Configure network and proxy settings

For all self-managed AI features:

  • Your firewalls and HTTP/S proxy servers must allow outbound connections to gitlab.com and cloud.gitlab.com on port 443.
  • Both HTTP2 and the 'upgrade' header must be allowed, because GitLab Duo uses both REST and WebSockets.
  • To use an HTTP/S proxy, both gitLab_workhorse and gitLab_rails must have the necessary web proxy environment variables set.
  • Check for restrictions on WebSocket (wss://) traffic to wss://gitlab.com/-/cable and other .com domains. Network policy restrictions on wss:// traffic can cause issues with some GitLab Duo Chat services. Consider policy updates to allow these services.

Assign seats in bulk

To assign seats in bulk, you can use this GraphQL API endpoint.

This endpoint works for both self-managed and SaaS.

Administrators of self-managed instances can also assign users by using a Rake task.
