A playbook in Ansible is a YAML file that defines a series of tasks to be executed on managed hosts. It allows you to automate configuration management, application deployment, and orchestration. Each playbook consists of one or more "plays," which map a group of hosts to roles and tasks.
Key components of a playbook include:
- Hosts: Specifies the target machines where the tasks will run.
- Tasks: A list of actions to be performed, such as installing packages, copying files, or executing commands.
- Variables: Allow for dynamic content and customization of tasks.
- Handlers: Special tasks that run when notified by other tasks.
Playbooks are essential for defining the desired state of your infrastructure and automating repetitive tasks.
