Examples

# Get all current balancer pool members' attributes:
- apache2_mod_proxy:
    balancer_vhost: 10.0.0.2

# Get a specific member's attributes:
- apache2_mod_proxy:
    balancer_vhost: myws.mydomain.org
    balancer_suffix: /lb/
    member_host: node1.myws.mydomain.org

# Enable all balancer pool members:
- apache2_mod_proxy:
    balancer_vhost: '{{ myloadbalancer_host }}'
  register: result
- apache2_mod_proxy:
    balancer_vhost: '{{ myloadbalancer_host }}'
    member_host: '{{ item.host }}'
    state: present
  with_items: '{{ result.members }}'

# Gracefully disable a member from a loadbalancer node:
- apache2_mod_proxy:
    balancer_vhost: '{{ vhost_host }}'
    member_host: '{{ member.host }}'
    state: drained
  delegate_to: myloadbalancernode
- wait_for:
    host: '{{ member.host }}'
    port: '{{ member.port }}'
    state: drained
  delegate_to: myloadbalancernode
- apache2_mod_proxy:
    balancer_vhost: '{{ vhost_host }}'
    member_host: '{{ member.host }}'
    state: absent
  delegate_to: myloadbalancernode
