When I spin up my AWS machine, the first thing I do is run hostnamectl set-hostname myhost.test.com but then when I install and run puppet, it is pulling standard-1-ami.test.com as the cert name. standard-1-ami is the name of my AMI.
Where is it getting this name from on the OS?

This instance hostname setting is happening how; auser_dataargument in Terraform? A Puppet provisioner in Packer? Hostname setting on AWS can be finicky, and Puppet relies on the FQDN by default, but you can also configure it via the Puppet conf: puppet.com/docs/puppet/5.5/…

My first guess would be that Puppet is using thehostnamecommand to determine the hostname. Which result does that give?

I have this issue as well. Every time I make a new machine, without setting the hostname in a userdata script, I have this issue. I have noticed that the initial hostname is cached somewhere in memory.
Here's how I fix it:
Hostname: new_host ; IP: 192.168.10.50 ; DomainName: inside.myhouse.comhostnamectl set-hostname new_hostecho "192.168.10.50 new_host.inside.myhouse.com new_host" >> /etc/hostsecho "new_host" > /etc/hostnameservice network restart
These 3 places are where the hostname "lives" or "can be retrieved.
To validate my configs, I run these 3 commands:$ hostnamenew_host$ hostname -fnew_host.inside.myhouse.comhostname -i192.168.10.50
Note that, if your prompt is set to have your hostname displayed, your prompt may not change until you log back in. If the hostname & hostname -f commands work, you can run puppet and it should use the correct hostname.
BTW: I use Red Hat. YMMV.
