When such a drive is connected to a computer running Linux, it can be found in the device directory <em>/dev/</em> under the name <em>sdX</em>, where <em>X</em> is a letter changing for each drive.

Applications deployed on a Kubernetes cluster run inside containers. As a consequence, their file system is that of the container, which means that if the container is removed, the data it contained is lost.

Consequently, the CI pipeline is by default not in a position to include credentials in the dockerized application, which most likely prevents the latter from running as intended.

When using kubectl apply using an already applied and unchanged manifest file, nothing happens on the Kubernetes cluster. However, deployments can be configured so as to always pull a new version image upon restart. This is achieved using the, <code>imagePullPolicy: Always</code> parameter:
