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 the Let's Encrypt plugin to auto-renew (dokku letsencrypt:cron-job --add)
Create the app (dokku apps:create wharf)
Add SSH key storage:

Add Redis (dokku redis:create wharf && dokku redis:link wharf wharf)
Add Postgres (dokku postgres:create wharf && dokku postgres:link wharf wharf)
Set ADMIN_PASSWORD to something secret (dokku config:set wharf ADMIN_PASSWORD=somesecret)
Deploy this Git repo as per the standard Dokku instructions

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.

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

Easiest way to do dev is:

vagrant up which will boot the entire Dokku setup in a VM
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 docker/for-linux#264). On Linux hosts, you should set DOKKU_SSH_HOST to whatever your IP is (not localhost, but a local IP is fine)
Load up http://localhost:8000/
