Can you be more precise about what is being "fixed"? I thought that we had some strange situation where either blob depending on backup, or backup depended on blob... but looking at the "before" state here, I can't seem to find where that dependency is...

I edited the revision's title.

Good idea. There are a couple other improvements possible now, in particular building gRPC with the -DgRPC_SSL_PROVIDER=package and -DgRPC_ZLIB_PROVIDER=package flags to avoid building BoringSSL and rebuilding zlib and instead use the system libs installed in the base image.

services/backup/docker-base/Dockerfile
7 ↗	(On Diff #10012)	Moving this into a separate RUN command defeats the whole point, which is to avoid having a layer with the whole apt cache. See https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get "In addition, when you clean up the apt cache by removing /var/lib/apt/lists it reduces the image size, since the apt cache is not stored in a layer."

Huh? It's confusing to read this. In D3198 you clearly indicate that the confusing dependency is not addressed – in fact, in that diff you created a Linear task to track that issue (on my request).

But now you seem to be indicating that that diff solves the confusing dependency?

Honestly, I think the reason for my continued confusion is that you responded to my request to be "more precise" with a total of 12 words. Can you please try again, and this time explain in detail an answer to my question?

Here's the question again:

I thought that we had some strange situation where either blob depending on backup, or backup depended on blob... but looking at the "before" state here, I can't seem to find where that dependency is...

Where is the dependency? Does it still exist?

Requesting changes for @jimpo's comment. @karol-bisztyga, I'm pretty sure that the issues around build caching in Docker and the reasoning for merging these RUN commands has been discussed before in diffs that you have been on. See my comment here – it's concerning to me that you missed that whole discussion, and then made this change without doing the appropriate research

Here I said:

I'm going to push here some changes that get rid of it and an additional diff that follows the DRY rule.

And by "it" I meant this confusing dependency, this was said in D3198. So, once again:

in D3198 I get rid of the confusing dependency
here I get rid of repeated stuff in the Dockerfiles

I see now that the description in this task was probably misleading so I updated it.

I hope it's now all clear, I'm not sure what else I can say to put yet more light on this, it looks pretty straightforward to me.

Yes, this is an oversight on my end, sorry, I'm going to fix this. @jimpo thanks for clarifying and catching this!

Is there a task for this?

Thanks for this explanation – I understand now!!
