I am a Puppet beginner and I can't figure out how I could use an environnent variable in /etc/puppetlab/puppet/puppet.conf to set the certname variable. I would like to use the hostname environnent variable for the certname. I could then deploy a new VM and not need to change every times.

Thank you

certname and environment have different meaning and use on puppet. The former is normally translate to your nodes FQDN and the latter for the Puppet Environment which the node will be belong. ie, production, development - production being the default unless you set it explicitly.

A basic content of puppet.conf for a client node would look like this.

[agent]
server = <your_puppet_master>
certname = <agent_FQDN>
environment = production

Yes of course. I'm sorry I meant the hostname variable of the system. [agent] server = myserver.fqdn certname = $hostname environment = production Thank you

the hostname variable is managed by facter on your instances. If you type facter hostname on each of your instances, you'll see the value that puppet would get from using $::hostname within your manifest

Sounds like your bootstrapping the puppet agent directly into your VM template. You're probably better off performing the puppet agent install as part of the firstboot or some self destructing script. In our case, we're looking to shift server deployments over to Razor, which installs the puppet agent as a post installation step during the kickstart process.

At the moment we only have a few Linux servers. I have no idea of what is a "selft destructing script", "shift server", "Razo". I'm using VMware to host and deploy VM.

Is there any ID I should remove before creating the Template ? I would definitely prefer to adding it to the Template.

I don't know that the type of variable interpolation that you're looking to do is available. What I was suggesting was to bake a start up script into your template that installs the puppet agent the 1st time the VM comes to life, & deletes itself after validating the puppet agent has been installed.
