Step-by-Step Solution
Solution:
Step 1: Understand restart policies in kubectl run
Using--restart=Nevercreates a Pod with restart policy 'Never', so it won't restart automatically.Step 2: Evaluate each option
kubectl run webserver --image=nginx --restart=Never correctly uses--restart=Never. kubectl run webserver --image=nginx --restart=Always uses--restart=Alwayswhich creates a Deployment that restarts Pods. kubectl create pod webserver --image=nginx --restart=Never uses invalid syntax. kubectl run webserver --image=nginx creates a Deployment by default.Final Answer:
kubectl run webserver --image=nginx --restart=Never -> Option DQuick Check:
--restart=Never means Pod won't auto-restart [OK]
Quick Trick: Use --restart=Never to prevent Pod auto-restart on failure [OK]
Common Mistakes:
- Using default restart which creates Deployment
- Confusing --restart=Always with no restart
- Trying invalid commands like kubectl create pod
