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

Parameters

Parameter

Comments

The number of seconds to wait between polling executions.

Default: 30

login_database

string

The database where login credentials are stored.

Default: “admin”

login_host

string

The host running MongoDB instance to login to.

Default: “localhost”

login_password

string

The password used to authenticate with.

integer

The MongoDB server port to login to.

Default: 27017

login_user

string

The MongoDB user to login with.

Required when login_password is specified.

poll

integer

The maximum number of times to query for the replicaset status before the set converges or we fail.

Default: 1

replica_set

string

Replicaset name.

Default: “rs0”

ssl

aliases: tls

boolean

Whether to use an SSL connection when connecting to the database.

Choices:

  • no ← (default)

  • yes

ssl_ca_certs

aliases: tlsCAFile

string

The ssl_ca_certs option takes a path to a CA file.

ssl_cert_reqs

aliases: tlsAllowInvalidCertificates

string

Specifies whether a certificate is required from the other side of the connection, and whether it will be validated if provided.

Choices:

  • CERT_NONE

  • CERT_OPTIONAL

  • CERT_REQUIRED ← (default)

ssl_certfile

aliases: tlsCertificateKeyFile

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

aliases: tlsCertificateKeyFilePassword

string

strict_compatibility

boolean

Enforce strict requirements for pymongo and MongoDB software versions

Choices:

  • no

  • yes ← (default)

validate

string

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.

Choices:

  • default ← (default)

  • votes

  • minimal

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"
