Problem Statement
What is immutable configuration in Kubernetes and why is it beneficial for Deployments?
Explanation
Immutable configuration means you treat your Deployment manifest, container image and config data as unchangeable once released, and instead deploy new versions rather than mutate running ones. This approach improves auditability, rollback safety and reproducibility. By deploying a new image tag or changing spec and applying a new Deployment, you ensure a clean, known state rather than chasing configuration drift.
