Ansible playbooks[1] are written in YAML text files and define actions to execute against host/devices, check official Ansible playbook introduction: https://docs.ansible.com/ansible/devel/user_guide/playbooks_intro.html
Contents
Task definitions or Playbooks[edit]
Task definitions are defined in text files, called playbooks in Ansible terminology, in YAML format. Execution of task definitions or playbooks are make using ansible-playbook command followed by your desired playbook to execute. Playbooks can also use Jinja templates to enable dynamic expressions and access to variables[2].
Ansible Playbook execution:
ansible-playbook my_new_created_playbook.ymlansible-playbook my_new_created_playbook.yml -f 10-f 10 parallelize 10 executions
-f forks
Create "Executable" Playbooks[edit]
Add the following line #!/usr/bin/env ansible-playbook at the beginning of your playbooks and make it executable chmod +x /path/to/your/playbook.yml to execute without calling ansible-playbook binary.
Ansible Playbooks Examples[edit]
Create a new file touch /tmp/test_file.txt, REMOTE_SERVER should be already present in your Ansible inventory:/etc/ansible/host
Playbook using module file[3]:
#!/usr/bin/env ansible-playbook - hosts: REMOTE_SERVER_HOSTNAME tasks: - name: Ansible create a new file called test_fle.txt in /tmp directory file: path: "/tmp/test_file.txt" state: touch
Important Note: dash symbol (-) and indentation has to be properly formatted.
Additional examples:
Errors[edit]
A playbook must be a list of plays
