Question 6: Multi-Container Deployment

Create a Deployment with two containers per Pod, specific images, and specific labels.

Implement the following in Namespace project-tiger:

Create a Deployment named deploy-important with 3 replicas
The Deployment and its Pods should have label id=very-important
First container named container1 with image nginx:1-alpine
Second container named container2 with image registry.k8s.io/pause:3.9

Hint 1

A Pod template's own labels don't automatically inherit from the Deployment's metadata labels — they're two separate labels: fields in the manifest, both need setting. And the Deployment's selector has to agree with whatever you put in the Pod template's labels, or the object won't even apply.

Hint 2

Multiple containers in one Pod just means multiple entries in the same list, each with its own name and image — no separate Pod or Deployment needed per container.
