Docker support

[jackblk]

Fun game to play around with!

Currently if we want to selfhost then we need to pull the repo and follow the instructions.

Can we add a docker image to the repo so we can quickly deploy new versions for it?

Also, editing config.ts in this case will not really a good idea. Can we split this config file into a server/client config file, separated from the code files?

For example, we can create serverConfig.json then mount it to the root dir.
