It's dokku, we need to follow dokku's deployment guide The absolute bare minimum is a procfile, e.g. https://github.com/galaxyproject/ptdk/blob/main/Procfile and then we setup the git remote to push to the right host. There's a deployment script we can copy-paste: https://github.com/hexylena/gtn-slack-bot/blob/main/.github/workflows/deploy.yml
