Manage users in the Container Registry

Open the Users tab to view the following information about created users within your Container Registry:

  • The date and time when the user was created

  • (Optional) If the password expiration date was set during user creation, this information will be displayed in the Expires at column.

You can change user permissions, generate a new user password, or delete the user from the registry.

For details on how to create a user, check the Create a Container Registry guide.

Change user permissions

For each user, you can configure the following permissions:

  • Pull images: this is helpful if you’d like to prevent unauthorized or accidental changes to the Container Registry. In this case, you can restrict permissions for some users to pull operations only.

  • Push and push images: this permission grants full access to the registry and allows users to pull and push any new images or image versions to the registry.

To change user permissions:

1. On the Users tab, find the user you want to delete and click the three-dot icon next to it.

2. Select Change permissions.
