Kubernetes Secrets are specifically intended to hold confidential dat a. Which API object should be used to hold non-confidential data?

In Kubernetes, a ConfigMap is the designated API object for storing non-confidential configuration data as key-value pairs. This decouples configuration artifacts from container image content, making applications more portable. Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume. This is in direct contrast to Secrets, which are designed specifically for sensitive data like passwords, tokens, or keys, and are stored with additional security measures like base64 encoding.

A. CNI (Container Network Interface) is a specification for configuring network interfaces for Linux containers, not for storing application data.
B. CSI (Container Storage Interface) is a standard for exposing block and file storage systems to containerized workloads, not for configuration data.
D. RBAC (Role-Based Access Control) is an authorization mechanism used to regulate access to Kubernetes API resources, not to store data.
