I'm encountering an issue with GitLab's Kubernetes Agent Server (GitLab-KAS) on my DigitalOcean droplet running GitLab-CE.

Despite attempts to restart and reconfigure GitLab, the GitLab-KAS service remains down, causing a failure in my GitLab instance.

I've also made several modifications to the gitlab.rb configuration file but with no success.

Goal: Can anyone suggest how to troubleshoot and resolve the GitLab-KAS service failure on my DigitalOcean droplet to get my GitLab up and running for everyone else?

Current Status: When I run sudo gitlab-ctl status, I get the following output:

down: gitlab-kas: 0s, normally up, want up

Attempts made:

  • I tried disabling GitLab-KAS by setting gitlab_kas['enable'] = false in gitlab.rb.

While this prevents the service from starting and does not show up in gitlab-ctl status, it doesn't resolve the issue, and I don't receive any response in the UI.

  • I also attempted to configure the external URL for GitLab-KAS by adding gitlab_kas_external_url "wss://gitlab.company.com/-/kubernetes-agent/", but GitLab-KAS remains down.
  • Additionally, I tried enabling GitLab-KAS with the following configurations in gitlab.rb: gitlab_kas['internal_api_listen_network'] = 'unix' gitlab_kas['internal_api_listen_address'] = '/var/opt/gitlab/gitlab-kas/sockets/internal-api.socket' gitlab_kas['private_api_listen_network'] = 'unix' gitlab_kas['private_api_listen_address'] = '/var/opt/gitlab/gitlab-kas/sockets/private-api.socket' gitlab_kas['env'] = { 'SSL_CERT_DIR' => "/opt/gitlab/embedded/ssl/certs/", 'OWN_PRIVATE_API_URL' => 'unix:///var/opt/gitlab/gitlab-kas/sockets/private-api.socket' }

However, this also didn't resolve the issue.

If you don't use Kubernetes, GitLab-KAS can be disabled:

  • In gitlab.rb, set gitlab_kas['enable'] = false
  • Update and restart using gitlab-ctl reconfigure
  • Check all is OK with gitlab-ctl status

This is necessary for anyone who has just upgraded their GitLab-CE (Community Edition) to V17 in a simple VM (no Kubernetes) who finds their pipelines not working (because GitLab-KAS is enabled by default).
