Chapter 3. Populating your private automation hub container registry

Procedure

1. Log in to Podman using your registry.redhat.io credentials:

   $ podman login registry.redhat.io

   Copy to Clipboard Toggle word wrap
2. Enter your username and password at the prompts.

3. Pull a container image:

   $ podman pull registry.redhat.io/<container_image_name>:<tag>

   Copy to Clipboard Toggle word wrap

Verification

1. List the images in local storage:

   $ podman images

   Copy to Clipboard Toggle word wrap
2. Verify that the image you recently pulled is contained in the list.
3. Verify that the tag is correct.

Verification

1. List the images in local storage:

   $ podman images

   Copy to Clipboard Toggle word wrap
2. Verify that the image you recently tagged with your automation hub information is contained in the list.

Procedure

1. Log in to Podman using your automation hub location and credentials:

   $ podman login -u=<username> -p=<password> <automation_hub_url>

   Copy to Clipboard Toggle word wrap

2. Push your container image to your automation hub container registry:

   $ podman push <automation_hub_url>/<container_image_name> --remove-signatures

   Copy to Clipboard Toggle word wrap
   Note

   The --remove-signatures flag is required when signed images from registry.redhat.io are pushed to the automation hub container registry. The push operation re-compresses image layers during the upload, which is not guaranteed to be reproducible and is client implementation dependent. This may lead to image-layer digest changes and a failed push operation, resulting in Error: Copying this image requires changing layer representation, which is not possible (image is signed or the destination specifies a digest).

Verification

1. Log in to your automation hub.
2. Navigate to Container Registry.
3. Locate the container in the container repository list.
