第13章 Managing Container Images

With Red Hat Satellite 6, you can import container images from various sources and distribute them to external containers using Content Views.

For information about containers, see Getting Started with Containers in Red Hat Enterprise Linux Atomic Host 7.

13.1. Importing Container Images

You can import container image repositories from Red Hat Registry or from other image registries.

This procedure uses repository discovery to find container images and import them as repositories. For more information about creating a product and repository manually, see 6章Importing Custom Content.

Procedure

To import container image repositories and create or associate them with a product, complete the following steps:

  1. In the Satellite web UI, navigate to Content > Products and click Repo Discovery.
  2. From the Repository Type list, select Container Images.
  3. In the Registry to Discover field, enter the URL of the registry to import images from.
  4. In the Registry Username field, enter the name that corresponds with your user name for the container image registry.
  5. In the Registry Password field, enter the password that corresponds with the user name that you enter.
  6. In the Registry Search Parameter field, enter any search criteria that you want to use to filter your search, and then click Discover.
  7. Optional: To further refine the Discovered Repository list, in the Filter field, enter any additional search criteria that you want to use.
  8. From the Discovered Repository list, select any repositories that you want to import, and then click Create Selected.
  9. Optional: If you want to create a product, from the Product list, select New Product.
  10. In the Name field, enter a product name.
  11. Optional: In the Repository Name and Repository Label columns, you can edit the repository names and labels.
  12. Click Run Repository Creation.
  13. When repository creation is complete, you can click each new repository to view more information.
  14. Optional: To filter the content you import to a repository, click a repository, and then navigate to Limit Sync Tags. Click to edit, and add any tags that you want to limit the content that synchronizes to Satellite.
  15. Navigate to Content > Products and select the name of your product.
  16. Select the new repositories and then click Sync Now to start the synchronization process.

To view the progress of the synchronization navigate to Content > Sync Status and expand the repository tree.

When the synchronization completes, you can click Container Image Manifests to list the available manifests. From the list, you can also remove any manifests that you do not require.

For CLI Users

  1. Create the custom Red Hat Container Catalog product: 

    # hammer product create \
--name "Red Hat Container Catalog" \
--sync-plan "Example Plan" \
--description "Red Hat Container Catalog content" \
--organization "My_Organization"

  2. Create the repository for the container images: 

    # hammer repository create \
--name "RHEL7" \
--content-type "docker" \
--url "http://registry.access.redhat.com/" \
--docker-upstream-name "rhel7" \
--product "Red Hat Container Catalog" \
--organization "My_Organization"

  3. Synchronize the repository: 

    # hammer repository synchronize \
--name "RHEL7" \
--product "Red Hat Container Catalog" \
--organization "My_Organization"
