Adds cargo-deny to scan for vulnerabilities and license issues regarding rust crates. GitHub Actions does not have an obvious way to loop over each of the Cargo.toml files. To avoid hardcoding it, I worked around the problem using a composite action that first generates the cargo-deny action by finding all Cargo.toml files before calling this new generated action in the master workflow. Uses recommended deny.toml from cargo-deny repo with the following modifications: ignore = ["RUSTSEC-2020-0071"] because chrono is dependent on the version of time with the vulnerability and there is no simple workaround multiple-versions = "allow" Because of the above error and other packages, there are instances where some crates require different versions of a crate. unknown-git = "allow" I don't see a particular issue with allowing crates from other repos. An alternative would be the manually set each repo we want in an allow-git list, but I see this as more of a nuisance that its worth. We could leave this as a warning (default), but to avoid clutter I'm going to allow it. If deny.toml needs to be edited in the future, here's the guide: https://embarkstudios.github.io/cargo-deny/index.html Fixes #3359 Signed-off-by: Derek Lee <derlee@redhat.com> |

Kata Containers
Welcome to Kata Containers!
This repository is the home of the Kata Containers code for the 2.0 and newer releases.
If you want to learn about Kata Containers, visit the main Kata Containers website.
Introduction
Kata Containers is an open source project and community working to build a standard implementation of lightweight Virtual Machines (VMs) that feel and perform like containers, but provide the workload isolation and security advantages of VMs.
License
The code is licensed under the Apache 2.0 license. See the license file for further details.
Platform support
Kata Containers currently runs on 64-bit systems supporting the following technologies:
| Architecture | Virtualization technology |
|---|---|
x86_64, amd64 |
Intel VT-x, AMD SVM |
aarch64 ("arm64") |
ARM Hyp |
ppc64le |
IBM Power |
s390x |
IBM Z & LinuxONE SIE |
Hardware requirements
The Kata Containers runtime provides a command to determine if your host system is capable of running and creating a Kata Container:
$ kata-runtime check
Notes:
This command runs a number of checks including connecting to the network to determine if a newer release of Kata Containers is available on GitHub. If you do not wish this to check to run, add the
--no-network-checksoption.By default, only a brief success / failure message is printed. If more details are needed, the
--verboseflag can be used to display the list of all the checks performed.If the command is run as the
rootuser additional checks are run (including checking if another incompatible hypervisor is running). When running asroot, network checks are automatically disabled.
Getting started
See the installation documentation.
Documentation
See the official documentation including:
Configuration
Kata Containers uses a single configuration file which contains a number of sections for various parts of the Kata Containers system including the runtime, the agent and the hypervisor.
Hypervisors
See the hypervisors document and the Hypervisor specific configuration details.
Community

Components
Main components
The table below lists the core parts of the project:
| Component | Type | Description |
|---|---|---|
| runtime | core | Main component run by a container manager and providing a containerd shimv2 runtime implementation. |
| agent | core | Management process running inside the virtual machine / POD that sets up the container environment. |
| libraries | core | Library crates shared by multiple Kata Container components or published to crates.io |
dragonball |
core | An optional built-in VMM brings out-of-the-box Kata Containers experience with optimizations on container workloads |
| documentation | documentation | Documentation common to all components (such as design and install documentation). |
| libraries | core | Library crates shared by multiple Kata Container components or published to crates.io |
| tests | tests | Excludes unit tests which live with the main code. |
Additional components
The table below lists the remaining parts of the project:
| Component | Type | Description |
|---|---|---|
| packaging | infrastructure | Scripts and metadata for producing packaged binaries (components, hypervisors, kernel and rootfs). |
| kernel | kernel | Linux kernel used by the hypervisor to boot the guest image. Patches are stored here. |
| osbuilder | infrastructure | Tool to create "mini O/S" rootfs and initrd images and kernel for the hypervisor. |
agent-ctl |
utility | Tool that provides low-level access for testing the agent. |
trace-forwarder |
utility | Agent tracing helper. |
runk |
utility | Standard OCI container runtime based on the agent. |
ci |
CI | Continuous Integration configuration files and scripts. |

Packaging and releases
Kata Containers is now available natively for most distributions. However, packaging scripts and metadata are still used to generate snap and GitHub releases. See the components section for further details.
