Description of problem:

Shipwright seems to be creating a `buildah` container inside the build pod but the buildah image used insn't in the release payload

What are customer instructed to do when they use Shipwright in a disconnected env? Are they told to also manually mirror the buildah container image in addition to the release payload?

Prerequisites (if any, like setup, operators/versions):

A disconnected cluster

Steps to Reproduce

1. Have a disconnected cluster
2. Run a Shipwright build
3. If the user didn't mirror the buildah image - is the build pod failing to pull the image?

Actual results:

Expected results:

Ideally, customer should not have any additional step in order to run disconnected envs. Usually they just mirror the release image, create an ITMS,IDMS,ICPS etc.

Reproducibility (Always/Intermittent/Only Once):

Acceptance criteria: 

Definition of Done:

Shipwright, or more specifically buildah, is available out of the box in a disconnected Openshift cluster.
