# Container Registry API **(FREE)**
|
|
|
|
> The use of `CI_JOB_TOKEN` scoped to the current project was [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/49750) in GitLab 13.12.
|
|
|
|
This is the API documentation of the [GitLab Container Registry](../user/packages/container_registry/index.md).
|
|
|
|
When the `ci_job_token_scope` feature flag is enabled (it is **disabled by default**), you can use the below endpoints
|
|
from a CI/CD job, by passing the `$CI_JOB_TOKEN` variable as the `JOB-TOKEN` header.
|
|
The job token will only have access to its own project.
|
|
|
|
[GitLab administrators with access to the GitLab Rails console](../administration/feature_flags.md)
|
|
can opt to enable it.
|
|
|
|
To enable it:
|
|
|
|
```ruby
|
|
Feature.enable(:ci_job_token_scope)
|
|
```
|
|
|
|
To disable it:
|
|
|
|
```ruby
|
|
Feature.disable(:ci_job_token_scope)
|
|
```
|
|
|
|
## Change the visibility of the Container Registry
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/18792) in GitLab 14.2.
|
|
|
|
This controls who can view the Container Registry.
|
|
|
|
```plaintext
|
|
PUT /projects/:id/
|
|
```
|
|
|
|
| Attribute | Type | Required | Description |
|
|
| --------- | ---- | -------- | ----------- |
|
|
| `id` | integer/string | yes | The ID or [URL-encoded path of the project](index.md#namespaced-path-encoding) accessible by the authenticated user. |
|
|
| `container_registry_access_level` | string | no | The desired visibility of the Container Registry. One of `enabled` (default), `private`, or `disabled`. |
|
|
|
|
Descriptions of the possible values for `container_registry_access_level`:
|
|
|
|
- **enabled** (Default): The Container Registry is visible to everyone with access to the project.
|
|
If the project is public, the Container Registry is also public. If the project is internal or
|
|
private, the Container Registry is also internal or private.
|
|
|
|
- **private**: The Container Registry is visible only to project members with Reporter role or
|
|
higher. This is similar to the behavior of a private project with Container Registry visibility set
|
|
to **enabled**.
|
|
|
|
- **disabled**: The Container Registry is disabled.
|
|
|
|
See the [Container Registry visibility permissions](../user/packages/container_registry/index.md#container-registry-visibility-permissions)
|
|
for more details about the permissions that this setting grants to users.
|
|
|
|
```shell
|
|
curl --request PUT "https://gitlab.example.com/api/v4/projects/5/" \
|
|
--header 'PRIVATE-TOKEN: <your_access_token>' \
|
|
--header 'Accept: application/json' \
|
|
--header 'Content-Type: application/json' \
|
|
--data-raw '{
|
|
"container_registry_access_level": "private"
|
|
}'
|
|
```
|
|
|
|
Example response:
|
|
|
|
```json
|
|
{
|
|
"id": 5,
|
|
"name": "Project 5",
|
|
"container_registry_access_level": "private",

|
...
|
|
}
|
|
```
|
|
|
|
## Container Registry pagination
|
|
|
|
By default, `GET` requests return 20 results at a time because the API results
|
|
are [paginated](index.md#pagination).

|
|
| `name_regex` | string | no | The [re2](https://github.com/google/re2/wiki/Syntax) 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](https://github.com/google/re2/wiki/Syntax) regex of the name to delete. To delete all tags specify `.*`. This field is validated. |
|
|
| `name_regex_keep` | string | no | The [re2](https://github.com/google/re2/wiki/Syntax) 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 returns [HTTP response status code 202](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/202)
|
|
if successful, and 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](https://docs.gitlab.com/omnibus/maintenance/index.html#removing-unused-layers-not-referenced-by-manifests).
|
|
|
|
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](../user/packages/container_registry/reduce_container_registry_storage.md#cleanup-policy) instead.
|
|
|
|
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:
|
|
|
|
```shell
|
|
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"
|
|
```
|
|
|
|
1. Remove all tags, but keep always the latest 5:
|
|
|
|
```shell
|
|
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"
|
|
```
|
|
|
|
1. Remove all tags, but keep always tags beginning with `stable`:
|
|
|
|
```shell
|
|
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"
|
|
```
|
|
|
|
1. Remove all tags that are older than 1 month:
|
|
|
|
```shell
|
|
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"
|
|
```
|
|
|
|
## Instance-wide endpoints
|
|
|
|
Beside the group- and project-specific GitLab APIs explained above,
|
|
the Container Registry has its own endpoints.
|
|
To query those, follow the Registry's built-in mechanism to obtain and use an
|
|
[authentication token](https://docs.docker.com/registry/spec/auth/token/).
|
|
|
|
NOTE:
|
|
These are different from project or personal access tokens in the GitLab application.
|
|
|
|
### Listing all container repositories
|
|
|
|
```plaintext
|
|
GET /v2/_catalog
|
|
```
|
|
|
|
To list all container repositories on your GitLab instance, administrator credentials are required:
|
|
|
|
```shell
|
|
$ curl --request GET --user "<admin-username>:<admin-password>" "https://gitlab.example.com/jwt/auth?service=container_registry&scope=registry:catalog:*"
|
|
{"token":" ... "}
|
|
|
|
$ curl --header "Authorization: Bearer <token_from_above>" https://gitlab.example.com:5050/v2/_catalog
|
|
{"repositories":["user/project1", "group/subgroup/project2", ... ]}
|
|
```
|
