Multiple puppet agents with the same name

[Markus Bischof]

Hi there,

I'm pretty new to puppet and have a general question.

I will have multiple (vagrant) machines wich i want to manage via puppet. The "problem" is that all the machines will have the same name because they are development machines wich are run by different developers. Is it a problem for puppet if all the machines have the same name?

Hi, 

that depends on your manifest and if they need to talk to a puppet master or you are just doing a puppet apply (masterless). 

Have a look at the Vagrantfile docs on puppet provisioners and you may get inspired. Also you can pass in 'puppet_node' names and facts at run time (with a puppet master).

https://docs.vagrantup.com/v2/provisioning/puppet_apply.html

https://docs.vagrantup.com/v2/provisioning/puppet_agent.html

There are other ways to change the hostnames of the machines in Vagrant too:

This.

But please note - the hostname is not the issue here. It's the
duplicated $certname that will cause you head aches.

Do not share a certificate among multiple agents!

If you do want a master and PuppetDB, but have to duplicate host names,
consider using randomized certnames.
