Until now, I think that you can use Puppet for your own projects. But, like codding, you will have mistakes while deploy to servers. I will list some of errors I sometimes get.

1. Puppet Agent Can not connect to Puppet Master

- You didn’t defined the Node using the node keyword.
- Puppet master somehow doesn’t regconize your code.

Fix :
- Maybe you are mistyping at /etc/puppet/manifests/site.pp:7, fix it.
- Maybe you are calling a resource type from uninstalled module, Just check and install this module.
- Maybe Puppet Master doesn’t regconize your new code, restart puppet master service.

Fix :
- Check for the declaration of this resource.
- If it is not neccessary, remove the require parameter.
TIPS
While debugging Puppet Manifest, keep in mind that Puppet throw the exception very clearly about the Location of the error , follow it.
Puppet Master sometimes doesn’t regconize your latest code, restarting Puppet master services may help.
