Deploying on Kubernetes
Discover ways to deploy Hazelcast clusters in Kubernetes environments.
Hazelcast CP Subsystem can be used safely in Kubernetes only if CP Subsystem Persistence is enabled (Enterprise Feature). Otherwise, a CP Subsystem Group may not recover after scaling the cluster or a rolling upgrade.
If you just want to play with Hazelcast on Kubernetes, execute the following commands to create a Hazelcast cluster
with 3 members in the
default namespace using the
default Service Account.
kubectl apply -f https://raw.githubusercontent.com/hazelcast/hazelcast/master/kubernetes-rbac.yaml kubectl run hazelcast-1 --image=hazelcast/hazelcast:5.2.1 kubectl run hazelcast-2 --image=hazelcast/hazelcast:5.2.1 kubectl run hazelcast-3 --image=hazelcast/hazelcast:5.2.1
Hazelcast members automatically discover themselves and form one Hazelcast cluster.
|For production-grade Kubernetes deployment, use Helm chart or Hazelcast Platform Operator.|
Kubernetes Operators are software extensions to Kubernetes which help you create and manage your applications. Hazelcast Platform Operator automates common management tasks such as configuring, creating, and scaling Hazelcast clusters on Kubernetes and Red Hat OpenShift. By taking care of manual deployment and life-cycle management, Hazelcast Platform Operator makes it simpler to work with Hazelcast clusters.
See the Hazelcast Platform Operator Documentation for more information and find details about deploying a Hazelcast cluster in Kubernetes and also connecting clients outside Kubernetes.
