| | 20 | = STEPS FOR EXECUTING EXERCISE = |
| | 21 | |
| | 22 | == Experiment with various Ansible modules: ping, shell, setup == |
| | 23 | |
| | 24 | Next, get familiar with some basic Ansible commands . The '''ping''' module simply tries to do a SSH login to a node and reports success or failure. Run the following command on your controller: |
| | 25 | |
| | 26 | {{{ |
| | 27 | $ ansible nodes -i ansible-hosts --private-key id_rsa -u root -m ping |
| | 28 | }}} |
| | 29 | |
| | 30 | If you don’t see success everywhere then there is something wrong with your setup. Ask one of the tutorial leaders for help. |
| | 31 | |
| | 32 | The '''shell''' module lets you run arbitrary SSH commands in parallel across a set of hosts. It’s useful for poking around, or if there is no Ansible module with the functionality you need. Try it out: |
| | 33 | |
| | 34 | {{{ |
| | 35 | $ ansible nodes -i ansible-hosts --private-key id_rsa -u root -m shell -a "hostname" |
| | 36 | }}} |
| | 37 | |
| | 38 | You can replace ''hostname'' above with any other Linux command. |
| | 39 | |
| | 40 | == Create an Ansible playbook to achieve the tutorial objective == |
| | 41 | |
| | 42 | == Run the playbook == |
