tutum-agent

What's this?

This is the agent Tutum uses to set up nodes. It's a daemon that will register the host with the Tutum API using a user token (TutumToken), and will manage the installation, configuration and ongoing upgrade of the Docker daemon.

For information on how to install it in your host, please check the Bring Your Own Node documentation.

Running

If installing from a .deb or .rpm package, Tutum Agent will be configured in upstart to be launched on boot.

# tutum-agent -h
Usage of ./tutum-agent:
  -debug=false: Enable debug mode
  -docker-host="": Override 'DockerHost'
  -docker-opts="": Add additional flags to run docker daemon
