When deploying applications in a Kubernetes (k8s) cluster, different environments like Development (Dev), Quality Assurance (QA), Staging, and Production (Prod) may require different configurations. Managing these configurations efficiently is crucial for seamless application deployment.
Updating configuration files traditionally requires:
Since this process is cumbersome, decoupling configurations from image content ensures better portability and maintainability of containerized applications.
A ConfigMap is a Kubernetes API object used to store non-sensitive, unencrypted configuration data separately from the application logic.
✔️ Allows decoupling configuration from the application image.
✔️ Stores non-sensitive configuration data.
✔️ Helps in managing environment-specific settings.
✔️ Supports fine-grained storage, either as individual properties or entire configuration files.
✔️ Not a replacement for a traditional properties file.
