Deploy your application

Now that you have access to the team namespace and have pushed your image to Harbor, you can now deploy your application.

In this case we'll use a demo app called hello. If you like you can clone the repo

git clone https://github.com/redkubes/nodejs-helloworld.git

And then tag and build the image as you have done in lab 5.

Create a Deployment and Service

Create a hello-svc.yaml file and copy/paste the following 2 Kubernetes manifests:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-svc
spec:
  replicas: 1
  selector:
    matchLabels:
      app: hello-svc
  template:
    metadata:
      labels:
        app: hello-svc
    spec:
      containers:
        - name: hello-svc
          image: harbor.<your-domain>/<team-name>/<image-name>:<tag>
          resources:
            limits:
              memory: '128Mi'
              cpu: '200m'
            requests:
              memory: '64Mi'
              cpu: '100m'
          securityContext:
            runAsUser: 1001
          ports:
            - containerPort: 8080
---
apiVersion: v1
kind: Service
metadata:
  name: hello-svc
spec:
  selector:
    app: hello-svc
  ports:
    - port: 80
      targetPort: 8080

Now apply the manifest to Kubernetes:

kubectl apply -f hello-svc.yaml

Check to see if the pod is running and the service has been created:

kubectl get pod

kubectl describe svc hello

note

The example here is only a very simplified one. You can dive into the world of Kubernetes deployments, or you can ask your platform administrator to enable Knative Serving. Knative will then take care of auto scaling for you. We will also soon release a new feature that will help to remove the struggle of creating and managing Kubernetes manifests. Stay tuned!
