- **handbook.yml**: is the main playbook, used for most of the situations. The playbook respond to vars configured to hosts. You can, for example, create multiple inventories, each with different host_vars and call this playbook to setup just only triggered roles. Each role has correspondent tags.
- **os-update.yml**: this playbook is useful when you need to update multiple hosts from another host (like a "controller")
- **setup-node.yml**: this playbook helps you to setup a target to allow it to play ansible playbooks
- **ssh-copy-id.yml**: this helps you to send your ssh pubkey to multiple targets for the given user
## Docker
The examples for `Dockerfile.example` and `docker-compose.yml.example` are useful if you need a basic container to test your playbook with different systems (like Centos/ Ubuntu). Copy them and modify as needed :)
