Neo4j Helm chart for cluster deployments
To offer the flexibility required to cluster users, the Helm chart for clusters takes a modular approach: the typical cluster deployment requires several Helm chart installations. For example, a cluster with three servers requires installing the neo4j chart three times. By separating the charts up, users can create a different topology of Neo4j and a different topology in their Kubernetes clusters to suit their needs.
The following diagram is a schematic representation of the Helm charts involved and the Kubernetes and Cloud resources they instantiate when installed:
The diagram shows an example of a Neo4j cluster setup with three servers. The Kubernetes setup includes a headless service for accessing the cluster from inside Kubernetes and a load-balancer service for accessing the cluster from outside Kubernetes.
