Custom containerd Configuration

In case a Shoot cluster uses containerd (see this document) for more information), it is possible to make the containerd process load custom configuration files. Gardener initializes contaienerd with the following statement:

imports = ["/etc/containerd/conf.d/*.toml"]

This means that all *.toml files in the /etc/containerd/conf.d directory will be imported and merged with the default configuration. Please consult the upstream containerd documentation for more information.

⚠️ Note that this only applies to nodes which were newly created after gardener/gardener@v1.51 was deployed. Existing nodes are not affected.
