Microservices - Orchestration with Kubernetes

Given this YAML snippet for a pod:

apiVersion: v1
kind: Pod
metadata:
  name: myapp-pod
spec:
  containers:
  - name: myapp-container
    image: nginx:latest
    ports:
    - containerPort: 80

What will kubectl get pods myapp-pod show after creation?

ANAME READY STATUS RESTARTS AGE myapp-pod 1/1 Completed 0 0s

BError: pod not found

CNAME READY STATUS RESTARTS AGE myapp-pod 0/1 Pending 0 0s

DNAME READY STATUS RESTARTS AGE myapp-pod 1/1 Running 0 0s

Step-by-Step Solution

Solution:

Step 1: Understand pod creation from YAML
The YAML defines a pod with one container running nginx, exposing port 80.
Step 2: Predict pod status after creation
Immediately after creation, the pod should be running with 1 container ready, so status is Running and READY is 1/1.
Final Answer:
NAME READY STATUS RESTARTS AGE myapp-pod 1/1 Running 0 0s -> Option D
Quick Check:
Pod created and running = READY 1/1 Running [OK]

Quick Trick: New pod with valid image shows READY 1/1 Running [OK]

Common Mistakes:

MISTAKES

Expecting Pending status without reason
Confusing Completed with Running
Assuming pod not found immediately after creation
