What is ConfigMap and how was it used in your work?

ConfigMap is an object in Kubernetes that allows storing configuration data as key-value pairs separately from containers. This is convenient for managing application settings without the need to rebuild the image.

In my work, I used ConfigMap to store database connection parameters and logging settings. Example of usage:

apiVersion: v1
kind: ConfigMap
metadata:
  name: app-config
data:
  DB_HOST: "db.example.com"
  LOG_LEVEL: "debug"

In the Pod manifest, these values are mounted as environment variables or files, allowing the application to dynamically receive configuration.
