I have managed to run the latest elasticsearch in Kubernetes with only ONE pod. I would like to extend this to a full-blown elasticsearch cluster on Kubernetes. I have checked out https://github.com/pires/kubernetes-elasticsearch-cluster but it is not maintained anymore and does not have the latest ES docker image. I tried to use the .yaml files from that github with the latest ES image from docker hub but have not been able to set up the cluster. Any advice and insight is appreciated.
