Docker & Kubernetes in Real Production: Need a Real Day-to-Day Example

I’m working as an Azure Cloud Engineer (ex-IBM), but I haven’t worked hands-on with Docker or Kubernetes in a real production environment. In interviews, everyone asks for day-to-day real-time examples, and I’m not able to answer confidently.

Could someone please share one solid real production scenario— • What kind of application it was • Why Docker was used • What daily tasks you handled • How you used Kubernetes (deployment, service, scaling, etc.)

For example, something like: Writing a Dockerfile for an app → pushing the image to ACR → creating Kubernetes deployment.yml and service.yml → deploying to AKS.

If anyone can share a realistic example I can explain during interviews, it would really help. Thanks in advance!
