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
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
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
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.
