When I try the instructions for "Adjusting an image" with `docker-pkg update` in the releng/dev-images repo, I get:

❯ docker-pkg -c dockerfiles/config.yaml --info update --reason "Add php-ast package (T246386)" --version 0.1.0 stretch-php72 dockerfiles/

== Step 0: scanning {d}

@Jdforrester (WMF) any ideas?

Huh. Not really; just tried that locally and it works fine.

This is the CI build system. It uses docker-registry.wikimedia.org/releng/ as the default prefix, so maybe that's an issue? But then, why would it work locally? Are you trying to revise wikimedia-stretch and use an unpublished version of that?

I was trying to add the php-ast package to stretch-php72 in the releng/dev-images repo. I assumed that the update command would then allow all the images which depend on that one to get updated. Am I misusing this command?

Yes. It doesn't work cross-repo; you have to make the changes in releng/dev-images, merge them, publish the images, and then re-build the images in that repo.

I wonder if https://gerrit.wikimedia.org/r/plugins/gitiles/releng/dev-images/+/master/dockerfiles/stretch/control#1 is the problem?

That should cascade through, though? The dev-images build starts from / not /releng? Or am I mis-remembering?
