Error cgroup using docker plugin

Drone Support
1

Hi

I’m using drone on debian testing machine and since fews days I encountered the following error:

---> Running in 735f5efc0fd0
132 cgroups: cgroup mountpoint does not exist: unknown
133 time="2021-03-15T12:50:25Z" level=fatal msg="exit status 1"

It think docker was updated on my server.
The pipeline was working perfectly last month.

I tried to run docker build manually with the same Dockerfile than in the pipeline and it worked fine.
I think I missed something but I don’t know what.
Can you help me or give me some clues for investigation ?

Here is the docker plugin pipeline step:

- name: dockerise
  image: plugins/docker
  network_mode: host
  settings:
    registry: x.x.x.x:yyyy
    repo: x.x.x.x:yyyy/myrepo
    debug: false
    insecure: true
    force_tag: true
    build_args:
      - SERVER_PORT=pppp
    username:
      from_secret: registry_username
    password:
      from_secret: registry_password
    tags:
      - latest

I undestand the problem comes from cgroup v2, but I don’t see a way to make it work with docker plugin

Thank you for your support :wink:

Is there some reason to believe the problem comes from difference between host docker version 20.10.5 and used in drone docker plugin 19.03.8 ?

Maybe the fact is debian enables by default cgroup v2 and drone docker plugin is not yet compatible with host configuration ?

I’m really confused about this problem and I don’t know what to do.
Any help will be really appreciated :sweat_smile:

Thanks again

The docker plugin is a small wrapper around the official docker:dind image [1]. I would therefore recommend running the official docker:dind container on your host, collecting the error message in the logs, and then report to the docker team (see sample commands below). The docker maintainers will be the most qualified to help you troubleshoot problems with docker-in-docker.

$ docker run --privileged --name dind -d docker:19.03.8-dind
$ sleep 15
$ docker logs dind

Thank you very much for your answer.

I finally completely drop docker plugin usage and switch to DooD method.
As my repo is completely private, I should not encounter security issue :wink:

Just a question about docker plugin, is there a reason to force docker:dind image to 19.03 instead of using latest one (that changed to 20.10.5 few days ago) ?

Thank you again

I haven’t looked at the latest release, however, 19.03 is the last dind image that includes 32-bit arm support. Upgrading dind to 20.x would break 32-bit arm pipelines. There is an open issue in the Docker repositroy, and they have a fix planned, which is what we are waiting for before upgrading.

Sorry, I got same problem too. So…It still not solved?

Same problem here.

Is there documentation/examples on alternative ways to build and push the docker image?

Documentation on how to build the Docker image: GitHub - drone-plugins/drone-docker: Drone plugin for publishing Docker images using Docker-in-Docker

The active ticket where this Drone issue is being worked, including a link to an alternate image someone is hosting (use at your own risk): Update Docker dind to 20.10.7-dind by prologic · Pull Request #327 · drone-plugins/drone-docker · GitHub

As work around for now you can use:
Add systemd.unified_cgroup_hierarchy=0 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub

don’t forget to update grub and reboot after that.

update-grub
12

it works.
I change /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=“systemd.unified_cgroup_hierarchy=0”
and changed cgroup to v1 …it wokrs.
thx a lot
