You can confirm this as follows. Grab a laptop and:

• Confirm that on the university internet, 8.8.8.8 resolves the wrong domain.
• Set up a hotspot from your mobile phone, connect the laptop there, then try again.

If the behaviour is different depending on your network, your uni must be redirecting DNS.

I use the built-in Traefik that ships with k3s. Works great for me – a bit of a learning curve, as I was really only familiar with Nginx, but now that I’m more used to it I’m a big fan.

Why not do both? I run proxmox on my physical hardware, then have guest VMs within proxmox that run k8s.

Advantages of proxmox:

• Proxmox makes it easy to spin up VMs for non self host purposes (say I want to play with NixOS)
• Proxmox snapshots make migrations and configuration changes a bit safer (I recently messed up a postgres 15 migration and was able to roll back in a button press)

You can then just run docker images through Proxmox, but I like k8s (specifically k3s) because:

Advantages of k8s:

• Certmanager means your HTTP services automatically get assigned TLS certs essentially for free (once you’ve set up cert manager for the first time, anyway)
• I find k8s’ YML-based configuration easier to track and manage. I can spin my containers up fresh just from my config, without worrying about stray environment settings I might not have backed up.
• k8s makes it easy for me to reason about which services are exposed internally to each other, and which are exposed on the host outside of my k8s cluster.
• k8s services get persistent DNS and IPs within the cluster, so configuring nodes to talk to each other is very easy.

And yeah, this way I get to learn two technologies rather than one 😁

Voice / video requires a separate TURN server, IIRC.
