base_path: Base path for the shared data folder
server_ip: IP address of the Ophidia server
compute_subnet: Subnetwork for Ophidia io-compute nodes
mysql_subnet: Subnetwork for database access for Ophidia io-compute nodes
deploy_type: Type of deployment ('install' or 'configure')
io_nodes_ips: List of IPs for io-compute nodes
node_type: Type of node ('server' or 'io')

Example Playbook

Here's how to create a playbook to install an Ophidia cluster:

---
- hosts: oph-server
  roles:
    - {role: 'indigo-dc.ophidia-cluster', node_type: 'server', deploy_type: 'install'}

- hosts: oph-io
  roles:
    - {role: 'indigo-dc.ophidia-cluster', node_type: 'io', deploy_type: 'install'}

Here's how to create a playbook to configure an Ophidia cluster:

---
- hosts: oph-server
  roles:
    - {role: 'indigo-dc.ophidia-cluster', node_type: 'server', deploy_type: 'configure', io_nodes_ips: "{{ groups['oph-io']|map('extract', hostvars, 'ansible_default_ipv4')|list }}", mysql_subnet: "{{ ansible_default_ipv4.network }}/{{ ansible_default_ipv4.netmask }}", compute_subnet: "{{ ansible_default_ipv4.network }}/24", server_ip: '{{ ansible_default_ipv4.address }}'}

- hosts: oph-io
  roles:
    - {role: 'indigo-dc.ophidia-cluster', node_type: 'io', deploy_type: 'configure', mysql_subnet: "{{ ansible_default_ipv4.network }}/{{ ansible_default_ipv4.netmask }}", server_ip: "{{hostvars['oph-server']['ansible_default_ipv4']['address']}}"}
