Microservices - Orchestration with Kubernetes

You deployed a microservice with Kubernetes, but it keeps crashing. The YAML file has this snippet:

spec:
  containers:
  - name: app
    image: myapp:v1
    ports:
    - containerPort: 80
  restartPolicy: Never

What is the problem and how to fix it?

AThe pod name is missing; add metadata name

BThe containerPort is wrong; change it to 8080

CThe image version is invalid; update to 'v2'

DThe restartPolicy 'Never' stops restarts; change it to 'Always' to fix

Step-by-Step Solution

Solution:

Step 1: Identify restartPolicy effect
Setting restartPolicy: Never means Kubernetes will not restart the pod if it crashes.
Step 2: Fix by changing restartPolicy
Changing restartPolicy to Always lets Kubernetes restart the pod automatically to keep it running.
Final Answer:
The restartPolicy 'Never' stops restarts; change it to 'Always' to fix -> Option D
Quick Check:
restartPolicy 'Always' enables auto-restart [OK]

Quick Trick: Use restartPolicy 'Always' to auto-restart pods [OK]
