People have been having issues with this. I copied it from
`docker/stable-ubuntu.Dockerfile`. We should follow up on this to remove
the duplication at some point but this will help fix the problems people
are having now.
- The `:edge` and `:edge-alpine` containers will now download the latest
commit of the frontend repo and build it when they are built.
- The backend dependency install process now uses the local copy of Yarn
(from #56) to install dependencies
- Extraneous files are no longer copied into the production image. This
is mostly a win for local builds (where the `.yarn` cache folder used to
get copied in) but it’s also a small win for CI-built containers which
will no longer have the README/configuration files/Yarn source code
lying around
- The dockerfiles now say `EXPOSE 5006`. This doesn’t have an effect on
anything by default as far as I can tell but it does mean that tools
know we will be listening on that port and can help users set up their
container accordingly (for example, Docker Desktop)
- Remove some extraneous dependencies from the containers (including
openssl)
