Thanks for working on and fixing this! I'm planning to add a complex example to the automated example tests to make sure we can test all of these sorts of features and be sure that they are configured properly. Right now the integration tests only focus on testing the features used by the default install.

Would really like to see it merged! @jamestutton this looks like a very simple and straightforward fix. Do you plan to submit it anytime soon?

Thanks!

Hello @jamestutton,
Thank for your PR.
I'll close it as extraVolumes was fixed in #245 and Service Account was implemented in another way in #265.
