Context: RHDHSUPP-309

• Docker image at .rhdh/docker/Dockerfile#L233-L260
  • Calls install-dynamic-plugins.py at runtime to install plugins defined by configmap (can't be done earlier at build time)
  • depends on python and skopeo, currently

Ideas:

• switch from skopeo to podman? See gist for approach
• replace skopeo with native nodejs or bash calls that can inspect a registry and fetch a tarball
  • replacement for skopeo inspect - see this python method
  • replacement for skopeo copy ... unknown at this time

• replace python script with nodejs or bash script entirely

GOAL:

• smaller container image
• smaller attack surface for CVEs
• fewer RPMs to manage in the containerfile
