k8s-elasticsearch

The purpose of this repository is to deploy Elasticsearch cluster easily in Kubernetes.

Elasticsearch v7+ use cluster.initial_master_nodes instead of discovery.zen.minimum_master_nodes, it's easily to config if elasticsearch run on the bare-metal, but it is troublesome for kubernetes. Because the pod name can not be determined before elasticsearch run. Official or other chart deploy elasticsearch cluster with StatefulSet, it can determine pod name before elasticsearch pod created. But if not use StatefulSet, it's not works well.

This repository solve above problem. Support StatefulSet,Deployment,DaemonSet to deploy elasticsearch cluster.

Usage

Kubernetes

kubectl apply -f elasticsearch-deployment.yaml

Elasticsearch default running in kube-system namespace, modify the elasticsearch-deployment.yaml namespace if you don't want to deploy elasticsearch to kube-system namespace.

Official Native

If not need to this feature, setting container args to eswrapper, it keep the behavior consistent with the official.
