[eskuai]

Hello,

I am following the instructions from https://technology.amis.nl/2018/04/08/first-steps-with-docker-checkpoint-to-create-and-restore-snapshots-of-running-containers/ I got

[root@k8s-master ~]# docker checkpoint create  --leave-running=true cr checkpoint0
Error response from daemon: Cannot checkpoint container cr: /usr/local/bin/crun did not terminate sucessfully: unknown command checkpoint path= /run/containerd/io.containerd.runtime.v1.linux/moby/2703213fe2b0f727e5cfecad9de32f3d1e1340301aab43e5a1c1509d019cc57e/criu-dump.log: unknown

it logs:

cr: /usr/local/bin/crun did not terminate sucessfully

I dont know it is a crun problem ...

Can be closed. See https://github.com/checkpoint-restore/criu/issues/1291. Wrong CRIU version and wrong crun version. This crun version does not support checkpoint/restore, yet.

@eskuai you'll need crun 0.16 once it is released: https://github.com/containers/crun/pull/548
