Delete a registry repository tag

Delete a registry repository tag.

DELETE /projects/:id/registry/repositories/:repository_id/tags/:tag_name
AttributeTypeRequiredDescription
idinteger/stringyesThe ID or URL-encoded path of the project owned by the authenticated user.
repository_idintegeryesThe ID of registry repository.

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 registry repository tags in bulk

Delete registry repository tags in bulk based on given criteria.

DELETE /projects/:id/registry/repositories/:repository_id/tags
AttributeTypeRequiredDescription
idinteger/stringyesThe ID or URL-encoded path of the project owned by the authenticated user.
repository_idintegeryesThe ID of registry repository.
name_regexstringnoThe re2 regex of the name to delete. To delete all tags specify .*. Note: name_regex is deprecated in favor of name_regex_delete.
name_regex_deletestringyesThe re2 regex of the name to delete. To delete all tags specify .*.
name_regex_keepstringnoThe re2 regex of the name to keep. This value will override any matches from name_regex_delete. Note: setting to .* will result in a no-op.
keep_nintegernoThe amount of latest tags of given name to keep.
older_thanstringnoTags 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_delete (or deprecated name_regex), keeping any that match name_regex_keep.
  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: Since GitLab 12.4, 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"
