Automate building and running base image on RPi with Docker CLI

[hhenry01]

Purpose

Our RPi needs to operate without a GUI, and just needs to run our software. Dedicated scripting to build and run will make the process a lot faster.

Changes

New script(s) to build the container, run it, and also execute a list of programs when given the paths/commands (a default to run all software should also be defined).

Adapted from #79 (comment)

Another solution to evaluate against building on RPi is to build in CI:

• Add workflow to push built image: clones repos and builds them
  • From base image
  • Runs on push to main and pull request
  • Tag is commit hash
    • Can also use latest tag to quickly test changes that you make

Upside is that you don't have to build or develop on RPi. Downside is that it may take a couple minutes for the images to be built and pushed.

If we build on the RPi, we can clone sailbot_workspace locally and make it a volume when running the base image, effectively making our own dev container

• Setup Docker on Rpi
• See how long it takes to build compared to x86 laptop
• Decide on path forwards: build locally, CI, or on x86 laptop?

Build Times

Ran setup, clean, and build tasks with network_systems, py_pubsub_ex, and cpp_pubsub_ex,

Computer	Build Time	CPU	Memory	Architecture	OS	Other Notes
XPS 15	30s	i7-12700H	32 GB	x86	Windows
Lenovo C940	50s	i7-1065G7	16 GB	x86	Windows
Lenovo C940	50s	i7-1065G7	16 GB	x86	Ubuntu	Used Docker Desktop which runs in a VM, Docker Engine may be faster
Gigabyte G5 MD	30s	i5-11400H	16GB	x86	Pop OS
Macbook Pro 14	30s	M1 Pro	16 GB	arm	MacOS
Macbook Air	120s	M1	8 GB	arm	MacOS	Memory was bottleneck: even before running docker memory was full, peaked at 11GB swap

@hhenry01 do you have docker engine or desktop installed on popos? Can you add your build times?

Docker engine. Added.
