## Compatibility with CRI-O
|
|
Kata Containers ${runtime_version} is compatible with CRI-O ${crio_version}
|
|
|
|
## Compatibility with containerd
|
|
Kata Containers ${runtime_version} is compatible with contaienrd ${containerd_version}
|
|
|
|
## OCI Runtime Specification
|
|
Kata Containers ${runtime_version} support the OCI Runtime Specification [${oci_spec_version}][ocispec]
|
|
|
|
## Compatibility with Kubernetes
|
|
Kata Containers ${runtime_version} is compatible with Kubernetes ${kubernetes_version}
|
|
|
|
## Libseccomp Notices
|
|
The \`kata-agent\` binaries inside the Kata Containers images provided with this release are
|
|
statically linked with the following [GNU LGPL-2.1][lgpl-2.1] licensed libseccomp library.
|
|
|
|
* [\`libseccomp\`][libseccomp]
|
|
|
|
The \`kata-agent\` uses the libseccomp v${libseccomp_version} which is not modified from the upstream version.
|
|
However, in order to comply with the LGPL-2.1 (§6(a)), we attach the complete source code for the library.
|
|
|
|
If you want to use the \`kata-agent\` which is not statically linked with the library, you can build
|
|
a custom \`kata-agent\` that does not use the library from sources.
|
|
For the details, please check the [developer guide][custom-agent-doc].

## Kata Linux Containers image
|
|
Agent version: ${new_release}
|
|
|
|
### Default Image Guest OS:
|
|
${image_info}

|
### Default Initrd Guest OS:

## Kata Containers builder images
|
|
The majority of the components of the project were built using containers. In order to do a step towards
|
|
build reproducibility we publish those container images, and when those are used combined with the version
|
|
of the projects listed as part of the "versions.yaml" file, users can get as close to the environment we
|
|
used to build the release artefacts.
|
|
* agent (on all its different flavours): $(get_agent_image_name)
|
|
* Kernel (on all its different flavours): $(get_kernel_image_name)
|
|
* OVMF (on all its different flavours): $(get_ovmf_image_name)
|
|
* QEMU (on all its different flavurs): $(get_qemu_image_name)
|
|
* shim-v2: $(get_shim_v2_image_name)
|
|
* tools: $(get_tools_image_name)
|
|
* virtiofsd: $(get_virtiofsd_image_name)
|
|
|
|
The users who want to rebuild the tarballs using exactly the same images can simply use the following environment
|
|
variables:
|
|
* \`AGENT_CONTAINER_BUILDER\`
|
|
* \`KERNEL_CONTAINER_BUILDER\`
|
|
* \`OVMF_CONTAINER_BUILDER\`
|
|
* \`QEMU_CONTAINER_BUILDER\`
|
|
* \`SHIM_V2_CONTAINER_BUILDER\`
|
|
* \`TOOLS_CONTAINER_BUILDER\`
|
|
* \`VIRTIOFSD_CONTAINER_BUILDER\`
|

|
|
See the kernel suggested [Guest Kernel patches][kernel-patches]
|
|
See the kernel suggested [Guest Kernel config][kernel-config]
