This action doesn't delete blobs. To delete them and recycle disk space, run the garbage collection.

Delete registry repository tags in bulk

Delete registry repository tags in bulk based on given criteria.

For an overview, see Use the Container Registry API to delete all tags except *.

DELETE /projects/:id/registry/repositories/:repository_id/tags
Attribute Type Required Description
id integer/string yes The ID or URL-encoded path of the project owned by the authenticated user.
repository_id integer yes The ID of registry repository.
name_regex string no The re2 regex of the name to delete. To delete all tags specify .*. Note: name_regex is deprecated in favor of name_regex_delete. This field is validated.
name_regex_delete string yes The re2 regex of the name to delete. To delete all tags specify .*. This field is validated.
name_regex_keep string no The re2 regex of the name to keep. This value overrides any matches from name_regex_delete. This field is validated. Note: setting to .* results in a no-op.
keep_n integer no The amount of latest tags of given name to keep.
older_than string no Tags to delete that are older than the given time, written in human readable form 1h, 1d, 1month.

This API call performs the following operations:

  • It orders all tags by creation date. The creation date is the time of the manifest creation, not the time of tag push.
  • It removes only the tags matching the given name_regex_delete (or deprecated name_regex), keeping any that match name_regex_keep.
  • It never removes the tag named latest.
  • It keeps N latest matching tags (if keep_n is specified).
  • It only removes tags that are older than X amount of time (if older_than is specified).
  • It schedules the asynchronous job to be executed in the background.

These operations are executed asynchronously and can take time to get executed. You can run this at most once an hour for a given container repository. This action doesn't delete blobs. To delete them and recycle disk space, run the garbage collection.

WARNING: The number of tags deleted by this API is limited on GitLab.com because of the scale of the Container Registry there. If your Container Registry has a large number of tags to delete, only some of them will be deleted, and you might need to call this API multiple times. To schedule tags for automatic deletion, use a cleanup policy instead.

NOTE: In GitLab 12.4 and later, individual tags are deleted. For more details, see the discussion.

Examples:

  1. Remove tag names that are matching the regex (Git SHA), keep always at least 5, and remove ones that are older than 2 days:

    curl --request DELETE --data 'name_regex_delete=[0-9a-z]{40}' --data 'keep_n=5' --data 'older_than=2d' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"

  2. Remove all tags, but keep always the latest 5:

    curl --request DELETE --data 'name_regex_delete=.*' --data 'keep_n=5' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"

  3. Remove all tags, but keep always tags beginning with stable:

    curl --request DELETE --data 'name_regex_delete=.*' --data 'name_regex_keep=stable.*' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"

  4. Remove all tags that are older than 1 month:

    curl --request DELETE --data 'name_regex_delete=.*' --data 'older_than=1month' --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags"
