Installation

• Install Ansible

• Add location of the directory containing the ansible binary to your PATH

• Set Locale Encoding to UTF-8

  Ansible requires the locale encoding to be UTF-8. You can either use the LANG prefix when running Ansible commands or set the system-wide locale.

  • Option 1: Use LANG Prefix in Commands

    If you prefer not to change the system-wide locale, you can use the LANG prefix when running Ansible commands:

    LANG=en_US.UTF-8 ansible-playbook your_playbook.yml
    

  • Option 2: Set System-Wide Locale

    • Edit the /etc/default/locale file:

      sudo nano /etc/default/locale
      

    • Set the LANG variable to en_US.UTF-8:

      LANG="en_US.UTF-8"
      

    • Reboot your system or log out and log back in to apply the changes.

Setup Remote Hosts

To run the playbook on a remote machine, follow these steps:

• Create a new file named hosts.ini:

  cp example-hosts.ini hosts.ini
  

• Edit the hosts.ini file to run the playbook on a remote machine

  [<deployment_host>]
  <host_name> ansible_host=<TARGET_IP> ansible_user=<SSH_USER> ansible_ssh_common_args='-o ForwardAgent=yes'
  

  • Replace <deployment_host> with the appropriate host group for the deployment
  • Replace <host_name> with the alias of your choice.
  • Replace <TARGET_IP> with the IP address or hostname of the target machine.
  • Replace <SSH_USER> with the SSH username (e.g., dev, ubuntu).

• Verify that you are able to connect to the host using the following command

  ansible all -m ping -i hosts.ini -k
  
  # Expected output:
  
  # <host_name> | SUCCESS => {
  #  "ansible_facts": {
  #      "discovered_interpreter_python": "/usr/bin/python3.10"
  #  },
  #  "changed": false,
  #  "ping": "pong"
  # }
