Jobs failing with "Cannot connect to the Docker daemon"
The issue was moved to GitLab Runner project at gitlab-runner#4501 (closed). Please move all discussion there.
Summary
CE and EE jobs are are failing with an error like:
docker: Cannot connect to the Docker daemon at tcp://docker:2375. Is the docker daemon running?.
E.g.:
- https://gitlab.com/gitlab-org/gitlab-ee/-/jobs/256902084
- https://gitlab.com/gitlab-org/gitlab-ce/-/jobs/256907818
This is also affecting customers. Presumably it will affect anyone using docker:stable-dind
on our runners.
Update
The runners have been updated with DOCKER_TLS_CERTDIR=""
and so this error should no longer appear on gitlab.com when using GitLab's runners.
