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
Task definitions or Playbooks
editTask 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.yml
ansible-playbook my_new_created_playbook.yml -f 10
-f 10 parallelize 10 executions
-f forks
Create "Executable" Playbooks
editAdd 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.
