# Convenience playbooks

• playbooks/clean_all.yml powers off and deletes all VMs in your inventory.
• playbooks/distribute_keys.yml distributes public keys between all nodes, to allow each node to password-less log in to every other node. As this is not essential and can be regarded as a security risk (a worker node probably should not be able to log in to a UCP node, for instance), this playbook is not included in site.yml by default.
