Getting Started with Hazelcast on Azure Kubernetes Service Sharath Sahadevan May 18, 2020 Share Subscribe This blog shows you how you can install Hazelcast on Azure Kubernetes Service (AKS) and connect to the cluster using an Hazelcast client. It assumes some familiarity with Kubernetes , Azure and Azure Cloud shell. The goal of this blog is to keep things simple and show you the steps to get up and running in a few minutes. Here are the steps to get Hazelcast up and running on AKS. Set up AKS on your Azure account Use the Azure portal or CLI to create an AKS instance. Note the resource group and the name of the cluster that you created. You will use those to get the AKS credentials below. Get credentials from your AKS instance Launch the Azure cloud shell. The Azure cloud shell comes preinstalled with the az command line interface. Run the following command in your Azure cloud shell providing the resource group and clustername that you noted above: az aks get-credentials --resource-group HazelcastDemo --name democluster You can now verify that you can run kubectl commands. kubectl get all Install Hazelcast I used the helm charts to install Hazelcast on the Kubernetes cluster. Note: If you are using the Azure cloud shell , helm is already pre-installed. You can find additional details here. helm repo add hazelcast https://hazelcast.github.io/charts/ helm install my-release --set service.type=LoadBalancer,service.clusterIP="",cluster.memberCount=1 hazelcast/hazelcast Only one Hazelcast member is instantiated to keep things simple. As you scale the number of Hazelcast instances discovery of members in the cluster and Role Based Access Control ( RBAC ) configurations will come into play. You can find additional details here. The screenshot below shows Hazelcast installed on the pods. If the install is successful, you should see an external-IP assigned to both the hazelcast and hazelcast-mancenter services. Validate by Launching an External Client and Management Center You can now view the management center at the exposed external IP address. Similarly, you can connect a Hazelcast Client to Hazelcast external IP address. Eclipse screen showing the Java client. Running the client and connecting to the Hazelcast cluster on Azure. Conclusion In summary, it is pretty easy to get started on Hazelcast in any environment that has Kubernetes installed.
