Minikube: Deploying to Our Cluster
In this hands-on lab we will be creating a deployment from scratch, using a YAML template, and deploying it to our Minikub cluster. Once everything looks like it's up and running, we'll run some tests.

Start the Minikube Cluster Using the Correct Driver
Issue the command to start Minikube:
sudo minikube start --vm-driver none
Create an Nginx Deployment from the Template
We can create the deployment using the file
~/nginx-deploy-template.yaml. Use the Nginx
pv-deployment.yamlfile 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
Create the Index File and Create the Nginx Deployment
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
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
curlon that IP, to see if the index loads:
The output of that should be the this is the local index file that we put in
./indexdoc/index.htmla couple minutes ago.
