To use it in a playbook, specify: community.mongodb.mongodb_status.

New in version 1.0.0: of community.mongodb

Synopsis

  • Validates the status of the replicaset.

  • The module expects all replicaset nodes to be PRIMARY, SECONDARY or ARBITER.

  • Will wait until a timeout for the replicaset state to converge if required.

  • Can also be used to lookup the current PRIMARY member (see examples).

Requirements

The below requirements are needed on the host that executes this module.

  • pymongo

The number of seconds to wait between polling executions.
login_database
string
Default:
"admin"
The database where login credentials are stored.
login_host
string

The MongoDB server port to login to.
login_user
string
The MongoDB user to login with.
Required when login_password is specified.
poll
integer
Default:
1
The maximum number of times to query for the replicaset status before the set converges or we fail.
replica_set
string
Default:
"rs0"
Replicaset name.
ssl
boolean
    Choices:
  • no ←
  • yes
Whether to use an SSL connection when connecting to the database.
ssl_ca_certs
string
The ssl_ca_certs option takes a path to a CA file.
ssl_cert_reqs
string
    Choices:
  • CERT_NONE
  • CERT_OPTIONAL
  • CERT_REQUIRED ←
Specifies whether a certificate is required from the other side of the connection, and whether it will be validated if provided.
ssl_certfile
string
Present a client certificate using the ssl_certfile option.
ssl_crlfile
string
The ssl_crlfile option takes a path to a CRL file.
ssl_keyfile
string
Private key for the client certificate.
ssl_pem_passphrase
string
Passphrase to decrypt encrypted private keys.
validate
string
    Choices:
  • default ←
  • votes
  • minimal
The type of validate to perform on the replicaset.
default, Suitable for most purposes. Validate that there are an odd number of servers and one is PRIMARY and the remainder are in a SECONDARY or ARBITER state.
votes, Check the number of votes is odd and one is a PRIMARY and the remainder are in a SECONDARY or ARBITER state. Authentication is required here to get the replicaset configuration.
minimal, Just checks that one server is in a PRIMARY state with the remainder being SECONDARY or ARBITER.

Notes

Note

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"
