    +# Pidgin Bamboo Terraform
    +
    +# Requirements
    +
    +terraform and terraform-libvirt provider
    +
    +# Usage
    +
    +You need to have a `node.tfvars` in the `nodes/` directory which has contents
    +like the following.
    +
    +```
    +libvirt_uri = "qemu:///system"
    +admin_ssh_pubkey = "ssh pubkey"
    +
    +worker_count = 2
    +```
    +
    +`libvirt_uri` is the connect string for libvirt and `admin_ssh_pubkey` is the
    +SSH pubkey that should be accepted for the root user.
    +
    +`worker_count` is the number of Bamboo agents to provision.
    +
    +Once that file is created you provision it via:
    +
    +```
    +make plan NODE=node1
    +make apply NODE=node1
    +```
    +
    +
    +# Terraform Host
    +
    +mkisofs is needed on the machine where terraform is running from to be able to
    +create cloudinit isos.
