In this article, we will explore how to define an item in a Kubernetes ConfigMap as optional. This is essential to prevent deployment issues, such as `CreateContainerConfigError`, when the ConfigMap is not available. We’ll also discuss scenarios where optional ConfigMap values are useful, such as setting environment variables like proxy settings only when needed. A sample application will demonstrate how to implement this in your YAML configurations.
