Getting source containers

Source code is available for all Red Hat UBI-based images in the form of downloadable containers. Here are a few things you should know about Red Hat source containers.

• Although they are packaged as containers, source containers cannot be run. So instead of using podman pull to get them to your system, use the skopeo command.
• Source containers are named based on the binary containers they represent. So, for example, to get the source container for a particular standard RHEL UBI 8 container (registry.access.redhat.com/ubi8/ubi8.1-397) you simply append -source to get the source code container for that image (registry.access.redhat.com/ubi8/ubi8.1-397-source).
• The skopeo command is recommended for getting source containers. With skopeo, you copy a source container to a directory on your local system for you to examine.
• Once a source container is copied to a local directory, you can use a combination of tar,gzip, and rpm commands to work with that content.

Step one

Use skopeo to copy the source image to a local directory

Step two

Inspect the image

Step three

Untar the contents

Step four
