Variables to hosts - nsg/ansible-inventory GitHub Wiki

You can also assign host variables in the inventory, this is the same like myhost.example.com foo=1 in the ini inventory.

root:
  - name: myhost.example.com
    foo: 1

In this example I use the name option, this is needed if you have anything except a simple list of hosts. The following two examples are identical.

root:
  - name: myhost

root:
  - myhost
