Running the Elastic Stack on Kubernetes with ECK

Elastic Cloud on Kubernetes (ECK) automates the deployment and orchestration of the Elastic stack on Kubernetes. Come learn how things work under the hood to understand how ECK manages Elasticsearch clusters. We'll talk about Kubernetes concepts, operators, reconciliation loops and nodes orchestration.

Thank you to our presenter, Sebastien Guilloux.

how to access or send request to elasticsearch cluster from other container (POD which is running different application for ex. nodejs).

... I see the crd's and assuming the operator pod are all created inside the elastic-system namespace...
but looking at the quickstart, no where is it implying into which namespace to push it to... would it make sense to do it into a different namespace and leave elastic-system for the operator, back end supporting bits or is engineering happy that we create our clusters inside it also, thinking a separate ns is best, then you can create multiple clusters, if you want to for whatever strange idea... each isolated from each other and from the operator bits ?

I tried deploying ECK quickstart to my k8s cluster but it can't create persistent volume

If I delete master node with ECK deployed elasticsearch, it cant connect to existing cluster but if an update happens to an Elasticsearch CRD it can patch the master node by restarting it. how does it work? what if due to some reason master node goes down would it be able to pickup from there ? because deleting it manually runs into all sorts of issue.

Why elastic eck needs privilege SCC in openshift ?
