Custom Logger

Example chart configuration

This section provides an example of a Helm Chart configuration for a Java application that utilizes a custom logger configuration stored in a ConfigMap. The example demonstrates how to properly define and attach the logger configuration file to the application, enabling centralized logging management without modifying the application code.
