ca_manager/ansible.yaml

---
# This is an example of how to use Ansible with the ca-server shell.
# In this playbook we assume that you are requesting a ssh-host certificate
# to be used by the host `machine.example.com` and that the server hosting
# the ca-server shell is in your inventory under the name `ca_server`.
#
# We are using ed25519 as our preferred algorithm but any other one may be
# just right, be sure to change both the key and certificate destination.
