This connects the new CRI ContainerCheckpoint RPC to the existing internal checkpoint functions. With this commit it is possible to checkpoint a container in Kubernetes using the Forensic Container Checkpointing KEP (#2008): # curl X POST "https://localhost:10250/checkpoint/namespace/podId/container" Which will result in containerd creating a checkpoint in the location specified by Kubernetes (usually /var/lib/kubelet/checkpoints). This is a Linux only feature because CRIU only exists on Linux. Rewritten with the help of Phil Estes. Signed-off-by: Phil Estes <estesp@gmail.com> Signed-off-by: Adrian Reber <areber@redhat.com>
