The rpc only reports one field, i.e. the cgroup driver, to kubelet. Containerd determines the effective cgroup driver by looking at all runtime handlers, starting from the default runtime handler (the rest in alphabetical order), and returning the cgroup driver setting of the first runtime handler that supports one. If no runtime handler supports cgroup driver (i.e. has a config option for it) containerd falls back to auto-detection, returning systemd if systemd is running and cgroupfs otherwise. This patch implements the CRI server side of Kubernetes KEP-4033: https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/4033-group-driver-detection-over-cri Signed-off-by: Markus Lehtonen <markus.lehtonen@intel.com>
