debug boolean |
| show additional debug info. |
eval string | A MongoDB command to run. | |
file string | Path to a file containing MongoDB commands. | |
idempotent boolean |
| Provides a form of pseudo-idempotency to the module. We perform a hash calculation on the contents of the eval key or the file name provided in the file key. When the command is first execute a filed called <hash>.success will be created. The module will not rerun the command if this file exists and idempotent is set to true. |
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. | |
mongo_cmd string | Default: "mongo" | The MongoDB shell command. |
nodb boolean |
| Specify a non-default encoding for output. |
norc boolean |
| Prevents the shell from sourcing and evaluating ~/.mongorc.js on start up. |
quiet boolean |
| Silences output from the shell during the connection process.. |
split_char string | Default: " " | Used by the split action in the transform stage. |
stringify boolean |
| Wraps the command in eval in JSON.stringify(<js cmd>) (mongo) or EJSON.stringify(<js cmd>) (mongosh). Useful for escaping documents that are returned in Extended JSON format. Automatically set to false when using mongo. Automatically set to true when using mongosh. Set explicitly to override automatic selection. |
transform string |
| Transform the output returned to the user. auto - Attempt to automatically decide the best tranformation. split - Split output on a character. json - parse as json. raw - Return the raw output. |
