Note

• This issue is similar to Docker for Mac 4.18.0 deprecatedCgroupv1 flag is being ignored moby/moby#45303 since that ticket was closed with the suggestion to raise it here instead. I am not the original poster there, but it seems like I have the same issue.

Expected behavior

With deprecatedCgroupv1 set to true under /Users/$(whoami)/Library/Group\ Containers/group.com.docker/settings.json, Docker should be using cgroup v1 instead of v2.

➜  ~ cat /Users/$(whoami)/Library/Group\ Containers/group.com.docker/settings.json | grep deprecatedCgroupv1

  "deprecatedCgroupv1": true,
➜  ~ /usr/local/bin/docker info --format '{{json .CgroupVersion}}'
"1"
➜  ~

Actual behavior

On the latest 4.18.0 version, this is ignored, and Docker is using cgroup v2 regardless of the property.

➜  ~ cat /Users/$(whoami)/Library/Group\ Containers/group.com.docker/settings.json | grep deprecatedCgroupv1

  "deprecatedCgroupv1": true,
➜  ~ /usr/local/bin/docker info --format '{{json .CgroupVersion}}'
"2"
➜  ~

Reverting back to 4.17.0 resolves the issue.

Information

To reproduce

1. Install 4.17.0
2. After installation, quit Docker Desktop completely.
3. Set the value of deprecatedCgroupv1 under /Users/$(whoami)/Library/Group\ Containers/group.com.docker/settings.json to true
   • Add the property if missing
4. Start Docker Desktop
5. Open Terminal:
   1. Verify that the property remained true: cat /Users/$(whoami)/Library/Group\ Containers/group.com.docker/settings.json | grep deprecatedCgroupv1 (if no, repeat steps 2-4 above)
   2. Verify that cgroup version is 1: /usr/local/bin/docker info --format '{{json .CgroupVersion}}'

After confirming the above, upgrade to (the latest) 4.18.0. Steps 2-4 should be remembered, so you can go directly to step 5 above.
