Ansible Intro

Step 1 of 5

Step 1 - Execution

You can run Ansible in two different modes:

ad-hoc: perform one-off command on a single host or a group of hosts

structured: execute ansible playbook (script) that performs a number of predefined tasks on remote servers in a specific order

Try running ansible (ad-hoc mode) and you will notice that it expects host-pattern (names of servers to which you want to talk to) and additional options like the command that you want to execute:

Usage: ansible host-pattern [options]

Then run ansible-playbook (structured mode) which needs only the name of playbook as everything else can be defnied within the playbook:

Usage: ansible-playbook playbook.yml

We will start with the ad-hoc mode.
