Prepare the managed nodes

Managed nodes, or hosts, are the devices managed by Ansible Automation Platform. To ensure a secure containerized setup, create a dedicated user on each node for Ansible Automation Platform to use when connecting and running tasks.

Procedure

  1. Log in to the host as the root user.
  2. Create a new user. Replace <username> with the username you want, for example aap. 
    $ sudo adduser <username>
  3. Set a password for the new user. Replace <username> with the username you created. 
    $ sudo passwd <username>
  4. Configure the user to run sudo commands.

    For a secure and maintainable installation, configure sudo privileges for the installation user in a dedicated file within the /etc/sudoers.d/ directory.

    1. Create a dedicated sudoers file for the user: 
      $ sudo visudo -f /etc/sudoers.d/<username>
    2. Add the following line to the file, replacing <username> with the username you created: 
      <username> ALL=(ALL) NOPASSWD: ALL
    3. Save and exit the file.
