Using Storage in Docker Kubernetes Service

Kubernetes has the ability to provide external storage for your containerized applications. In this lab, you will be able to work with Kubernetes storage hands-on, designing your own solution to a real-world problem using Kubernetes features. This will help you familiarize yourself with Kubernetes features, such as volumes, and PersistentVolumes.

Challenge

Create a Persistent Volume
1. Create a PersistentVolume with a type of hostPath that stores data at the path /etc/output on the host.
2. Set the capacity to 1Gi.
Note: that you will need to create and use a custom StorageClass that supports volume resizing since you will need to resize the PersistentVolumeClaim later. For this exercise, you can use the provisioner kubernetes.io/no-provisioner.
Challenge

Create a Persistent Volume Claim.
1. Create a PersistentVolumeClaim that will bind to the PersistentVolume. Give it a capacity of 100Mi.
Challenge

Create a Pod That Will Output Data to the Persistent Volume
1. Create a pod that uses the image busybox and sends a response to output.log.
```
sh -c while true; do echo "Successfully written to log." >> /output/output.log; sleep 10; done
```
2. Mount the PersistentVolumeClaim, so that the data written to /output/output.log by the container shows up in the persistent volume storage.
Challenge

Resize the Persistent Volume Claim
1. Increase the size of the PersistentVolumeClaim to 200Mi.
