  • Increasing the usefulness of your Kubernetes Ingress logging

    Increasing the usefulness of your Kubernetes Ingress logging

    Like most cloud folks you are probably using Kibana + Elasticsearch as part of your log management solution. But did you know with a little regex-fu you can make that logging more interesting? See the kibana expansion in the image, the URI, host, service, etc are all expanded for your reporting pleasure. First, lets install…

    A museum is where you go to see old technology, now retired. The steam museum, etc. Let’s get together and create an IPv4 museum. It will have 2^32 exhibits. There will be Class-A halls, class-B halls, class-C halls. I’m not sure yet how to arrange the class-D hall, maybe its everywhere and nowhere at the…
