Wharf

Wharf is an opinionated web frontend for Dokku. You can also use the command line version, but most features you'll need day-to-day are in the Web UI

Screenshots

Setup

1. Install Dokku (versions up to 0.19.13, see #78)
2. Install the following plugins:
   • https://github.com/dokku/dokku-redis (versions up to 1.10.4, see #75)
   • https://github.com/dokku/dokku-postgres (versions up to 1.9.5, see #75)
   • https://github.com/dokku/dokku-letsencrypt (versions up to 0.9.4 see #115)
3. Setup the Let's Encrypt plugin to auto-renew (dokku letsencrypt:cron-job --add)
4. Create the app (dokku apps:create wharf)
5. Add SSH key storage:
   • mkdir /var/lib/dokku/data/storage/wharf-ssh/
   • chown dokku:dokku /var/lib/dokku/data/storage/wharf-ssh/
   • dokku storage:mount wharf /var/lib/dokku/data/storage/wharf-ssh/:/root/.ssh
6. Add Redis (dokku redis:create wharf && dokku redis:link wharf wharf)
7. Add Postgres (dokku postgres:create wharf && dokku postgres:link wharf wharf)
8. Set ADMIN_PASSWORD to something secret (dokku config:set wharf ADMIN_PASSWORD=somesecret)
9. Deploy this Git repo as per the standard Dokku instructions

Helpful hints

• If you're running SSH on a non-standard port, set DOKKU_SSH_PORT e.g. dokku config:set wharf DOKKU_SSH_PORT=2222
• If Dokku is running somewhere else than the local machine, set DOKKU_SSH_HOST e.g. dokku config:set wharf DOKKU_SSH_HOST=foo.example.com
• If there's a Dockerfile in your repository, it'll try and deploy using that by default. Set BUILDPACK_URL to override
• BUILDPACK_URL should be an HTTPS one, not a SSH or heroku/something one
• You should setup the global domain name when creating Dokku to start with and add a *.<your dokku domain> entry to give new apps more usable names.

Enabling Github auto-deploy webhooks

1. Set GITHUB_SECRET config item to something secret
2. Goto settings/webhooks in Github
3. Make a new webhook for <your Wharf instance>/webhook with Content type as application/json and Secret to the secret from GITHUB_SECRET

Development

Easiest way to do dev is:

1. vagrant up which will boot the entire Dokku setup in a VM
2. DOKKU_SSH_HOST=host.docker.internal DOKKU_SSH_PORT=2222 docker-compose up
   • host.docker.internal works on Mac/Windows, but not on Linux (see https://github.com/docker/for-linux/issues/264). On Linux hosts, you should set DOKKU_SSH_HOST to whatever your IP is (not localhost, but a local IP is fine)
3. Load up http://localhost:8000/
