Add dev convenience script for building containers

[asavageiv]

A small script to make building the containers for local dev testing a little easier:

Usage: ./scripts/build-containers.sh [--variant develop|beta] <container1> [container2] [container3] ...
Example: ./scripts/build-containers.sh --variant beta apache mastercontainer

Feel free to reject this if there's a better way.

Hi I am not sure about adding this to the repo as we would also need to maintain it then. Wdyt @pabzm?

[pabzm]

I don't need this script, but also wouldn't mind it – but I'd also prefer to only include such scripts if multiple devs or contributors would like to use it.

Out of curiousity, how do you all build the containers when doing local dev? Do you just type it out every time or use shell history? Maybe I am doing it wrong.

[asavageiv]

The idea is loosely based on this:
https://github.blog/engineering/scripts-to-rule-them-all/

I use docker devcontainers heavily so I'm often spinning up a clean environment with no shell history.

I don't do it often, usually work with the images built in the CI.

Why do you build them locally?

[asavageiv]

I build them locally for faster iteration. Do you make a commit and push to CI before doing any testing or are you editing directly inside of running containers? My flow was:

1. Make edits to the code
2. Build appropriate containers with appropriate tags (sometimes push the image to a remote machine, depending on where I'm doing the editing vs where the containers are running)
3. Stop and start the containers with bypass_container_update/mastercontainer_update
4. Do testing

Sometimes I would make edits directly in the container then copy them back to my source code directory.
I tried out bind-mounting some directories into containers, but permissions got tricky.

errors and warnings should echo to >&2

what about adding a help text when users pass in -h ?
