Docker container switching to debian slim in 1.2.2 breaks installation of common db related packages

Hi,
Apologies in advance, I'm not sure if these are even distributed by you (bit of hunting couldn't tell me conclusively one way or the other) - but thought it was best to flag here.

The new 1.2.2 docker image (https://hub.docker.com/layers/dotnetroundhouse/roundhouse/1.2.2/images/sha256-854467d4535d80a2cb929607427458f9bcabff6585e04570a9c5ce50b0c4655d?context=explore) has broken our build this morning as its not possible to install the debian postgresql-client package on it. I assume this is because it has been switched to use debian-slim as a base image in order to reduce the overall distribution size.

Right now I've just pinned our build back to 1.0.2 to avoid the problem, as my quick workarounds (debuerreotype/debuerreotype#10) weren't working and I need to get on with other things. Not sure what you see as being the solution to this? I would say the expectation of installing postgresql-client is reasonable (we use it with a bootstrap script to make sure databases exist and to optionally drop them before running roundhouse in order to build and destroy QA environments quickly).

Cheers,
Kieran

Hmmm... thanks for the report. Yes, it's me making the docker images, and here I thought I had been so clever... terribly sorry to break you setup.

So, just to understand better, you use the roundhouse docker image as a base image, creating a new image putting your own stuff on it (including the postgres-client)?

Have you tried the workaround in the issue you referenced? Does adding this line to your Dockerfile solve your problem?

Not a problem! It looked like a reasonable change to make - library is brilliant as well btw.

Yes, that's exactly the case - using the image as a base and adding a couple of things to it (principally just the postgres-client).

I did try the workaround, and whilst I only spent an hour on it I couldn't get it to work so moved on. No obvious reason why it wasn't, was consistently getting the same error.

Then I pinned the base image version back as I say and I was back in business.

I think I'll close this one, as it's not a problem with roundhouse per se, but a problem/feature of the debian-slim image that makes it difficult to run Postgreql on it
