Push an image

Push images to Harbor for enhanced security with role-based access control, automated vulnerability scanning, and simplified image management for your containerized applications. To push a local image to a Harbor instance, tag it with the repository name and then push the image.

Before you begin

To push an image to Harbor, you must have access to the following:

  • The necessary identity and access role. Ask your Organization IAM Admin to grant you the Harbor Instance Viewer (harbor-instance-viewer) role.
  • An account with the Developer role from Harbor's role-based access controls. For more information, see Configure access for APIs and within a Harbor instance.
  • An existing Harbor project. For more information, see Create Harbor projects.

Tag the local image

Follow these steps to tag a local image with the repository name:

  1. You must be authenticated to the Harbor instance. For more information, see Configure Docker authentication to Harbor registry instances.

  2. Set the name of the image. The format of a full image name is:

    INSTANCE_URL/HARBOR_PROJECT_NAME/IMAGE

    Replace the following:

    • INSTANCE_URL: the URL of the Harbor instance. For example, harbor-1.org-1.zone1.google.gdc.test. Get the URL of the Harbor instance using GDC console or gdcloud CLI.
    • HARBOR_PROJECT_NAME: the name of the Harbor project. For example, my-project.
    • IMAGE_NAME: the image's name. For example, nginx.

    An example of the full image name might look like the following:

    harbor-1.org-1.zone1.google.gdc.test/my-project/nginx

  3. Tag the local image with the repository name:

    docker tag SOURCE-IMAGE
INSTANCE_URL/HARBOR_PROJECT_NAME/IMAGE:TAG

Replace the following:

  • SOURCE-IMAGE: the local image name or image ID. For example, nginx.
  • TAG: the tag name. For example, staging. If you don't specify a tag, Docker applies the latest tag by default.

Push the tagged image to a Harbor registry instance

After the image is tagged, push it to the Harbor registry instance:

  1. Make sure that you are authenticated to the Harbor instance.
  2. Push the tagged image with the command:
docker push
INSTANCE_URL/HARBOR_PROJECT_NAME/IMAGE:TAG

When you push an image, it is stored in the specified instance and Harbor project.

After pushing your image, go to the Harbor instance UI to view the image.
