1. Challenge

   Start the Minikube Cluster (Remember to Use the Correct Driver)

   Issue this command:

   sudo minikube start --vm-driver none
   

2. Challenge

   Using the Provided YAML Files, Create a Volume with a Local Mapping and then a Claim and Pod for that Volume

   Locate the local folder in the cloud_user home directory, and get into it:

   ls
   cd local
   

   In this directory inspect the pv-hostPath-volume.yaml (with cat) and locate the local mapping:

   hostPath:
   path: "/home/cloud_user/html"
   

   Create the directory indicated in the hostPath:

   mkdir /home/cloud_user/html
   

   In this directory create an index.html file:

   echo 'this is the local index' >> /home/cloud_user/html/index.html
   

   Create the volume and PersistentVolumeClaim and ensure that they are bound:

   sudo kubectl apply -f /home/cloud_user/local/pv-hostPath-volume.yaml
   sudo kubectl apply -f /home/cloud_user/local/pv-hostPath-claim.yaml
   
   sudo kubectl get pv  # this output should show the volume status as Available
   sudo kubectl get pvc # this output should show Bound
   

   Now let's create the Nginx pod and then run curl on the pod IP to ensure that the custom index loads:

   sudo kubectl apply -f /home/cloud_user/local/pv-hostPath-pod.yaml
   sudo kubectl get po -o wide
   

   There's going to be an IP address in the output of that command. We need it in this next command:

   curl <IP_ADDRESS>
   

   We should see what we put in the index.html file earlier. Now, to see the power of what we've done here, let's append to that file:

   echo 'this is a new line' >> /home/cloud_user/html/index.html
   

   Then we'll run that curl command again, and see that our new content is showing up -- without having to restart the container!
