To use it in a playbook, specify: community.mongodb.mongodb_replicaset.
New in version 1.0.0: of community.mongodb
Synopsis
- Initialises a MongoDB replicaset in a new deployment.
- Validates the replicaset name for existing deployments.
- Advanced replicaset member configuration possible (see examples).
Requirements
The below requirements are needed on the host that executes this module.
- pymongo
Parameters
| Parameter | Choices/Defaults | Comments |
|---|---|---|
| arbiter_at_index integer | Identifies the position of the member in the array that is an arbiter. | |
| auth_mechanism string |
| Authentication type. |
| chaining_allowed boolean |
| When settings.chaining_allowed=true, the replicaset allows secondary members to replicate from other secondary members. When settings.chaining_allowed=false, secondaries can replicate only from the primary. |
| connection_options list / elements=raw | Additional connection options. Supply as a list of dicts or strings containing key value pairs seperated with '='. | |
| election_timeout_millis integer | Default: 10000 | The time limit in milliseconds for detecting when a replicaset's primary is unreachable. |
| heartbeat_timeout_secs integer | Default: 10 | Number of seconds that the replicaset members wait for a successful heartbeat from each other. If a member does not respond in time, other members mark the delinquent member as inaccessible. The setting only applies when using protocol_version=0. When using protocol_version=1 the relevant setting is settings.election_timeout_millis. |
| 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. | |
| members list / elements=raw | Yaml list consisting of the replicaset members. Csv string will also be accepted i.e. mongodb1:27017,mongodb2:27017,mongodb3:27017. A dictionary can also be used to specify advanced replicaset member options. If a port number is not provided then 27017 is assumed. | |
| protocol_version integer |
1 | Version of the replicaset election protocol. |
| replica_set string | Default: "rs0" | Replicaset name. |
| ssl boolean |
| 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 |
| 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 boolean |
| Performs some basic validation on the provided replicaset config. |
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
