Minikube: Deploying Persistent Storage

Issue the command to start Minikube:

sudo minikube start --vm-driver none

Create the blog deployment using the ~/ghost-deploy-template.yaml. Our YAML should look something like this when we're done:

apiVersion: v1
kind: Service
metadata:
    name: blog
    labels:
      app: gblog
spec:
    type: NodePort
    selector:
      app: gblog
    ports:
        - nodePort: 30005
          port: 80
          targetPort: 2368
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: blog-stor
  labels:
    app: gblog
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 3Gi
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: gblog
  labels:
    app: gblog
spec:
  selector:
    matchLabels:
      app: gblog
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: gblog
    spec:
      containers:
          - name: blog-cont
            image: ghost:2.6-alpine
            ports:
            - containerPort: 2368
            volumeMounts:
            - name: blog-vol
              mountPath: "/var/lib/ghost/content"
      volumes:
      - name: blog-vol
        persistentVolumeClaim:
          claimName: blog-stor

Now we can create the deployment:

sudo kubectl create -f ~/ghost-deploy-template.yaml

Verify that it is up and running:

sudo kubectl get pv
sudo kubectl get pvc
sudo kubectl get po

Get the node port address, which will be the TARGET_PORT of blog in the output of this command:

sudo minikube service list

Now we can configure Nginx to proxy to the blog service. Edit the file:

sudo vim /etc/nginx/sites-enabled/default

Around line 50, we need to stick our Minikub IP and port in the location section remove this line

 try_files $uri $uri/ =404;

and replace it with the ip and port from the services command so it looks like this

location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        proxy_pass http://MINIKUB_IP:PORT;
    }

Now let's restart Nginx to implement the new configuration:

sudo systemctl restart nginx
