This includes all the resources currently running on https://gitea.kosmos.org
It sets up a persistent data volume for the MySQL database, one for the
Gitea data, that Gitea calls the custom folder (config, attachment,
avatars, logs, etc). We mount that persistent data volume as
/data/gitea. It also creates a Let's Encrypt certificate for
gitea.kosmos.org, also saved to the custom folder.
This also includes two scripts:
* `./script/get_secrets` downloads the secrets to the local filesystem so
they can be edited
* `./script/replace_secrets` deletes the remote secrets and creates them
again from the local ones in kubernetes/config/*
