Container Registry API

The use of CI_JOB_TOKEN scoped to the current project was introduced in GitLab 13.12.

This is the API documentation of the GitLab Container Registry.

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 can opt to enable it.

To enable it:

Feature.enable(:ci_job_token_scope)

To disable it:

Feature.disable(:ci_job_token_scope)

Change the visibility of the Container Registry

Introduced in GitLab 14.2.

This controls who can view the Container Registry.

PUT /projects/:id/
Attribute Type Required Description
id integer/string yes The ID or URL-encoded path of the project 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 for more details about the permissions that this setting grants to users.

Example response:

{
  "id": 5,
  "name": "Project 5",
