This is the basic usage of Ansible Playbook. Playbook is written as YAML file. |

[1] | For example, create a Playbook that a file exists with the same permission. |

vi playbook_sample.yml # target host or group - hosts: 10.0.0.51 tasks: # any task name - name: Test Task # use file module to set the file state file: path: /home/freebsd/test.conf state: touch owner: freebsd group: freebsd mode: 0600 # run Playbook freebsd@dlp:~ $ ansible-playbook playbook_sample.yml PLAY [10.0.0.51] ******************************************************************* TASK [Gathering Facts] ************************************************************* ok: [10.0.0.51] TASK [Test Task] ******************************************************************* changed: [10.0.0.51] PLAY RECAP ************************************************************************* 10.0.0.51 : ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0 # verify freebsd@dlp:~ $ ansible 10.0.0.50 -m command -a "ls -l /home/freebsd" 10.0.0.51 | CHANGED | rc=0 >> total 1 -rw------- 1 freebsd freebsd 0 Sep 11 10:25 test.conf |
