## Configuration Management Tools
Configuration management tools such as Puppet, Chef, Ansible, Salt, etc. make
automation and deployment a whole lot easier and more manageable. Step CLI and
CA are built with automation in mind and are easy to configure using your
favorite tools
# Puppet
The following are snippets and files that users can add to their puppet
manifests to easily instrument services with TLS.
** [step.pp](./puppet/step.pp) ** - Install `step` from source and configure the `step` user, group,
and home directory for use by the Step CLI and CA.
** [step_ca.pp](./puppet/step_ca.pp) ** - Install `step-ca` from source. Configure
certificates and secrets and run the Step CA.
** [tls_server.pp](./puppet/tls_server.pp) ** - This is your service, instrumented
with the Step CA SDK to request, receive, and renew TLS certificates. See
[the bootstrap-tls-server](./bootstrap-tls-server/server.go) for a
simple integration example.
**Note:** This is a significantly oversimplified example that will not work standalone.
A complete Puppet configuration should use a service manager (like
[systemctl](https://www.digitalocean.com/community/tutorials/how-to-use-systemctl-to-manage-systemd-services-and-units))
and a secret store (like [Hiera](https://puppet.com/docs/puppet/6.0/hiera_intro.html)).
If you are interested in seeing a more complete example please let us know and we'll
make one available.
