Summary

This chapter delved into the fundamental concepts of managing configuration within Kubernetes. We explored the critical distinction between ConfigMaps and Secrets, understanding their respective roles in handling non-sensitive and sensitive data. By effectively utilizing these Kubernetes resources, you can significantly enhance application portability and security.

We learned how to create and manage both ConfigMaps and Secrets, employing both imperative and declarative approaches. You discovered how to inject configuration data into Pods using environment variables and volume mounts, ensuring seamless access to application settings.

To protect sensitive information, we emphasized the importance of implementing robust security measures beyond base64 encoding. By combining RBAC, encryption, and external secret management solutions, you can significantly strengthen the security posture of your Kubernetes environment.
