[adityacloud]

Hi,
I am trying to checkpoint and restore a test container using https://criu.org/Docker#TTY url
, and checkpoint command gives me the "Error response from daemon: custom checkpointdir is not supported" error.

Any help will be appreciated.

Hi @adityacloud
This is not an issue with CRIU. See containerd/containerd#2053

It is not yet implemented in docker:

if checkpointDir != "" {
	// TODO(mlaventure): how would we support that?
	return errdefs.Forbidden(errors.New("custom checkpointdir is not supported"))
}

Thanks sir, I will try to modify docker configuration files.
