Inventory of managed nodes
https://www.digitalocean.com/community/tutorials/how-to-manage-multistage-environments-with-ansible
Inventory is defined in /etc/ansible/hosts file. It allows you to define your managed hosts by hostname or IP address, and group them, such as "my_webservers_group" in our example in INI format.
Groups of groups, hierarchies, is also supported using (:children) keyword: [YOUR_NEW_GROUP_OF_GROUPS:children] [1]
#This is a example of a host configuration file. You can use # to include your comments on hosts file foo_server.example.com 192.168.6.1 bar_server.example.com [my_webservers_group] foo5.example.com bar6.example.com [my_dbservers_group] onedb1.example.com twodb.example.com #Example of a server alias on standard Ansible port my_local_defined_hostname ansible_host=192.0.2.50 #Example of a server alias on a non standard Ansible port my_jumper_server_alias ansible_host=192.0.2.50 ansible_port=5555
