Consul
This Ansible role performs a basic Consul installation, including filesystem structure, example configuration, and Consul UI installation.
It does not yet handle full configuration and initialization of a functioning Consul cluster, but that is on the road map for a future version.
Requirements
This role requires a Debian or RHEL family of Linux host; the role is tested with the following specific software versions:
- Ansible: 1.9.2
- Consul: 0.5.2
- Debian: 8

Example Playbook
After you have reviewed and altered any necessary variables, and created a
hosts inventory, basic Consul installation is possible using the
included site.yml playbook:
ansible-playbook -i hosts site.yml
You can also simply pass variables in using the --extra-vars option
to the ansible-playbook command:
ansible-playbook -i hosts site.yml --extra-vars "consul_datacenter=maui"
