@Veki301 why should the defaults be changed? are we sure this does not have any side effects on other environments which are using the defaults?

[Veki301]

it is required for a on-prem HA deployment, current defaults do not work, we should arrange a test on one of the cailleach envs or find a better solution, ill discuss with Julia today
will wait on merging

[lwille]

From what I could find in cailleach, we always seem to override these with e.g. __COTURN_HOST_IP__ or __COTURN_EXT_IP__ - which speaks for the default values being dysfunctional

There's another default on the template level:

    listening-ip={{ default "__COTURN_EXT_IP__" .Values.coturnTurnListenIP }}

If we change the default in the Values to be anything but null, we need to remove the defaults in the template to avoid confusion.

To support having different sets of defaults for different environments, we could introduce a second file, e.g. values-local-testing.yaml, and update the docs to reference both files, e.g. helm ... -f values.yaml -f values-local-testing.yaml.
