Deploy the application

Now, we are ready to push our application. Here we are calling the aws-eks/python3 executor which will define the environment in which the steps of our job will be run. 
  deploy_app:
    executor: aws-eks/python3
    parameters:
      cluster-name:
        type: string
      docker-image-name:
        type: string
      version-info:
        type: string
      aws-region:
        type: string
        default: ""
    steps:
      - checkout
      - run:
          name: Create deployment manifest
          command: |
            BUILD_DATE=$(date '+%Y%m%d%H%M%S')
            cat deployment/goof-deployment-template.yaml |\
               sed "s|DOCKER_IMAGE_NAME|<< parameters.docker-image-name >>|g"\
                 > deployment/goof-deployment.yaml
      - aws-eks/update-kubeconfig-with-authenticator:
          cluster-name: << parameters.cluster-name >>
          install-kubectl: true
          aws-region: << parameters.aws-region >>
      - kubernetes/create-or-update-resource:
          resource-file-path: "deployment/goof-deployment.yaml"
          get-rollout-status: true
          resource-name: deployment/goof
      - kubernetes/create-or-update-resource:
          resource-file-path: "deployment/goof-service.yaml"
In this job, we are passing a few parameters such as the Kubernetes cluster-name and the docker-image-name which references the image we recently created. We are using these values to authenticate to our Kubernetes cluster and also to replace the value of our image in our Kubernetes manifest with the Amazon ECR repository URL and tag. Then,  will invoke the kubernetes/create-or-update-resources command to apply our Kubernetes manifests for the deployment and service.
