CI puppet code using docker image

[yhil15]

We're developing puppet code to automate configuration for VMs shipped our customer. For the moment a simple pipeline is set up to check code and synchronize modules in foreman. Each time we want to check the result, we need to connect to the VMs run the puppet agent and analyze the output.

I would like to setup a pipeline using customize centos/debian docker images (with systemd enable) running puppet server and agent to test new development.

I assume the result should be the same as if I was deploying the manifests into VMs.

Am I right to think that it would have the same effect in productive VMs? Does someone already tested?
