Docker powered mini-Heroku. The smallest PaaS implementation you've ever seen.
Assumes Ubuntu 13 right now. Ideally have a domain ready to point to your host. It's designed for and is probably best to use a fresh VM. The bootstrapper will install everything it needs.
$ wget -qO- https://raw.github.com/progrium/dokku/master/bootstrap.sh | sudo bash
This may take around 5 minutes. Certainly better than the several hours it takes to bootstrap Cloud Foundry.
Set up a domain and a wildcard domain pointing to that host. Make sure /home/git/DOMAIN is set to this domain.
By default it's set to whatever the hostname the host has.
You'll have to add a public key associated with a username as it says at the end of the bootstrapper. You'll do something like this from your local machine:
$ cat ~/.ssh/id_rsa.pub | ssh [email protected] "gitreceive upload-key progrium"
That's it!
Right now Buildstep supports buildpacks for Node.js, Ruby, Python, and more. It's not hard to add more, go add more! Let's deploy the Heroku Node.js sample app. All you have to do is add a remote to name the app. It's created on-the-fly.
$ cd node-js-sample
$ git remote add progrium [email protected]:node-js-app
$ git push progrium master

The bootstrap script allows source URLs to be overridden to include customizations from your own repositories. The GITRECEIVE_URL and DOKKU_REPO environment variables may be set to override the defaults (see the bootstrap.sh script for how these apply). Example:
$ wget j.mp/dokku-bootstrap
$ chmod +x bootstrap.sh
$ DOKKU_REPO=https://github.com/yourusername/dokku.git bootstrap.sh
Dokku is in active development. You can update the deployment step and the build step separately. To update the deploy step (this is updated less frequently):
$ cd ~/dokku
$ git pull origin master
$ make install
More frequently, the build step is updated. This is where the app "stack" lives and where buildpacks are supported. You can update this by running:
$ cd ~/dokku/buildstep
$ git pull origin master
$ make build
Nothing needs to be restarted. Changes will take effect on the next push / deployment.
You can use Github Issues, check Troubleshooting on the wiki, or join us on Freenode in #dokku
- Docker - Container runtime and manager
- Buildstep - Buildpack builder
- gitreceive - Git push interface
- sshcommand - Fixed commands over SSH
- Custom domain support for apps
- HTTPS support on default domain
- Support more buildpacks (see Buildstep)
- Use dokku as the system user instead of git
- Heroku-ish commands to be run via SSH (like Dokuen)
Looking to keep codebase as simple and hackable as possible, so try to keep your line count down.
- Multi-host. Not a huge leap, but this isn't the project for it. Maybe as Super Dokku.
- Multitenancy. It's ready for it, but again, probably for Super Dokku.
- Client app. Given the constraints, running commands remotely via SSH is fine.
