ECK on NVMe - how to set up PV and PVC

[dbernard (David Bernard)]

I am a novice with K8S but experiences with Elasticsearch.

I want to run about 8 Elasticsearch pods per server and have each pod claim a NMVe volume.

There will be about 6 servers.

What is the best way to do this?

Do I specifically need to set up zoning to ensure replicas are distributed across servers?

ECK sets up a default affinity rule so the Kubernetes scheduler avoids scheduling 2 Pods of the same Elasticsearch cluster: Advanced Elasticsearch node scheduling | Elastic Cloud on Kubernetes [1.4] | Elastic.

You can tweak these rules yourself, and I also suggest setting up availability zone awareness: Advanced Elasticsearch node scheduling | Elastic Cloud on Kubernetes [1.4] | Elastic.
