Adrian Reber	218e2cf7cd	Return correct error if CRIU binary is missing ... For the first version of containerd's "Forensic Container Checkpointing" support the error message if the CRIU binary is not found was deliberately wrong to not break Kubernetes e2e_node tests. Now that the e2e_node tests have been adapted, containerd can return the correct error message. Signed-off-by: Adrian Reber <areber@redhat.com>	2024-03-12 08:29:30 +00:00
Adrian Reber	f25770e48d	Wire through CRI ContainerCheckpoint RPC ... 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.
