Managing containers in a production environment can be challenging, especially when dealing with a complex application like the Payment App. Kubernetes is an open-source container orchestration platform that helps manage and automate containerized applications. It provides a scalable and robust solution for container deployment, scaling, and resource management.

With Kubernetes, you can:

Orchestrate Containers: Kubernetes allows you to define and manage a set of containers that make up your application. It ensures that the desired number of containers are running, and it handles scheduling and scaling based on the defined configuration.
Automate Container Operations: Kubernetes automates several container operations such as container health monitoring, automatic restarts, and scaling based on CPU and memory usage.
Manage Container Networking: Kubernetes manages container networking by assigning each container its own IP address and provides a DNS hostname for each service. This allows seamless communication between containers and services.

To manage the Payment App's containers with Kubernetes, follow these steps:

Define Kubernetes Deployment Configuration: Create a Kubernetes deployment configuration file that specifies the desired number of replicas, container image details, ports to expose, and any other necessary configuration.
Apply Deployment Configuration: Use the kubectl apply command to apply the deployment configuration file and create the necessary resources in Kubernetes.

Here's an example of a Kubernetes deployment configuration for the Payment App:

xxxxxxxxxx
console.log('Kubernetes Apply Command:', kubectlApply);
 
// Replace with relevant Kubernetes configuration
const deployment = {
  apiVersion: 'apps/v1',
  kind: 'Deployment',
  metadata: {
    name: 'payment-app',
    labels: {
      app: 'payment-app'
    }
  },
  spec: {
    replicas: 3,
    selector: {
      matchLabels: {
        app: 'payment-app'
      }
    },
    template: {
      metadata: {
        labels: {
          app: 'payment-app'
        }
      },
      spec: {
        containers: [
          {
            name: 'payment-app-container',
            image: 'your-image-name',
            ports: [
