Control GitLab Duo availability

• Settings to turn off AI features introduced in GitLab 16.10.
• Settings to turn off AI features added to the UI in GitLab 16.11.

GitLab Duo features that are generally available are automatically turned on for all users that have access. In addition:

• If you have self-managed GitLab, you must allow connectivity.
• If you have GitLab Dedicated, you must have GitLab Duo Pro or Enterprise.
• For some generally available features, like Code Suggestions, you must assign seats to the users you want to have access.

GitLab Duo features that are experimental or beta are turned off by default and must be turned on.

Configure GitLab Duo on a self-managed instance

To use GitLab Duo on a self-managed instance, you must ensure connectivity exists.

Allow outbound connections from the GitLab instance

• Your firewalls and HTTP/S proxy servers must allow outbound connections to cloud.gitlab.com and customers.gitlab.com on port 443 both with https://.
• To use an HTTP/S proxy, both gitLab_workhorse and gitLab_rails must have the necessary web proxy environment variables set.

Allow inbound connections from clients to the GitLab instance

• GitLab instances must allow inbound connections from Duo clients (IDEs, Code Editors, and GitLab Web Frontend) on port 443 with https:// and wss://.
• Both HTTP2 and the 'upgrade' header must be allowed, because GitLab Duo uses both REST and WebSockets.
• Check for restrictions on WebSocket (wss://) traffic to wss://gitlab.example.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.

Turn off GitLab Duo features

You can turn off GitLab Duo for a group, project, or instance.

When GitLab Duo is turned off for a group, project, or instance:

• GitLab Duo features that access resources, like code, issues, and vulnerabilities, are not available.
• Code Suggestions are not available.

However, GitLab Duo Chat works differently. When you turn off GitLab Duo:

• For a group or project:

  • You can still ask questions of GitLab Duo Chat. These questions must be generic, like asking about GitLab or asking general questions about code. GitLab Duo Chat will not access group or project resources, and will reject questions about them.

• For an instance:

  • The GitLab Duo Chat button is not available anywhere in the UI.
