In the previous tutorial, you learnt How to Setup a Local Kubernetes Cluster (Minikube) and deploy a SpringBoot application<\/a>. You also learn how to access the Minikube dashboard<\/a> in the browser.<\/p>\n

In this lesson, you will learn how to deploy Spring Boot application using a deployment file.<\/p>\n

    \n
  1. Create a Docker Image<\/a><\/li>\n
  2. Create a Deployment File<\/a><\/li>\n
  3. Create a Deployment Object using Apply Command<\/a><\/li>\n
  4. Create and Test the Service<\/a><\/li>\n<\/ol>\n

     <\/p>\n

    1. Create a Docker Image<\/strong><\/h4>\n

    You first need to have a SpringBoot application. Then you also need to create a docker image of your SpringBoot application.<\/p>\n

    Step 1<\/strong> – First use this command to allow Minikube access to our docker repositories:<\/p>\n

    eval $(minikube docker-env)\r\n<\/pre>\n
     <\/p>\n
    Step 2<\/strong> – Use this command to create a docker image.<\/p>\n
    docker build -t springboot-kubernetes:1.0 .\r\n<\/pre>\n
    At this point we have a docker image with name springboot-kubernetes<\/em><\/strong> with a tag of 1.0<\/strong><\/em><\/p>\n
     <\/p>\n
    2. Create a Deployment File<\/strong><\/h4>\n
    Inside the resources directory, create a file named deployment.yaml. The content is as follows:<\/p>\n
    apiVersion: apps\/v1\r\nkind: Deployment\r\nmetadata:\r\n  name: springboot-kubernetes\r\nspec:\r\n  selector:\r\n    matchLabels:\r\n      app: springboot-kubernetes\r\n  replicas: 3\r\n  template:\r\n    metadata:\r\n      labels:\r\n        app: springboot-kubernetes\r\n    spec:\r\n      containers:\r\n        - name: springboot-kubernetes\r\n          image: springboot-kubernetes:1.0\r\n          imagePullPolicy: IfNotPresent\r\n          ports:\r\n            - containerPort: 8080\r\n<\/pre>\n
     <\/p>\n
    3. Create the Deployment Using the Apply Command<\/strong><\/h4>\n
    Now that we have created the deployment file, we need to apply it.<\/p>\n
    Step 1<\/strong> – Start minikube using the command minikube start.<\/p>\n
    Step 2<\/strong>\u00a0– Navigate to the resources directory containing the deployment<\/p>\n
    Step 3<\/strong>\u00a0– Run the command\u00a0 below to apply the deployment<\/p>\n
    kubectl apply -f deployment.yaml\r\n<\/pre>\n
     <\/p>\n
    Step 4<\/strong> – You can check the status of the deployment using the command:<\/p>\n
    kubectl get deployment\r\n<\/pre>\n
     <\/p>\n
    Step 5<\/strong> – Use the command below to view the pods and their statuses:<\/p>\n
    kubectl kubectl get pods\r\n<\/pre>\n
     <\/p>\n
    Step 6<\/strong> – Check the status of the pods using the command<\/p>\n
     kubectl logs \r\n<\/pre>\n
     <\/p>\n
    4. Create and Test the Service<\/strong><\/h4>\n
    We would need to be able to access the application from outside the Kubernetes cluster. For this, we need to create a service object.<\/p>\n
    Step 1<\/strong> – Create a service.yaml file inside the resources directory. This is the content of the service.yaml file<\/p>\n
    apiVersion: v1\r\nkind: Service\r\nmetadata:\r\n  name: springboot-kubernetes-service\r\nspec:\r\n  ports:\r\n    - protocol: \"TCP\"\r\n      port: 8080        # The port inside the cluster\r\n      targetPort: 8080  # The port exposed by the service\r\n  type: NodePort        # Type of service\r\n  selector:\r\n    app: springboot-kubernetes\r\n<\/pre>\n
     <\/p>\n
    Step 2<\/strong> – Apply the service using the command below<\/p>\n
    kubectl apply -f service.yaml\r\n<\/pre>\n
    The service would then be created<\/p>\n
    You can then use kubectl get services<\/strong><\/em> command to check that the services is created.<\/p>\n
    To access the application, you can can use a combination of the internal-ip and the node port. The internal ip and the minikube ip are the same. To get these details, use the command below:<\/p>\n
    kubectl get nodes -o wide\r\n<\/pre>\n
     <\/p>\n
