Playbooks

Official Docs

---

Ansible Playbooks provide a repeatable, reusable, simple configuration management and multimachine deployment system that is well suited to deploying complex applications. If you need to execute a task with Ansible more than once, you can write a playbook and put the playbook under source control. You can then use the playbook to push new configurations or confirm the configuration of remote systems.

Playbooks allow you to perform the following actions:

• Declare configurations.

• Orchestrate steps of any manual ordered process on multiple sets of machines in a defined order.

• Launch tasks synchronously or asynchronously.

Creating a playbook

---

Examples below. Create this in the same directory as your inventory file.

install_apache.yml

 --- # be sure to add these 3 hyphens

 - hosts: all # Note the - (hyphen) at beginning of block. 
   become: true # run as sudo
   tasks: # begin list of tasks

   - name: install apache2 package # keep descriptive, what task does
     apt: # module to run
       name: apache2 # what to install 

Run the playbook
