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 licensed libseccomp library.

• libseccomp

The kata-agent uses the libseccomp v2.5.4 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.

Kata Linux Containers image

Agent version: 3.0.0-rc0

Default Image Guest OS:

description: | Root filesystem disk image used to boot the guest virtual machine. url: "https://github.com/kata-containers/kata-containers/tools/osbuilder" architecture: aarch64: name: "ubuntu" version: "latest" ppc64le: name: "ubuntu" version: "latest" s390x: name: "ubuntu" version: "latest" x86_64: name: "clearlinux" version: "latest" meta: image-type: "clearlinux"

Do not use Alpine on ppc64le & s390x, the agent cannot use musl because

there is no such Rust target

ppc64le: name: "ubuntu" version: "20.04" s390x: name: "ubuntu" version: "20.04" x86_64: name: "alpine" version: "3.15"
