Examples

- name: Check replicaset is healthy, fail if not after first attempt
  community.mongodb.mongodb_status:
    replica_set: rs0
  when: ansible_hostname == "mongodb1"

- name: Wait for the replicaset rs0 to converge, check 5 times, 10 second interval between checks
  community.mongodb.mongodb_status:
    replica_set: rs0
    poll: 5
    interval: 10
  when: ansible_hostname == "mongodb1"

# Get the replicaset status and then lookup the primary's hostname and save to a variable
- name: Ensure replicaset is stable before beginning
  community.mongodb.mongodb_status:
    login_user: "{{ admin_user }}"
    login_password: "{{ admin_user_password }}"
    poll: 3
    interval: 10
  register: rs

- name: Lookup PRIMARY replicaset member
  set_fact:
    primary: "{{ item.key.split('.')[0] }}"
  loop: "{{ lookup('dict', rs.replicaset) }}"
  when: "'PRIMARY' in item.value"
