Signed-off-by: Michael Nelson minelson@vmware.com

Description of the change

This change uses the new support for custom default values files so that:

• if a single custom default values file is found in the chart, it is presented to the user so that authors can control the default values presented to users.

Note that, since it is just an overlay over the charts values.yaml, it can be used both to present a simpler selection of options to users, or to present a different set of default values.

Benefits

Fulfills use-case 1 of #5692 .

Possible drawbacks

Applicable issues

• ref Support additional default values from a package #5692

Additional information

Using the custom default values in the simplechart, before the user makes any changes, they are presented with those values (only):

Any changes made are diffed against the custom default:
