I have a Proxmox set up and it is accessible only through a special VPN. Inside the Proxmox I have a VM with a gitlab runner. I want to use the gitlab runner to provision new VMs to proxmox using Terraform through the Proxmox API. I thought that if I created the VM inside the proxmox it would have access to it, but it doesn't. What would be the best way to access the API through the runner? Currently the runner VM is inside an internal network managed by an Nginx reverse proxy.
