ConfigMaps allow you to decouple configuration artifacts from image content to keep containerized applications portable.
ConfigMaps bind configuration files, command-line arguments, environment variables, port numbers, and other configuration artifacts to your Pods' containers and system components at runtime. ConfigMaps allow you to separate your configurations from your Pods and components, which helps keep your workloads portable, makes their configurations easier to change and manage, and prevents hardcoding configuration data to Pod specifications.
ConfigMaps are useful for storing and sharing non-sensitive, unencrypted configuration information. To use sensitive information in your clusters, you must use Secrets.
