Pruning elastics with Kubernetes CronJobs

I’m using ElasticSearch and fluent-bit for some logging in a Kubernetes cluster.…
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…
