dokku-daemon

A daemon wrapper around Dokku

Requirements

A VM running Ubuntu 14.04 x64 or later with Dokku v0.4.9 or above installed

Installing

As a user with access to sudo:

git clone https://github.com/dokku/dokku-daemon
cd dokku-daemon
sudo make install

Debian Notes

As a user with access to sudo:

git clone https://github.com/dokku/dokku-daemon
cd dokku-daemon
sudo apt-get install socat
sudo make install

Specifications

• Daemon listens on a UNIX domain socket (by default created at /var/run/dokku-daemon/dokku-daemon.sock)
• Commands issued to the daemon take the same form as those used with dokku on the command-line
• Command names are validated before execution
• Responses are sent as line-delimited JSON
• No authentication layer (local/container connections only)
• Multiple client connections are supported but only one command will be processed at a given time

Example command and response:

< apps:create demo-app
> {"ok":true,"output":"Creating demo-app... done"}

Development

A development environment can be started with the provided Vagrantfile. To start the box and run the test suite:

# on development machine
vagrant up
vagrant ssh

# over vagrant ssh session
cd /dokku-daemon
make test

The executable and init scripts are symlinked to their respective directories rather than copied. To test using Systemd, start Vagrant with environment variable BOX_NAME set to bento/ubuntu-15.04.
