As many others have said, not allowing inbound WAN connections into my LAN is an important step. I also run k3s on my server with Calico as the CNI and make heavy use of network policies to keep anything I’m running from misbehaving. That, along with easy ingress makes k3s worth it for me over Docker Compose. I use OpenWRT on my router and force certain devices to run through a VPN and block other devices from the internet entirely.
