Tip/Suggestion: Seeing Default Values

The Seeing Default Values section says that the command "helm inspect ..." and there is no such inspect sub-command, it should be "helm show ...Tip"

4th paragraph, the duplicate installation

In Chapter 2, page 30, it is mentioned that "In Helm 2, instance names were cluster-wide.You could only have an instance named mysite once per cluster. In Helm 3, naming has been changed. Now instance names are scoped to Kubernetes namespaces. We could install two instances named mysite as long as they each lived in a different namespace."

The sites live in different namespaces, but have identical configurations, thus will both be served on localhost:80, both of them exposed by their own load balancer. The first one that was installed is the only one accessible.

Not a grave technical error, but it does contradict the point that you can have the same Helm installation more than once in the same cluster.

Cheers,

Helm supports ranges including =, !=, <, ⇐, >, >=, ^, ~, and -. Different ranges can be combined together using a space or comma to support logical and combinations and | ----------- there is no ⇐, should be <=
