/falcosecurity/falco-driver-loader) | docker/driver-loader-buster | Similar to falcosecurity/falco-driver-loader (see above) but based on a legacy Debian image (i.e. buster ). Recommended only for old kernel versions. |

Hello, this is the Falco builder container.
How to use.
The default commands for the Falco builder image reports usage and environment info.
* docker run falcosecurity/falco-builder
* docker run falcosecurity/falco-builder usage
It supports bash.
* docker run -ti falcosecurity/falco-builder bash
To build Falco it needs:
- a bind-mount on the source directory (ie., the directory containing falco and sysdig source as siblings)
Optionally, you can also bind-mount the build directory.
So, you can execute it from the Falco root directory as follows.
* docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder cmake
* docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder [<cmake-target-x>, ..., <cmake-target-y>]
Eg.,
* docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder tests
* docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder install
How to build.
* cd docker/builder && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-builder .
In case you want to customise the builder at build time the following build arguments are provided:
- BUILD_TYPE whether you want a "release" or "debug" build (defaults to "release").
- BUILD_DRIVER whether to build the driver or not (defaults to "OFF")
- BUILD_BPF whether to build the BPF driver or not (defaults to "OFF")
- BUILD_WARNINGS_AS_ERRORS whether to intend warnings as errors or not (defaults to "ON")
- MAKE_JOBS the number of jobs to use during make (defaults to "4")
- FALCO_VERSION the version to label the build (built from git index in case it is missing)
It is possible to change these at runtime (in the container) since environment variables with the same names are provided, too.
Environment.
* ${gccversion}
* cplusplus ${cppversion}
* ${cmakeversion}
