Extensibility
The Ignition Helm Chart was designed to ensure that you have the right hooks to customize your deployment to your needs. This deep-dive will explore the features of the chart that make it easier to extend and customize.
Extra Objects Support​
The extraObjects value allows you to define arbitrary Kubernetes resources that will be rendered into the final manifest and applied with your release. This field also supports templating, allowing you to leverage the built-in chart helpers to make your resources more dynamic.
