How can I deploy an Express app on Kubernetes?

To deploy an Express app on Kubernetes, you'll need to create a Docker image of your app, then define a Kubernetes deployment and service.

What should my Dockerfile look like?

Your Dockerfile should start with a base image like node:14, copy your app files, install dependencies, and specify the command to run your app.

Can you provide an example of a Kubernetes deployment YAML?

Sure! Here's a simple example:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: express-app
spec:
  replicas: 2
  selector:
    matchLabels:
      app: express
  template:
    metadata:
      labels:
        app: express
    spec:
      containers:
      - name: express-container
        image: your-docker-image
        ports:
        - containerPort: 3000
