@rayfordj is this the correct modification for vector where:

• the builder image uses rhel9 and needs the rust compiler
• the final image is to be ubi-micro

There should be an entry in images yml for each FROM in your upstream dockerfile. If you want to keep the upstream AS packages change, then we'll need to add an entry for it:

from:
  builder:
    - member: base-rhel9
    - member: base-rhel9
  stream: rhel9-micro

If instead, you remove the AS packages line to again use a single builder, you should be able to change this COPY to:

COPY --from=builder /mnt/rootfs/ /

for clarity, perhaps keep upstream as you have it and add the additional .from.builder.member in ocp-build-data to align? (Suggested change incoming)
