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.

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:

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.
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 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: Note: Since GitLab 12.4, individual tags are deleted. For more details, see the discussion.

Examples:

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

bash 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"

Remove all tags, but keep always the latest 5:

bash 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"

Remove all tags that are older than 1 month:

bash 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"
