I’ve set up a new gitlab-runner on my homelab GitLab server. It’s using a Docker executer, and when it attempts to pull the repo to build, it’s gets error:
Could not resolve host: gitlab.local (Domain name not found)
gitlab.local is in /etc/hosts on the VM and I can ping the name and it resolves. A quick Google found this post, and the suggestion is to edit /etc/gitlab-runner/config.toml and add:
network_mode = "host"
to the [runners.docker] section. Seems like that fixes the issue.
