Nice tutorial for seeing HOW it can be done, but needs more

Undertanding how to update wordpress, plugins and themes is pretty important. This stack is great if you only want to use vanilla wordpress, and have no storage.

- an example using buckets for persistent storage would help users a lot
- an example of how to add themes/plugins using this deploystack makes this actually useful
- I assume wordpress will stay up to date with the gcr image, but what happens if Google stops updating the image. how do users manage wordpress updates themselves?
