community.mongodb.mongodb_status – Validates the status of the replicaset.

Note

This plugin is part of the community.mongodb collection (version 1.3.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install community.mongodb.

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	Choices/Defaults	Comments
auth_mechanism string	Choices: SCRAM-SHA-256 SCRAM-SHA-1 MONGODB-X509 GSSAPI PLAIN	Authentication type.
connection_options list / elements=raw		Additional connection options. Supply as a list of dicts or strings containing key value pairs seperated with '='.
interval integer	Default: 30	The number of seconds to wait between polling executions.
login_database string	Default: "admin"	The database where login credentials are stored.
login_host string	Default: "localhost"	The host running MongoDB instance to login to.
login_password string		The password used to authenticate with. Required when login_user is specified.
login_port integer	Default: 27017	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

Requires the pymongo Python package on the remote host, version 2.4.2+. This can be installed using pip or the OS package manager. @see http://api.mongodb.org/python/current/installation.html

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"

Return Values

Common return values are documented here, the following are the fields unique to this module:

Key	Returned	Description
failed boolean	always	If the module has failed or not.
iterations integer	always	Number of times the module has queried the replicaset status.
msg string	always	Status message.
replicaset dictionary	always	The last queried status of all the members of the replicaset if obtainable.
