Enabled Git access protocols

Introduced in GitLab 8.10.

With GitLab's access restrictions, you can select with which protocols users can communicate with GitLab.

Disabling an access protocol does not block access to the server itself via those ports. The ports used for the protocol, SSH or HTTP(S), will still be accessible. The GitLab restrictions apply at the application level.

To specify the enabled Git access protocols:

  1. Select the desired Git access protocols from the dropdown:
    • Both SSH and HTTP(S)
    • Only SSH
    • Only HTTP(S)
  2. Click Save changes.

When both SSH and HTTP(S) are enabled, users can choose either protocol.

When only one protocol is enabled:

  • The project page will only show the allowed protocol's URL, with no option to change it.
  • A tooltip will be shown when you hover over the URL's protocol, if an action on the user's part is required, e.g. adding an SSH key, or setting a password.

Project URL with SSH only access

On top of these UI restrictions, GitLab will deny all Git actions on the protocol not selected.

CAUTION: Important: Starting with GitLab 10.7, HTTP(S) protocol will be allowed for Git clone or fetch requests done by GitLab Runner from CI/CD jobs, even if Only SSH was selected.

Custom Git clone URL for HTTP(S)

Introduced in GitLab 12.4.

You can customize project Git clone URLs for HTTP(S). This will affect the clone panel:

Clone panel

For example, if:

  • Your GitLab instance is at https://example.com, then project clone URLs are like https://example.com/foo/bar.git.
  • You want clone URLs that look like https://git.example.com/gitlab/foo/bar.git instead, you can set this setting to https://git.example.com/gitlab/.

Custom Git clone URL for HTTP

To specify a custom Git clone URL for HTTP(S):

  1. Enter a root URL for Custom Git clone URL for HTTP(S).
  2. Click on Save changes.

NOTE: Note: SSH clone URLs can be customized in gitlab.rb by setting gitlab_rails['gitlab_ssh_host'] and other related settings.

RSA, DSA, ECDSA, ED25519 SSH keys

These options specify the permitted types and lengths for SSH keys.

To specify a restriction for each key type:

  1. Select the desired option from the dropdown.
  2. Click Save changes.

For more details, see SSH key restrictions.

Allow mirrors to be set up for projects

Introduced in GitLab 10.3.

This option is enabled by default. By disabling it, both pull and push mirroring will no longer work in every repository and can only be re-enabled by an admin on a per-project basis.
