To use the role in a playbook, a YAML file wazuh-manager.yml can be created with the contents below:

- hosts: wazuh-manager
  roles:
    - ansible-wazuh-manager
    - ansible-filebeat-oss

Custom variable definitions for different environments can be set when configuring the installation. For example: vars-production.yml:

filebeat_output_indexer_hosts: '10.1.1.11:9200'

wazuh_manager_fqdn: "wazuh-manager"

wazuh_manager_config_overlay: true
wazuh_manager_json_output: 'yes'
wazuh_manager_alerts_log: 'yes'
wazuh_manager_logall: 'no'
wazuh_manager_log_format: 'plain'

wazuh_manager_connection:
  - type: 'secure'
    port: '1514'
    protocol: 'tcp'

wazuh_manager_authd:
  enable: true
  port: 1515
  use_source_ip: 'no'
  force:
    - enabled: 'yes'
      disconnected_time:
        enabled: yes
        value: '1h'
      after_registration_time: '1h'
      key_mismatch: 'yes'
  purge: 'no'
  use_password: 'no'
  ssl_agent_ca: null
  ssl_verify_host: 'no'
  ssl_manager_cert: null
  ssl_manager_key: null
  ssl_auto_negotiate: 'no'

Agentless host credentials can be configured in the file: ansible-wazuh-manager/vars/agentless_creds.yml. Set many as you need:

# Be sure you encrypt this file with ansible-vault.
agentless_creds:
 - type: ssh_integrity_check_linux
   frequency: 3600
   host: root@example1.net
   state: periodic
   arguments: '/bin /etc/ /sbin'
   passwd: qwerty
 - type: ssh_integrity_check_bsd
   frequency: 3600
   host: user@example2.net
   state: periodic
   arguments: '/bin /etc/ /sbin'
   passwd: qwerty

Finally, the authd service password can be set in the file ansible-wazuh-manager/vars/authd_pass.yml:

# Be sure you encrypt this file with ansible-vault
authd_pass: foobar

Warning

We recommend the use of Ansible Vault to protect Wazuh API and agentless credentials.

To run the playbook for a specific environment, the command below is run:

$ ansible-playbook wazuh-manager.yml -e@vars-production.yml

The example above will install Wazuh Manager and Filebeat, Filebeat will be configured to forward data to 10.1.1.11:9200 as Indexer node, also it will set various agentless hosts configurations including their credentials, the Wazuh API and the authd will be configured as well.
