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.

Create an Nginx Deployment from the Template

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

Challenge

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 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.
