LTGM. I like this change. It's a little less verbose overall. I'll make the same changes to Persistent Volumes after this is merged. Thanks for the heads up.

LGTM. Thanks.

What about all the examples - I dont see any .json or .yaml files.

I see at least 3 files using v1b3 and volumes:

./examples/mysql-wordpress-pd/v1beta3/mysql.yaml
./examples/mysql-wordpress-pd/v1beta3/wordpress.yaml
./examples/cassandra/v1beta3/cassandra-controller.yaml

examples updated. (fwiw, I guess we need to expand coverage of our unit test to include those files, since that unit test passes)

The problem with examples_test.go is that this is valid:

kind: Pod
apiVersion: v1beta3
metadata:
  name: mypod
none:
  of:
    these:
      fields:
        exist: "but the test still passes"

Unless validation catches a bad value, the tests will pass.

LGTM
