hello world :wink:

i’m latest running gitlab (ce) w/ gitlab-runner image on docker host, and while it actually works sometimes, it doesn’t work other times and i can’t figure out why…

gitlab-runner last message when it stops working is:

root@dos:/opt/gitlab-runner# docker-compose logs --tail 1
gitlab-runner-gitlab-runner-1  | WARNING: Checking for jobs... failed                runner=-z4mfftsD status=couldn't execute POST against https://gitlab.X.app/api/v4/jobs/request: Post "https://gitlab.X.app/api/v4/jobs/request": dial tcp 172.20.0.2:443: connect: connection refused
root@dos:/opt/gitlab-runner#

both containers are running within same docker’ network gitlab_default

root@dos:/opt/gitlab-runner# docker network inspect gitlab_default

root@dos:~# uname -a
Linux dos 6.1.0-23-cloud-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.99-1 (2024-07-15) x86_64 GNU/Linux
