Custom containerd Configuration

In case a Shoot cluster uses containerd, it is possible to make the containerd process load custom configuration files. Gardener initializes containerd 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. To prevent unintended configuration overwrites, please be aware that containerd merges config sections, not individual keys (see here and here). 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.
