By creating a YAML file wazuh-manager.yml you can be set the usage of this role:

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

Setting the variables on a separate YAML file is recommended when configuring the installation. For this example we used: vars-production.yml:

filebeat_output_logstash_hosts: '10.1.1.11:5000'

wazuh_manager_fqdn: "wazuh-server"

wazuh_manager_config:
  json_output: 'yes'
  alerts_log: 'yes'
  logall: 'no'
  log_format: 'plain'
  connection:
    - type: 'secure'
      port: '1514'
      protocol: 'tcp'
  authd:
    enable: true
    port: 1515
    use_source_ip: 'no'
    force_insert: 'no'
    force_time: 0
    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'

You can configure Wazuh API user credentials, this could be done by setting the file: ansible-wazuh-manager/vars/wazuh_api_creds.yml located on your Ansible control server, the credentials are in htpasswd format:

# Be sure you encrypt this file with ansible-vault
wazuh_api_user:
- foo:$apr1$/axqZYWQ$Xo/nz/IG3PdwV82EnfYKh/
- bar:$apr1$hXE97ag.$8m0koHByattiGKUKPUgcZ1

Also, you can configure agentless host credentials via the file: ansible-wazuh-manager/vars/agentless_creeds.yml, set many as you need:

# Be sure you encrypt this file with ansible-vault.
agentless_creeds:
 - 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

And the authd service password could be set in the file ansible-wazuh-manager/vars/authd_pass.yml:

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

Next, run the playbook:

$ 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 10.1.1.11:5000 as Logstash node, also it will set various agentless hosts configurations including their credentials, the Wazuh API and the authd will be configured as well.
