Try docker dev container

[joepio]

Docker can be used to run development containers. This is especially well integrated with VSCode. This could help new developers get their dev setup up and running. No more hassle with yarn, node, cargo versions and all that - all dev tooling is included in the image.

Unfortunately, I can't seem to run cargo run in the container, as it runs out of memory during fetch:

Updating crates.io index
Killed Fetch [======>                  ]  29.46%, 1.29MiB/s    

I can see the memory limit getting closer (I provided 11GB) and the app crashes when it is reached.

But cargo run should have means to respect memory limits... What's going on here?

Maybe Hitting Container Kernel Memory Limit causes OOM on Docker Host?

Do you want me to look into it? Docker + sccache can speed up re-build. We can also put it into github workflows.

@AlexMikhalev If you feel like it, sure! I have no clue where to find a solution for this. Note that for me there is no direct reason to make this thing work - it's more just something I wanted to play with.

I hadn't even considered that this could speed up build times, but it makes a ton of sense.

I might explore this further, but for now I don't think it has serious advantages over a regular setup.
