even with the multiple posts over the internet, I can’t figure out how to make my GitLab-Runner working…

I’m using GitLab CE 17.0.0 + 2 GitLab Runners 17.0.0, one hosted on an AlmaLinux 8 server and one hosted on a Windows 11 computer.

Everything worked fine but I would like to set up the Shared Cache.

I’ve set up a MinIO server, hosted on an AlmaLinux 8. GitLab Container Registry is working well with my MinIO server.

Now I would like to set up my GitLab Runners. Both are using Docker executor. Config file are very similar:

concurrent = 1
check_interval = 0
connection_max_age = "15m0s"
shutdown_timeout = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "DELL-Bastien"
  url = "https://gitlab-url"
  id = 19
  token = "..."
  executor = "docker"

  [runners.cache]
    Type = "s3"
    Shared = true

    [runners.cache.s3]
      ServerAddress = "minio-url:9000"
      AccessKey = "..."
      SecretKey = "..."
      BucketName = "gitlab-ci-cache"
      BucketLocation = "eu-east-1"

  [runners.docker]
    tls_verify = false
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["gitlab-pipeline-cache:/cache"]
    shm_size = 0

This configuration is not using my MinIO server as cache server. A Docker volume “gitlab-pipeline-cache” is created and used.

From the runner hosts, if I use the MinIO client, I success to connect to my MinIO server, to upload files, etc. It’s not a network issue.

Thank you!
