Want to try Hazelcast 5.0?

We’ve combined the in-memory storage of IMDG with the stream processing power of Jet to bring you an all new Hazelcast platform.

Kubernetes/OpenShift Deployment

Hazelcast provides a few methods to simplify deploying Hazelcast cluster into Kubernetes-based environments. For production-grade Kubernetes deployment, use Helm chart or Kubernetes/OpenShift Operator.

Quick Start

If you just want to play with Hazelcast on Kubernetes, execute the following commands to create Hazelcast cluster with 3 members into default namespace using the default Service Account.

kubectl apply -f https://raw.githubusercontent.com/hazelcast/hazelcast-kubernetes/master/rbac.yaml
kubectl run hazelcast-1 --image=hazelcast/hazelcast:$HAZELCAST_VERSION
kubectl run hazelcast-2 --image=hazelcast/hazelcast:$HAZELCAST_VERSION
kubectl run hazelcast-3 --image=hazelcast/hazelcast:$HAZELCAST_VERSION

Hazelcast members automatically discovers themselves using the Hazelcast Kubernetes Discovery plugin and therefore form one Hazelcast cluster.

Helm Chart

Helm is a package manager for Kubernetes. Hazelcast is distributed in a form of Helm Charts:

See the Hazelcast Helm Charts documentation for more details.

Kubernetes/OpenShift Operator

Kubernetes Operators are software extensions to Kubernetes which help you create and manage your applications. You can deploy and manage Hazelcast using the following Operators:

There are a few different ways in using Hazelcast Operators:
