Clustering nodes just for management

[yourkey]

Hello Everyone!

We are planning to use ProxMox for our production environment. We will probably have around 2-4 Servers.
I was reading clustering part of documentation and other threads but didn't find my answer.

My question:
Is it doable to cluster ProxMox servers only and only to manage VMs from a single api endpoint? I don't need any kind of VM HA/replication, storage replication and ...(I would like to test live migration though).
What i want is to create my VMs with IaC/get information of all VMs using single API endpoint, API username and API token.

For more information:
- I want to use telmate/proxmox TF provider and I see a target_node option. So I'm considering that is for targeting a specific in the cluster to create VM on.
- For provisioning created VMs I want to use Ansible and there is an inventory module for ProxMox(community.general.proxmox). So I want to know for example if I give one of my cluster nodes API endpoint address to this module will response of API call has all information from all of my VMs in the cluster?

Also is it doable to test my need with two nodes since right now I have only two nodes for my test environment?

Thanks in advanced!

yes, you can pick any node in a cluster at any time to use as your API end-point that can reach any VM. Assuming, of course, that that node is healthy.

Also is it doable to test my need with two nodes since right now I have only two nodes for my test environment?

yes, of course. You can even install the Proxmox cluster as VMs inside any other hypervisor (proxmox included) and have a separate test bed.

To add to that, you will even be able to transfer VM's/LXC's between the managed (cluster-)nodes.
Just be aware that as you do not have shared storage it will mean when you transfer a box it will shutdown, and then gets sent over the wire, and when sent will be available on the other box.

Prior to having the luxury of having shared storage this was the way i had 4 machines running as a cluster/single point of administration.
