# names and passwords for administrative users
mongodb_user_admin_name: siteUserAdmin
mongodb_user_admin_password: passw0rd

mongodb_root_admin_name: siteRootAdmin
mongodb_root_admin_password: passw0rd
```

#### Usage

Add `greendayonfire.mongodb` to your roles and set vars in your playbook file.

Example vars for authorization:
```yaml
mongodb_conf_auth: true
mongodb_users:
  - {
    name: testUser,
    password: passw0rd,
    roles: readWrite,
    database: app_development
}
```
Required vars to change on production:
```yaml
mongodb_user_admin_password
mongodb_root_admin_password
```
Example vars for replication:
```yaml
mongodb_login_host: 192.168.56.2      # Mongodb master host

# mongodb_replication_params should be configured on each replica set node
mongodb_replication_params:
  - { host_name: 192.168.56.2, host_port: "{{ mongodb_conf_port }}", host_type: replica }
  # host_type can be replica(default) and arbiter
```
