QUESTION
The executor for the project gitlab-runner is docker. I try to run docker-in-docker and I get the following Error from pipeline:
ERROR: Job failed (system failure): Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: process_linux.go:545: container init caused: process_linux.go:508: setting cgroup config for procHooks process caused: resulting devices cgroup doesn't match target mode: unknown (docker.go:385:0s)
I followed this guide: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-continuous-deployment-pipeline-with-gitlab-ci-cd-on-ubuntu-18-04 and after I read the docs of gitlab CI/CD and gitlab-runner, but I can't find out how to solve this problem.
This is currently my config.toml file:

Answered 2021-Jun-10 at 21:28I solved it with a downgrade of docker:
sudo apt-get install --reinstall docker-ce=5:18.09.9~3-0~ubuntu-bionic docker-ce-cli=5:18.09.9~3-0~ubuntu-bionic docker-ce-rootless-extras containerd.io=1.3.9-1
The problem was that I run on a V-Server (Virtuozzo) with Ubuntu 18. It seems that Virtuozzo does not support currently the newest Docker Engine.
QUESTION
I have a Dind image (docker in docker). I want to share images between containers that are loaded inside containers. How to do it? What folders should I mount?
Thanks.
...ANSWER
Answered 2021-Jun-08 at 11:08The Docker image storage format is complex and installation-specific. If you have two installations of Docker, they can't share images, even if they're running on the same physical system.
That means you need to use one of the normal means of transferring images between locations: docker push
and docker pull
the images via a registry; docker build
an image from source where you need it; or use docker save
and docker load
to create an intermediate tar file. If the DinD container is named dind
, in principle you should be able to

Answered 2021-Jun-04 at 08:49It looks like a bug indeed: CI_REGISTRY_PASSWORD
variable is not present at all in the container running DinD service, where it's properly set in job container.
I reproduced your issue by re-using your example in a simplified way:
QUESTION
I am trying to get docker running on Jenkins which itself is a container. Below is part of the Pod spec.
cyrilpanicker/jenkins
is an image with Jenkins and docker-cli installed.
For Docker daemon, I am running another container with docker:dind
image (The nodes are running on a k8s cluster).
And to get docker.sock
linked between them, I am using volume mounts.
ANSWER
Answered 2021-Jun-05 at 14:56According to the kubernetes docs, hostPath
mounts a path from node filesystem, so if I understand correctly, this is not what you want to achieve.
I'm afraid that it isn't possible do mount single file as a volume, so even if you remove hostPath
from volumes
, docker.sock
will be mounted as directory:

separates commands with commands in between. Put your commands as one command, not multiple. Remember they are joined with spaces.
The problem with your script is the colon - see https://gitlab.com/gitlab-org/gitlab-foss/-/issues/30097 .

i am trying to build multiple docker images and push them to my gitlab container registry.
This works just fine, when i build and push them like this:
...ANSWER
Answered 2021-May-19 at 00:50The image ID you build your image with must match the image ID you push. Currently you are trying to push the ID you don't have. Accordingly, you need to tag your image with full id when building, so something along these lines should work:

We have a Gitlab setup with Sysbox (link to the setup) to avoid running the docker executor on priviledged mode. Currently the services
attribute works and we can communicate to it, but containers started with dind
are inaccessible. Here's a minimal .gitlab-ci.yml
file to reproduce the problem:
