Move to OKD

[Isak-Kallini]

This pr adds a Dockerfile and a github workflow to deploy the website to OKD

This pr will be merged during scheduled downtime on monday 14/4 during the evening starting 17:00 since there are some manual steps needed to move the website over completely:

• Turn off the website when the downtime starts we should turn off the website with pm2 stop to avoid having people use the website and lose data

• Transfer the data to a new database in okd
  as user postgres run

  pg_dump --verbose --no-owner --no-privilege --format=c --blobs "dsek" --file ./data.sql
  

  to create a dump. Then move it to your own home directory and copy it to your local machine with scp:

  scp web-beta.blossm:/path/to/file .
  

  Then copy it to pando:

  scp ./data.sql pando.blossom:/home/is3366ka-s
  

  As root on pando, move it to /klusterbitar/okd/web-db/web-db

  In the OKD web console, go to the terminal of the db pod and navigate to /var/lib/postgresql/data/web-db and run

  pg_restore --clean -U postgres -d dsek data.sql
  

• Make a release In github, make a release as usual and make sure the deployment works correctly

• Point dsek.se to OKD

• Update docs https://cpu.dsek.se/doc/web-4Xyz2sPwYV
