Ansible

Playing with Ansible

Ansible uses SSH to connect to various hosts. For that we need to ensure that the public SSH key of the [[Ansible Controller Node]] is present in each server. Update the authorized_keys in all those servers. We can use [[Vagrant]] to achieve that.

Basics

  • Create a dir ansible_quickstart
  • Create inventory.yaml (We can also create .ini file)
ungrouped:
  hosts:
    localhost
  • Check if the file format is correct. It should be if you are using linting. Read more: Ansible Lint Setup.md.
ansible-inventory -i inventory.yaml --list

  • To verify if the hosts are reachable, we ideally go for a simple ping.

    • For localhost: ansible localhost -m ping

      • Expected outcome:

        ❯ ansible localhost -m ping
localhost | SUCCESS => {
    "changed": false,
    "ping": "pong"
}

    • For servers: ansible <group_name or all> -m ping -i inventory.yaml
