Installing Paz on Bare Metal

Paz works fine on a bare metal install, but there is no installation script available for it yet.

You need to create your cluster, then add the contents of bare_metal/user-data to your cloud config, and finally submit the unit files.

Create your cluster.
Paste the contents of bare_metal/user-data into your cloud config file. Be sure to alter the networking information to match your setup.
Go to http://discovery.etcd.io/new and copy the URL that it prints in the browser, pasting it into the userdata text area instead of the one that is already there.
Install Paz:

$ ssh-add ~/.ssh/id_rsa
$ FLEETCTL_TUNNEL=<MACHINE_IP> fleetctl -strict-host-key-checking=false start unitfiles/1/*

...where <MACHINE_IP> is an IP address of any node in your cluster.
You can wait for all units to be active/running like so:

$ FLEETCTL_TUNNEL=<MACHINE_IP> watch -n 5 fleetctl -strict-host-key-checking=false list-units

Once they're up you can install the final services:

$ FLEETCTL_TUNNEL=<MACHINE_IP> fleetctl -strict-host-key-checking=false start unitfiles/2/*
