Overview
ConfigMaps allow you to decouple environment-specific configuration from your container images, making your applications easier to port. They are ideal for storing configuration files, command-line arguments, environment variables, and other configuration artifacts.
Usage
- Environment Variables: Injecting configuration directly into a container's environment.
- Command-line Arguments: Passing configuration to the application's entry point.
- Configuration Files in a Volume: Mounting the ConfigMap as a file system inside the container.
Limitations
ConfigMaps are not intended to store sensitive information. For secrets like passwords or API keys, you should use the Secret object instead.
