Ignore docker-compose.override.yml

[alanivey]

Allow for overrides of docker-compose.yml without impacting git status.

@alanivey I'm curious, what are you typically overriding?

[alanivey]

Setting logging for each service to send logs to Amazon CloudWatch, and making all named and anonymous volumes bind mounts to local directories for a few reasons (ease of backing up and restoring, being able to down+up the containers without losing LE certs)

@alanivey Thanks for clarifying. I didn't know about docker-compose.override.yml and it's super helpful! If you come across other Docker best-practices that would be broadly useful to bake into Central, please do file issues.

@lognaturel This seems like a great change to me. It's a known convention.

Thanks, @alanivey, this is great. I've also filed a follow-up docs issue: getodk/docs#1616
