Why is docker checkpoint not working when experimental is set to true?


I have:

cat /etc/docker/daemon.json
  "experimental": true

sudo apt-get install -y criu        
Reading package lists... Done
Building dependency tree       
Reading state information... Done
criu is already the newest version (3.14-1).

sudo kill -SIGHUP $(pidof dockerd)
docker checkpoint create cc61c202c903 J1
docker checkpoint create is only supported on a Docker daemon with experimental features enabled

Why is docker checkpoint not working?

FWIW, I’m following the sketchy docs here: https://docs.docker.com/engine/reference/commandline/checkpoint/


cat /etc/os-release  NAME="Ubuntu" VERSION="20.10 (Groovy Gorilla)"


docker version
Client: Docker Engine - Community
 Version:           19.03.11
