Here are some coding examples for Docker and Kubernetes that you can use to demonstrate the practical aspects of these technologies

Docker Example: Creating a Simple Docker Container

# Dockerfile
FROM ubuntu:latest
LABEL maintainer="yourname@example.com"

RUN apt-get update && apt-get install -y nginx
EXPOSE 80

CMD ["nginx", "-g", "daemon off;"]

To build and run the Docker container:

docker build -t my-nginx-container .
docker run -p 8080:80 my-nginx-container

Kubernetes Example: Deploying a Web Application

# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-web-app
spec:
  replicas: 3
  selector:
    matchLabels:
      app: my-web-app
  template:
    metadata:
      labels:
        app: my-web-app
    spec:
      containers:
      - name: web-app-container
        image: nginx:latest
        ports:
        - containerPort: 80

To deploy the application:

kubectl apply -f deployment.yaml

Kubernetes Example: Creating a LoadBalancer Service

# service.yaml
apiVersion: v1
kind: Service
metadata:
  name: web-app-service
spec:
  selector:
    app: my-web-app
  ports:
    - protocol: TCP
      port: 80
      targetPort: 80
  type: LoadBalancer

To create the LoadBalancer service:

kubectl apply -f service.yaml

Kubernetes Example: Scaling a Deployment

To scale the number of replicas in a Deployment:

kubectl scale deployment my-web-app --replicas=5

Kubernetes Example: ConfigMap for Environment Variables

# configmap.yaml
apiVersion: v1
kind: ConfigMap
metadata:
  name: app-config
data:
  DATABASE_URL: "mongodb://db.example.com"
  API_KEY: "your-api-key"

To create the ConfigMap and use it in a Pod:

kubectl apply -f configmap.yaml

# In a Pod's spec:
spec:
  containers:
  - name: app-container
    image: my-app-image
    envFrom:
      - configMapRef:
          name: app-config

These examples provide a glimpse into the world of Docker and Kubernetes. They demonstrate creating Docker containers, deploying applications in Kubernetes, creating services, scaling, and utilizing ConfigMaps. Exploring these examples further and experimenting with them will help you gain a deeper understanding of how Docker and Kubernetes work and how they can be utilized in real-world scenarios.
