Deletion protection

DETAILS: Tier: Premium, Ultimate Offering: Self-managed

• Introduced in GitLab 14.2 for groups created after August 12, 2021.
• Renamed from default delayed project deletion in GitLab 15.1.
• Enabled for projects in personal namespaces in GitLab 15.1.
• Disabled for projects in personal namespaces in GitLab 15.3.
• Removed option to delete immediately in GitLab 15.11 with a flag named always_perform_delayed_deletion. Disabled by default.
• Enabled delayed deletion by default and removed the option to delete immediately on GitLab.com and on self-managed in GitLab 16.0.

Instance-level protection against accidental deletion of groups and projects.

Retention period

• Changed in GitLab 15.1.

Groups and projects remain restorable within a defined retention period. By default this is 7 days but it can be changed. Setting the retention period to 0 means that groups and project are removed immediately and cannot be restored.

In GitLab 15.1 and later, the retention period must be between 1 and 90. If the retention period was 0 before the 15.1 update, then it gets automatically changed to 1 while also disabling deletion protection the next time any application setting is changed.

Delayed project deletion

• User interface changed in GitLab 15.1.
• Enabled delayed deletion by default and removed the option to delete immediately on GitLab.com and on self-managed in GitLab 16.0.

To configure delayed project deletion:

1. Sign in to GitLab as a user with administrator access.
2. On the left sidebar, at the bottom, select Admin Area.
3. Select Settings > General.
4. Expand the Visibility and access controls section.
5. Scroll to:
   • In GitLab 16.0 and later: Deletion protection and set the retention period to a value between 1 and 90.
   • In GitLab 15.11 with always_perform_delayed_deletion feature flag enabled: Deletion protection and set the retention period to a value between 1 and 90.
   • In GitLab 15.1 to 15.10: Deletion protection and select Keep deleted groups and projects, then set the retention period.
   • In GitLab 15.0 and earlier: Default delayed project protection and select Enable delayed project deletion by default for newly-created groups, then set the retention period.
6. Select Save changes.

Deletion protection is not available for projects only (without being also being enabled for groups).

In GitLab 15.1, and later this setting is enforced on groups when disabled and it cannot be overridden.

Delayed group deletion

• User interface introduced in GitLab 15.1.
• Changed to default behavior on the Premium and Ultimate tier in GitLab 16.0.

Groups remain restorable if the retention period is 1 or more days.

In GitLab 15.1 and later, delayed group deletion can be enabled by setting Deletion projection to Keep deleted. In GitLab 15.11 and later with the always_perform_delayed_deletion feature flag enabled, or in GitLab 16.0 and later:

• The Keep deleted option is removed.
• Delayed group deletion is the default.

Override defaults and delete immediately

Alternatively, projects that are marked for removal can be deleted immediately. To do so:

1. Restore the project.
2. Delete the project as described in the Administering Projects page.

Configure project visibility defaults

For more details on group visibility, see Group visibility.

Restrict visibility levels

• Changed in GitLab 16.3 to prevent restricting default project and group visibility, with a flag named prevent_visibility_restriction. Disabled by default.
• prevent_visibility_restriction enabled by default in GitLab 16.4.
• The flag prevent_visibility_restriction was removed in GitLab 16.7.

When restricting visibility levels, consider how these restrictions interact with permissions for subgroups and projects that inherit their visibility from the item you're changing.

To restrict visibility levels for groups, projects, snippets, and selected pages:

1. Sign in to GitLab as a user with Administrator access level.
2. On the left sidebar, at the bottom, select Admin Area.
3. Select Settings > General.
4. Expand the Visibility and access controls section.
5. In the Restricted visibility levels section, select the desired visibility levels to restrict.
   • If you restrict the Public level:
     • Only administrators are able to create public groups, projects, and snippets.
     • User profiles are only visible to authenticated users through the Web interface.
     • User attributes through the GraphQL API are:
       • Not visible in GitLab 15.1 and later.
       • Only visible to authenticated users between GitLab 13.1 and GitLab 15.0.
   • If you restrict the Internal level:
     • Only administrators are able to create internal groups, projects, and snippets.
   • If you restrict the Private level:
     • Only administrators are able to create private groups, projects, and snippets.
6. Select Save changes.

NOTE: You cannot select the restricted default visibility level for new projects and groups.

Configure enabled Git access protocols

With GitLab access restrictions, you can select the protocols users can use to communicate with GitLab. Disabling an access protocol does not block port access to the server itself. The ports used for the protocol, SSH or HTTP(S), are still accessible. The GitLab restrictions apply at the application level.

To specify the enabled Git access protocols:

1. Sign in to GitLab as a user with Administrator access level.
2. On the left sidebar, at the bottom, select Admin Area.
3. Select Settings > General.
4. Expand the Visibility and access controls section.
5. Select the desired Git access protocols:
   • Both SSH and HTTP(S)
   • Only SSH
   • Only HTTP(S)
6. Select Save changes.

When both SSH and HTTP(S) are enabled, users can choose either protocol. If only one protocol is enabled:

• The project page shows only the allowed protocol's URL, with no option to change it.

• GitLab shows a tooltip when you hover over the protocol for the URL, if user action (such as adding a SSH key or setting a password) is required:

  

GitLab only allows Git actions for the protocols you select.

WARNING: GitLab 10.7 and later allows the HTTP(S) protocol for Git clone or fetch requests performed with GitLab CI/CD job tokens, even if you select Only SSH. This is required for GitLab Runner and CI/CD jobs.

Customize Git clone URL for HTTP(S)

• Introduced in GitLab 12.4.

You can customize project Git clone URLs for HTTP(S), which affects the 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/.

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

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

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

Configure defaults for RSA, DSA, ECDSA, ED25519, ECDSA_SK, ED25519_SK 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 list.
2. Select Save changes.

For more details, see SSH key restrictions.

Enable project mirroring

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

Configure globally-allowed IP address ranges

• Introduced in GitLab 15.1 with a flag named group_ip_restrictions_allow_global. Disabled by default.
• Generally available in GitLab 15.4. Feature flag group_ip_restrictions_allow_global removed.

Administrators can set IP address ranges to be combined with group-level IP restrictions. Use globally-allowed IP addresses to allow aspects of the GitLab installation to work even when group-level IP address restrictions are set.

For example, if the GitLab Pages daemon runs on the 10.0.0.0/24 range, you can specify that range as globally-allowed. This means GitLab Pages can still fetch artifacts from pipelines even if group-level IP address restrictions don't include the 10.0.0.0/24 range.

To add a IP address range to the group-level allowlist:

1. Sign in to GitLab as a user with Administrator access level.
2. On the left sidebar, at the bottom, select Admin Area.
3. Select Settings > General.
4. Expand the Visibility and access controls section.
5. In Globally-allowed IP ranges, provide a list of IP address ranges. This list:
   • Has no limit on the number of IP address ranges.
   • Has a size limit of 1 GB.
   • Applies to both SSH or HTTP authorized IP address ranges. You cannot split this list by type of authorization.
6. Select Save changes.
