Hi
here is a k8s-logging-helm chart for collecting logs streams in kubernetes clusters. It can help to experiment with an elasticsearch scalable setup based on OpenDistro for Elasticsearch. It is versatile and scalable and can be provisioned from a Minikube single node instance up to mighty cluster sizes.
Although the main purpose is to serve experimentation and learning activities it has the needed ingredients to facilitate production setups.
Cheers
Niki
