Deploying an Apache Ignite Cluster on Google Kubernetes Engine

Google Kubernetes Engine is a platform that lets us deploy, manage, and scale containerized applications effortlessly. Today, we are going to take a look at how to deploy an Apache Ignite cluster on GKE.

Before we begin, we have to make sure we have the following prerequisites in place:

• We need an active GCP account to utilize the Google Kubernetes Engine.
• Next, install the Google Cloud SDK to interact with GCP services and manage our Kubernetes cluster.
• Then, make sure that we have kubectl installed so that we can interact with our Kubernetes cluster.

Deployment Steps

1. First, we have to run this command to create a GKE cluster:

   gcloud container clusters create ignite-cluster --num-nodes=3 –zone=your-preferred-zone
2. Then, create a ConfigMap with our Apache Ignite configuration. We have to save the Ignite configuration in a file named `ignite-config.xml`. Here’s a sample configuration:

   

   Now, we can create the ConfigMap as seen here:

   kubectl create configmap ignite-config –from-file=ignite-config.xml
3. Next, create a file named `ignite-statefulset.yaml` with the following content.

   

   Then, deploy the StatefulSet:

   kubectl apply -f ignite-statefulset.yaml
4. At this point, we can choose to expose the Ignite cluster outside the Kubernetes cluster by creating a service:

   kubectl expose statefulset ignite-cluster --type=LoadBalancer –name=ignite-service
5. Finally, we can check the status of our deployment as seen here:

   kubectl get pods
kubectl get services

   We will be able to see our Ignite pods running, and if we have exposed the service, it will have an external IP.
