helm_template

ADDITIONAL INFORMATION

Sometimes a chart needs to be different under under different conditions so a template is used. While an Ansible content developer could use the template module an Jinja2, some may already have or be forced to work with Helm charts.
Ansible should address this scenario in a more Helm-native way with a module that is the functional equivalent of the `helm template command.

This module should use parameters like helm and other modules for cohesive and consistent operation with Helm3 automation.
