Lessons Learned

• When you make significant change to a helm chart, sometimes better to delete and apply (vs apply over the top) to make sure you pick up changes. this is especially true if changes where to the test piece of the chart. Even an apply doesn't seem to pick up the changes, without doing a delete first.
