Using Container Volume Storage in Kubernetes
Kubernetes offers a variety of tools to help you manage external storage for your containers. In this lab, you will have a chance to work with Kubernetes storage volumes, in the form of both ephemeral volumes and Persistent Volumes.

Challenge
Add an Ephemeral Volume
The application is managed by the
app-processing
Deployment in thedefault
Namespace.The application needs to write some temporary data, but it cannot write directly to the container file system because it is set as read-only. Use a volume to create a temporary storage location at
/tempdata
. -
Challenge
Add a Persistent Volume
The application is managed by the
app-processing
Deployment in thedefault
Namespace. Use a PersistentVolume to mount data from the k8s host to the application's container. The data is located at/etc/voldata
on the host. Set up the PersistentVolume to access this data using directory mode.For the PersistentVolume, set a capacity of
1Gi
. Set the access mode toReadWriteOnce
, and set the storage class tohost
.For the PersistentVolumeClaim, set the storage request to
100Mi
. Mount it to/data
in the container.Note: The application is set up to read data from the PersistentVolumeClaim's mounted location, then write it to the ephemeral volume location, and read it back from the ephemeral volume to the container log. This means that if everything is set up properly, you see the
Hive Key
data in the container log!
