ReplicaSet is responsible to maintain the pod count and make sure the desired count of pods running for any deployment. Step4: Create a K8s Deployment to Deploy Tomcat on Kubernetesĭeployment is a Declarative approach to create and manage pods, when you are creating deployments, replica sets ( new gen replication controller) would be created by default and pods would be managed through this replicaset. Kubectl get nodes command would show the list of nodes available in our cluster ➜ kubectl get nodes Let us list the nodes and make sure they are available. In the first step we have created a Kubernetes cluster with gcloud command line with 3 nodes (or) worker nodes. Gke_kubernetestest-270009_asia-south1-a_mwik8scluster Step3: list the nodes of the cluster Switched to context "gke_kubernetestest-270009_asia-south1-a_mwik8scluster" ➜ kubectl config use-context gke_kubernetestest-270009_asia-south1-a_mwik8scluster So make sure you are switching to the right Kubernetes cluster by changing the context to the Google Kubernetes Engine and to the cluster you have created in the previous step. Kubectl is a command-line interface and administration tool for managing your Kubernetes cluster, Wheater you are using minikube, EKS or GKE the kubectl remains your command-line interface for Your Kubernetes Cluster

Step2: Check the Context is set to your newly created cluster. NAME LOCATION MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VERSION NUM_NODES STATUS To inspect the contents of your cluster, go to: entry generated for mwik8scluster. Cluster is being health-checked (master is healthy).done. Please see for more information on node autorepairs.Ĭreating cluster mwik8scluster in asia-south1-a. This will enable the autorepair feature for nodes. ➜ gcloud container clusters create mwik8scluster -num-nodes 3 This is the easiest way to set up Kubernetes. I have used the gcloud cli command to create a Kubernetes cluster with 3 nodes.
TOMCAT 8 DEPLOY WAR INSTALL
In my local machine, I had to install the gcloud CLI and setup my access with google cloud once this is done. Step1: Creating a GKE Cluster with 3 nodes

Expose it as a Service with Load balancing.Validate if new Pods are created after Scaling up.List the pods created by the deployment.Create a K8s Deployment to Deploy Tomcat on Kubernetes.Check the Context is set to your newly created cluster.Steps to Deploy Tomcat in Kubernetes on Google Cloud which can be pulled directly from this DockerHub using the following command docker pull saravak/tomcat8 We are going to use our Tomcat image we have created in the earlier post.
TOMCAT 8 DEPLOY WAR FREE
You can do all these steps and test this with your Free 12 month Google Cloud account itself but make sure you shut down the resources once your setup is completed to avoid charges. We are taking Google Cloud – Kubernetes Engine (GKE) for our example and creating our Kubernetes Cluster with 3 nodes
