I've been trying to learn K8s and more recently the Gateway API. The struggles are that most Helm charts don't know Gateway (most are barely Ingressroute) and I'm trying to find a solution to one service affecting the other gateways.when a service cannot find a pod, the httproute fails and when one route fails, the ingress fails. It's a weird cascading problem.
Right now, I'm considering adding a secondary service to each gateway that resolves to a static error page. I haven't looked into it yet; it cane to me in the brief moment of clarity before I fell asleep last night.
Also, I may be doing everything wrong, but I am learning and learning is fun.
Check your power source. Swap it as a test. I've spent too much time debugging SD card issues only to discover the power supply was going bad or underperforming.
