Create docker container. (#217)

* Create docker container.

Commands run (no changes):

1. `bundle add dockerfile-rails --optimistic --group development`
1. `bin/rails generate dockerfile --nginx --parallel`
1. `rm -rf .yarn`
1. `rm .yarnrc`
1. Copy build+publish action from DPUL-C

* Rubocop.

* Too many vulns, use a more recent image.

* Only scan OS vulnerabilities

We have dependabot for libraries.

* Add staging HCL

* Podman.

* Add docker compose.

There was a missing pids directory that was necessary for launching -
this docker-compose file let me debug that.

* Go back to accurate ruby version.

* Production HCL.

* Only use env variable if necessary.

* Update ruby.

* Set resource requirements.

* Add nightly vuln scan.

* Add spreading.
