I had thought of that, I didn’t really like the idea of using a third party service to access my machines.

Also I didn’t mention in the post, but, while my ISP gives me a public IP, I only use port forwarding to wireguard into my home networks. My services are exposed via a vps hosted on oracle cloud free tier free, which forwards public traffic to my server via another wireguard connection

How is that different from a VM and using docker inside it? Any specific advantages/disadvantages to both approaches?
