I need to take a step back and reassess my network setup. Here’s what I have:
• Proxmox VE running on a mini PC, directly connected to my router (no VLANs).
• The Proxmox host has a single virtual adapter with a static private IP, which is also reserved on the router.
• A Cloudflared LXC (running in Proxmox) with its own reserved private IP on the same subnet as the Proxmox host.
• A VM on the same subnet running Docker, where the containers are on a user-defined bridge network, but this bridge network is on a different subnet than the host.
My goal:
I want the Cloudflared LXC to properly route public hostname(s) to the appropriate Docker containers (which provide public services) on the VM.
The challenge:
Since the Docker containers are on a different subnet than the VM itself, how should I structure my networking so that:
1. Cloudflared can route requests correctly to the Docker services.
2. The setup remains clean and maintainable.
What’s the best approach to configure this? Should I adjust Proxmox networking, use additional routes, or take a different approach?
@suzannealdrich I would run `cloudflared` as a container next to the service(s) it's exposing. There's no harm in running multiple instances, even on the same host.
@willglynn ok so I think what you’re saying is have another tunnel in the docker. The outside tunnel is still useful for setting up my private network tunneling for the proxmox host itself.
@suzannealdrich Yep! The Dockerized `cloudflared` can address containers by name or by alias, while the LXC `cloudflared` can keep doing whatever it's doing.
