Delete a repository tag

Delete a registry repository tag.

DELETE /projects/:id/registry/repositories/:repository_id/tags/:tag_name
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.
tag_name string yes The name of tag.
curl --request DELETE --header "PRIVATE-TOKEN: <your_access_token>" "https://gitlab.example.com/api/v4/projects/5/registry/repositories/2/tags/v10.0.0"

This action does not delete blobs. In order to delete them and recycle disk space, run the garbage collection.

Delete repository tags in bulk

Delete repository tags in bulk based on given criteria.

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 yes The regex of the name to delete. To delete all tags specify .*.
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:

  1. It orders all tags by creation date. The creation date is the time of the manifest creation, not the time of tag push.
  2. It removes only the tags matching the given name_regex.
  3. It never removes the tag named latest.
  4. It keeps N latest matching tags (if keep_n is specified).
  5. It only removes tags that are older than X amount of time (if older_than is specified).
  6. It schedules the asynchronous job to be executed in the background.

These operations are executed asynchronously and it might take time to get executed. You can run this at most once an hour for a given container repository. This action does not delete blobs. In order to delete them and recycle disk space, run the garbage collection.

Note: Due to a Docker Distribution deficiency, it doesn’t remove tags whose manifest is shared by multiple tags.

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=[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=.*' --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 that are older than 1 month:

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