Minikube: Deploying to Our Cluster

Issue the command to start Minikube:

sudo minikube start --vm-driver none

We can create the deployment using the file ~/nginx-deploy-template.yaml. Use the Nginx pv-deployment.yaml file as a reference if needed.

Our deployment should look similar to this:

kind: Service
apiVersion: v1
metadata:
    name: nginx-service
    labels:
      app: nginx-volume
spec:
    type: NodePort
    selector:
      app: nginx-volume
    ports:
        - nodePort: 30002
          port: 8080
          targetPort: 80
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: nginx-stor
  labels:
    app: nginx-deploy
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteOnce
  hostPath:
    path: "/home/cloud_user/indexdoc"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nginx-pvc
  labels:
    app: nginx-deploy
spec:
 storageClassName: manual
 accessModes:
   - ReadWriteOnce
 resources:
   requests:
     storage: 3Gi
---
apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx-deploy
spec:
  selector:
    matchLabels:
      app: nginx-deploy
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: nginx-deploy
    spec:
      containers:
          - name: nginx-cont
            image: nginx
            ports:
            - containerPort: 80
            volumeMounts:
            - name: nginx-vol
              mountPath: "/usr/share/nginx/html"
      volumes:
      - name: nginx-vol
        persistentVolumeClaim:
          claimName: nginx-pvc

Run the following to create the index:

mkdir ~/indexdoc
echo 'this is the local index file' > ./indexdoc/index.html

Now let's create the Nginx deployment using kubectl:

sudo kubectl create -f ~/nginx-deployment-template.yaml

We need make sure the Nginx pod is up and running, and get its IP:

sudo kubectl get po -o wide

And now we can run curl on that IP, to see if the index loads:

curl <POD_IP>

The output of that should be the this is the local index file that we put in ./indexdoc/index.html a couple minutes ago.
