First code example

There is a command `cp /cni/loopback /opt/cin/bin/ || true`.

I'm fairly certain that the `/opt/cin/bin/` directory path should be `/opt/cni/bin/`.

So the command should be `cp /cni/loopback /opt/cni/bin/ || true`.

In the kindle edition there is a diagram which features a box labeled ‘Promethrus Adaptor’, which should be ‘Prometheus Adaptor’.

Access Modes 1st paragraph

The description for RWO, ROX, and RWX it points out Pods and is incorrect is Nodes.
From the technical documentation https://kubernetes.io/docs/concepts/storage/persistent-volumes/#access-modes

A single Pod can read and write to the volume.

Multiple Pods can read the volume.

Multiple Pods can read and write to the volume.

It should be Node(s) not Pod(s)

A single Node can read and write to the volume.

Multiple Nodes can read the volume.

Multiple Nodes can read and write to the volume.

3rd Observability

The statement reads " This includes at the system and application layers"

I think "at" is a typo, that is not needed, the statement should read
"This includes the system and application layers"

3rd pararaph "Secret Managment"

the line that reads " we can ensure data is encrypted before it is stored (encryption at rest)

I believe it should read " data is encrypted when it is stored
