I have recently set up a Docker runner version 15.11.0 with the executor “Docker” on Hetzner and connected it to GitLab’s CI/CD pipeline.
However, I have encountered issues with connecting to specific Docker image repositories, such as GitLab’s.
docker pull registry.gitlab.com/gitlab-org/gitlab-runner/gitlab-runner-helper:x86_64-436955cb
Error response from daemon: Head “https://registry.gitlab.com/v2/gitlab-org/gitlab-runner/gitlab-runner-helper/manifests/x86_64-436955cb”: dial tcp 35.227.35.254:443: i/o timeout
Turns out fix is quite easy:
nano /etc/resolv.conf
Change nameserver to 8.8.8.8:
#nameserver 127.0.0.53
nameserver 8.8.8.8
Enjoy!
