Protected tags (FREE ALL)

Protected tags:

  • Allow control over who has permission to create tags.
  • Prevent accidental update or deletion once created.

Each rule allows you to match either:

  • An individual tag name.
  • Wildcards to control multiple tags at once.

This feature evolved out of protected branches.

Who can modify a protected tag

By default:

  • To create tags, you must have the Maintainer role.
  • No one can update or delete tags.

Configuring protected tags

Prerequisites:

  • You must have at least the Maintainer role for the project.

  1. On the left sidebar, at the top, select Search GitLab ({search}) to find your project.

  2. Select Settings > Repository.

  3. Expand Protected tags.

  4. Select Add new.

  5. To protect a single tag, select Tag, then choose your tag from the dropdown list.

  6. To protect all tags with names matching a string:

    1. Select Tag.
    2. Enter the string to use for tag matching. Wildcards (*) are supported.
    3. Select Create wildcard.

  7. In Allowed to create , select roles that may create protected tags.

    NOTE: In GitLab Premium and Ultimate, you can also add groups or individual users to Allowed to create.

  8. Select Protect.

The protected tag (or wildcard) displays in the Protected tags list.

Wildcard protected tags

You can specify a wildcard protected tag, which protects all tags matching the wildcard. For example:

Wildcard Protected Tag Matching Tags
v* v1.0.0, version-9.1
*-deploy march-deploy, 1.0-deploy
*gitlab* gitlab, gitlab/v1
* v1.0.1rc2, accidental-tag

Two different wildcards can potentially match the same tag. For example, *-stable and production-* would both match a production-stable tag. In that case, if any of these protected tags have a setting like Allowed to create, then production-stable also inherit this setting.

If you select a protected tag's name, GitLab displays a list of all matching tags:

Prevent tag creation with the same name as branches

A tag and a branch with identical names can contain different commits. If your tags and branches use the same names, users running git checkout commands might check out the tag qa when they instead meant to check out the branch qa.

To prevent this problem:

  1. Identify the branch names you do not want used as tags.

  2. As described in Configuring protected tags, create a protected tag:

    • For the Name, provide a name, such as stable. You can also create a wildcard like stable-* to match multiple names, like stable-v1 and stable-v2.
    • For Allowed to Create, select No one.
    • Select Protect.

Users can still create branches, but not tags, with the protected names.

Allow deploy keys to create protected tags

Introduced in GitLab 15.11.

You can permit the owner of a deploy key to create protected tags. The deploy key works, even if the user isn't a member of the related project. However, the owner of the deploy key must have at least read access to the project.

Prerequisites:

  • The deploy key must be enabled for your project. A project deploy key is enabled by default when it is created. However, a public deploy key must be granted access to the project.
  • The deploy key must have write access to your project repository.

To allow a deploy key to create a protected tag:

  1. On the left sidebar, at the top, select Search GitLab ({search}) to find your project.
  2. Select Settings > Repository.
  3. Expand Protected tags.
  4. From the Tag dropdown list, select the tag you want to protect.
  5. From the Allowed to create list, select the deploy key.
  6. Select Protect.

Delete a protected tag

You can manually delete protected tags with the GitLab API, or the GitLab user interface.

Prerequisite:

  • You must have at least the Maintainer role in your project.

To do this:

  1. On the left sidebar, at the top, select Search GitLab ({search}) to find your project.
  2. Select Code > Tags.
  3. Next to the tag you want to delete, select Delete ({remove}).
  4. On the confirmation dialog, enter the tag name and select Yes, delete protected tag.

Protected tags can only be deleted by using GitLab either from the UI or API. These protections prevent you from accidentally deleting a tag through local Git commands or third-party Git clients.
