Configure Ansible

By default, Ansible’s configuration file location is /etc/ansible/ansible.cfg. In most cases, the default configurations are enough to get you started using Ansible. In this example, you will use Ansible’s default configurations.

• To view a list of all current configs available to your control node, use the ansible-config command line utility.

ansible-config list

Create an Ansible Inventory

Ansible keeps track of its managed nodes using an inventory file located in /etc/ansible/hosts. In the inventory file, you can group your managed nodes and use these groups to target specific hosts that make up your infrastructure

• Add your nodes to the default inventory file.

File: /etc/ansible/hosts
