Chapter 5. Using Red Hat Quay

Procedure

1. To test pushing and pulling images from the Red Hat Quay registry, first pull a sample image from an external registry:

   $ sudo podman pull busybox

   Example output

   Trying to pull docker.io/library/busybox...
   Getting image source signatures

   Copying config 22667f5368 done

2. Enter the following command to see the local copy of the image:

   $ sudo podman images

   Example output

   REPOSITORY                          TAG      IMAGE ID       CREATED         SIZE
   docker.io/library/busybox           latest   22667f53682a   14 hours ago    1.45 MB

3. Enter the following command to tag this image, which prepares the image for pushing it to the registry:

   $ sudo podman tag docker.io/library/busybox quay-server.example.com/quayadmin/busybox:test

4. Push the image to your registry. Following this step, you can use your browser to see the tagged image in your repository.

   $ sudo podman push --tls-verify=false quay-server.example.com/quayadmin/busybox:test

   Example output

   Getting image source signatures
   Copying blob 6b245f040973 done
   Copying config 22667f5368 done
   Writing manifest to image destination
   Storing signatures

5. To test access to the image from the command line, first delete the local copy of the image:

   $ sudo podman rmi quay-server.example.com/quayadmin/busybox:test
   Untagged: quay-server.example.com/quayadmin/busybox:test

6. Pull the image again, this time from your Red Hat Quay registry:

   $ sudo podman pull --tls-verify=false quay-server.example.com/quayadmin/busybox:test

   Example output

   Trying to pull quay-server.example.com/quayadmin/busybox:test...
