Example Playbook

This an example of how to install a SLURM cluster:

- hosts: controller
  roles:
  - { role: 'darrylweaver.slurm', slurm_type_of_node: 'controller', slurm_server_ip: '{{ansible_default_ipv4}}', slurm_worker_nodenames: "{{ groups['wns']|map('extract', hostvars, 'ansible_hostname')|list }}" }

- hosts: workers
  roles:
  - { role: 'darrylweaver.slurm', slurm_type_of_node: 'worker', slurm_server_ip: "{{hostvars['server']['ansible_default_ipv4']}}" }
