question about best practice for vm's config of ip/gw/nameservers

[smcracraft]

Hi,

I have a question about best practice in the Proxmox world.

We have Ansible here creating and deleting VM's.

But from there, we want to assign ip, assign gateway, assign name server, etc. to the newly created VM and then we will Ansible everything inside that too.

So somewhat like the "userdata" feature of AWS which will permit post-VM provisioning activity such as ip/gateway/name server/etc and then the entirety of the vm internally to it as well.

I ran across this repo but am not sure what people use here as best practice for the ip+gateway+nameserver-related pieces as standard Proxmox practice.

Thoughts?

https://github.com/rits1902/Proxmox-cloud-init

If there is a standard Proxmox best practice document detailing the subject, that would be more handy and if there is pre-existing GitHub activity which can be used, that would be ideal.

Thanks.

Isn't cloudinit exactly what you're looking for?

Before the cloudinit age, PXE was a big player and still is. We can also install VMs including configuration only via PXE+DNS+DHCP.

Yes, that's what I have in the playbook which is based on https://gitlab.com/morph027/pve-infra-poc

But it fails.

Here's the full error.

Anyone know how I can get at at 500 internal server error exception and the meaning of "data"?

TASK [create vms] ***************************************************************************************************

I've never used it, but maybe @morph027 can jump in as it is his code :-D
