Example configurations (hosts.yml)

A combination of the configurations described below should be possible. That'd allow you to run/manage a fleet of nodes on different clouds and locations. For more info, refer to ansible's inventory documentation: https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html

The old machine running in my grandma's basement

Assuming that:

• its ip is 1.2.3.4
• it has ssh access
• it has a user named luis in its sudoers group with password nicepassword
• it doesn't have an external drive attached, so we store the blockchain on the main drive

all:
  children:
    hetzner_nodes:
      hosts:
    digitalocean_nodes:
      hosts:
        donode1:
    vultr_nodes:
      hosts:
    preexisting_nodes:
      hosts:
        grandmasbasement1:
          ansible_host: 1.2.3.4
          ansible_user: luis
          ansible_become: true
          ansible_become_password: nicepassword
          device_name: ''
          volume_mountpoint: ''

But if it has an external drive that we can use to store the blockchain, attached on /dev/sda2; we can do the following:
