@andresmgot I've committed the changes and verified it works against the setup i have, the example-tests are failing in the CI server i was unable to run them against my local cluster nor our environment. Do the tests require a specific cluster setup?

Thanks for the PR @ddoowa!. The error in the CI was not related to your changes (just some flakiness there).

Thanks for sorting that out @andresmgot, Any ETA on how soon this can be merged?

now :) (I was just waiting for the CI to finish)
