I am attempting to use docker checkpoint
in my Ubuntu 18 WSL2 environment on a container that was started with docker compose
.
The command I am using is docker checkpoint create --checkpoint-dir=./states main-1 statename
.
The error I get back is:
Error response from daemon: Cannot checkpoint container main-1: runc did not terminate successfully: exit status 1: CRIU version check failed: exec: "criu": executable file not found in $PATH path= /var/run/desktop-containerd/daemon/io.containerd.runtime.v2.task/moby/fc9b7b3a00b6208753653f31250fb48af8500d22c7889173e7b3276070b7ce30/criu-dump.log: unknown
I installed criu into my WSL using these commands:
sudo add-apt-repository ppa:criu/ppa
sudo apt-get update
sudo apt-get install criu
I know that criu is installed because I can run the executable:
service@laptop1: ~/$ criu
Usage:
criu dump|pre-dump -t PID [<options>]
criu restore [<options>]
criu check [--feature FEAT]
criu page-server
criu service [<options>]
criu dedup
criu lazy-pages -D DIR [<options>]
Commands:
dump checkpoint a process/tree identified by pid
pre-dump pre-dump task(s) minimizing their frozen time
restore restore a process/tree
check checks whether the kernel support is up-to-date
page-server launch page server
service launch service
dedup remove duplicates in memory dump
cpuinfo dump writes cpu information into image file
cpuinfo check validates cpu information read from image file
Try -h|--help for more info
Output of which criu
:
/usr/sbin/criu
I have also made sure that I have enabled experimental features for docker.
Please let me know if theres anymore info I can provide. Thanks!
I also uninstalled and reinstalled criu and got the same result
This was due to not running criu as root sudo criu
