Final answer:
After installing Ansible, nodes to be managed can be added to the Ansible inventory file, which contains a list of all the nodes that Ansible will manage.
Step-by-step explanation:
After installing Ansible, nodes to be managed can be added to the Ansible inventory file. This file is a simple text file that contains a list of all the nodes that Ansible will manage. Each node is defined using its IP address or hostname along with any necessary configuration parameters. For example:
[webservers]
web1 ansible_host=192.168.1.10 ansible_user=admin
In this example, 'web1' is the node to be managed, '192.168.1.10' is its IP address, and 'admin' is the username to use when connecting to the node.
