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](https://katacontainers.io). ## 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](LICENSE) for further details. ## Platform support Kata Containers currently runs on 64-bit systems supporting the following technologies: | Architecture | Virtualization technology | |-|-| | `x86_64`, `amd64` | [Intel](https://www.intel.com) VT-x, AMD SVM | | `aarch64` ("`arm64`")| [ARM](https://www.arm.com) Hyp | | `ppc64le` | [IBM](https://www.ibm.com) Power | | `s390x` | [IBM](https://www.ibm.com) Z & LinuxONE SIE | ### Hardware requirements The [Kata Containers runtime](src/runtime) provides a command to determine if your host system is capable of running and creating a Kata Container: ```bash $ 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-checks` option. > > - By default, only a brief success / failure message is printed. > If more details are needed, the `--verbose` flag can be used to display the > list of all the checks performed. > > - If the command is run as the `root` user additional checks are > run (including checking if another incompatible hypervisor is running). > When running as `root`, network checks are automatically disabled. ## Getting started See the [installation documentation](docs/install). ## Documentation See the [official documentation](docs) including: - [Installation guides](docs/install) - [Developer guide](docs/Developer-Guide.md) - [Design documents](docs/design) - [Architecture overview](docs/design/architecture) - [Architecture 3.0 overview](docs/design/architecture_3.0/) ## Configuration Kata Containers uses a single [configuration file](src/runtime/README.md#configuration) which contains a number of sections for various parts of the Kata Containers system including the [runtime](src/runtime), the [agent](src/agent) and the [hypervisor](#hypervisors). ## Hypervisors See the [hypervisors document](docs/hypervisors.md) and the [Hypervisor specific configuration details](src/runtime/README.md#hypervisor-specific-configuration). ## Community To learn more about the project, its community and governance, see the [community repository](https://github.com/kata-containers/community). This is the first place to go if you wish to contribute to the project. ## Getting help See the [community](#community) section for ways to contact us. ### Raising issues Please raise an issue [in this repository](https://github.com/kata-containers/kata-containers/issues). > **Note:** > If you are reporting a security issue, please follow the [vulnerability reporting process](https://github.com/kata-containers/community#vulnerability-handling) ## Developers See the [developer guide](docs/Developer-Guide.md). ### Components ### Main components The table below lists the core parts of the project: | Component | Type | Description | |-|-|-| | [runtime](src/runtime) | core | Main component run by a container manager and providing a containerd shimv2 runtime implementation. | | [runtime-rs](src/runtime-rs) | core | The Rust version runtime. | | [agent](src/agent) | core | Management process running inside the virtual machine / POD that sets up the container environment. | | [`dragonball`](src/dragonball) | core | An optional built-in VMM brings out-of-the-box Kata Containers experience with optimizations on container workloads | | [documentation](docs) | documentation | Documentation common to all components (such as design and install documentation). | | [tests](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](tools/packaging) | infrastructure | Scripts and metadata for producing packaged binaries<br/>(components, hypervisors, kernel and rootfs). | | [kernel](https://www.kernel.org) | kernel | Linux kernel used by the hypervisor to boot the guest image. Patches are stored [here](tools/packaging/kernel). | | [osbuilder](tools/osbuilder) | infrastructure | Tool to create "mini O/S" rootfs and initrd images and kernel for the hypervisor. | | [kata-debug](tools/packaging/kata-debug/README.md) | infrastructure | Utility tool to gather Kata Containers debug information from Kubernetes clusters. | | [`agent-ctl`](src/tools/agent-ctl) | utility | Tool that provides low-level access for testing the agent. | | [`kata-ctl`](src/tools/kata-ctl) | utility | Tool that provides advanced commands and debug facilities. | | [`trace-forwarder`](src/tools/trace-forwarder) | utility | Agent tracing helper. | | [`runk`](src/tools/runk) | utility | Standard OCI container runtime based on the agent. | | [`ci`](.github/workflows) | CI | Continuous Integration configuration files and scripts. | | [`ocp-ci`](ci/openshift-ci/README.md) | CI | Continuous Integration configuration for the OpenShift pipelines. | | [`katacontainers.io`](https://github.com/kata-containers/www.katacontainers.io) | Source for the [`katacontainers.io`](https://www.katacontainers.io) site. | | [`Webhook`](tools/testing/kata-webhook/README.md) | utility | Example of a simple admission controller webhook to annotate pods with the Kata runtime class | ### Packaging and releases Kata Containers is now [available natively for most distributions](docs/install/README.md#packaged-installation-methods). ## General tests See the [tests documentation](tests/README.md). ## Metrics tests See the [metrics documentation](tests/metrics/README.md). ## Glossary of Terms See the [glossary of terms](https://github.com/kata-containers/kata-containers/wiki/Glossary) related to Kata Containers.
