Pods, services and deployments

Our Deployment

cat <<EOF | kubectl apply -f -
apiVersion: apps/v1 
kind: Deployment
metadata:
  name: webapp-deployment
spec:
  selector:
    matchLabels:
      app: webapp
  replicas: 3
  template:
    metadata:
      labels:
        app: webapp
    spec:
      containers:
      - name: webapp
        image: scottyc/webapp:latest
        ports:
        - containerPort: 3000
          hostPort: 3000
EOF

Now check our deployment

kubectl get deployments
kubectl get pods
kubectl get services

Expose our service

kubectl expose deployment webapp-deployment --type=LoadBalancer
kubectl get service

kubectl get service will give you the public ip address for the application. It will then be available

Now we move onto the next module here
