Group Variables in Ansible Inventory File

From bib. source

The […] block adds variables to the multi group that will be applied to all[sic] servers within multi and all its children.

The block referred to that exemplifies the creation of variables for groups is as follows (Geerling 2023, 22):

# Variables that will be applied to all servers
[multi:vars]
ansible_user=vagrant
ansible_ssh_private_key_file=~/.vagrant.d/insecure_private_key

When it is said that the variables added to the multi group are applied to all servers and group children within multi, they are referring to those servers and group children assigned to it elsewhere in the INI configuration file they reside in, as shown here (hence why INI file syntax is followed).

What’s important to note about this example block for creating group variables is that it does so by appending :vars at the end of the group name assigned to that section of the INI file, in-between the square brackets.
