Volume type in Kubernetes is a somewhat complex item because there is no field called "volume type"

It can be one of many types that are manually listed in the spec 

"secret" and "configMap" are two examples but "bind" is not so the example is misleading. The comma is misleading as well, we expect a string without quotes (although we say we expect a regex)

To fix this bug:

The short name : no change (Volume type) 

The long name should say

Volume Type (e.g. secret, configMap, hostPath) is:

The example should say:

hostPath
