During my CKA preparation, I realized that one of the biggest differences between knowing Kubernetes and working efficiently with Kubernetes was mastering kubectl.
In the beginning, I understood concepts like Pods, Deployments, Services, and Storage. However, when solving hands-on labs and mock exams, I often found myself spending too much time trying to remember commands or searching for syntax.
Over time, I built a personal list of kubectl commands that I used repeatedly during practice sessions. These commands helped me troubleshoot faster, manage workloads more efficiently, and save valuable time during the exam.
Even after earning the Certified Kubernetes Administrator (CKA) certification, many of these commands remain part of my daily workflow as a DevOps Engineer.
In this article, I’ll share my top 50 kubectl commands, along with the commands I believe every Kubernetes administrator should master.
Why kubectl Matters
kubectl is the primary interface for interacting with Kubernetes clusters.
Whether you’re:
Deploying applications
Managing resources
Troubleshooting issues
Monitoring workloads
Configuring networking
Managing storage
kubectl becomes your most important tool.
The faster and more comfortable you are with kubectl, the more effective you’ll be both during the CKA exam and in real-world Kubernetes administration.
If You Only Learn 10 Commands, Learn These First
If you’re new to Kubernetes or preparing for CKA, start with these commands:
kubectl get pods -A
kubectl describe pod <pod-name>
kubectl logs <pod-name>
kubectl exec -it <pod-name> -- sh
kubectl get events
kubectl get nodes
kubectl get svc
kubectl rollout undo deployment/<deployment-name>
kubectl explain deployment.spec
kubectl top pods
I used these commands almost every day during preparation.
Cluster Administration Commands
kubectl cluster-info
Check Kubernetes Version
kubectl version --short
List Nodes
kubectl get nodes
Describe Node
kubectl describe node <node-name>
View Component Status
kubectl get componentstatuses
Pod Management Commands
List Pods
kubectl get pods
List Pods Across All Namespaces
kubectl get pods -A
Wide Output
kubectl get pods -o wide
Describe Pod
kubectl describe pod <pod-name>
Delete Pod
kubectl delete pod <pod-name>
Create Pod
kubectl run nginx --image=nginx
Export Pod YAML
kubectl get pod <pod-name> -o yaml
Edit Pod
kubectl edit pod <pod-name>
Execute Command Inside Pod
kubectl exec -it <pod-name> -- sh
Copy Files
kubectl cp <pod-name>:/tmp/file .
Logging and Troubleshooting Commands
View Logs
kubectl logs <pod-name>
Follow Logs
kubectl logs -f <pod-name>
View Previous Logs
kubectl logs --previous <pod-name>
List Events
kubectl get events
Sort Events by Timestamp
kubectl get events --sort-by=.metadata.creationTimestamp
Real CKA Troubleshooting Example
One of the most common issues during CKA preparation was a Pod stuck in a CrashLoopBackOff state.
My troubleshooting workflow looked like this:
kubectl get pods
kubectl describe pod <pod-name>
kubectl logs <pod-name>
In many cases, these three commands were enough to identify the root cause.
This simple workflow saved me a lot of time during practice exams.
Deployment Commands
List Deployments
kubectl get deployments
Create Deployment
kubectl create deployment nginx --image=nginx
Scale Deployment
kubectl scale deployment nginx --replicas=5
Update Image
kubectl set image deployment/nginx nginx=nginx:latest
Check Rollout Status
kubectl rollout status deployment/nginx
Rollout History
kubectl rollout history deployment/nginx
Rollback Deployment
kubectl rollout undo deployment/nginx
Service and Networking Commands
List Services
kubectl get svc
Describe Service
kubectl describe svc <service-name>
Expose Deployment
kubectl expose deployment nginx --port=80
Port Forward
kubectl port-forward pod/<pod-name> 8080:80
View Endpoints
kubectl get endpoints
List Network Policies
kubectl get networkpolicy
Namespace Commands
List Namespaces
kubectl get ns
Create Namespace
kubectl create namespace dev
Switch Namespace
kubectl config set-context --current --namespace=dev
Delete Namespace
kubectl delete ns dev
ConfigMaps and Secrets
List ConfigMaps
kubectl get configmaps
Create ConfigMap
kubectl create configmap app-config --from-literal=env=prod
List Secrets
kubectl get secrets
Create Secret
kubectl create secret generic db-secret \
--from-literal=password=admin123
Storage Commands
List Persistent Volumes
kubectl get pv
List Persistent Volume Claims
kubectl get pvc
Describe PVC
kubectl describe pvc <pvc-name>
Resource Monitoring Commands
Node Resource Usage
kubectl top nodes
Pod Resource Usage
kubectl top pods
Namespace Resource Usage
kubectl top pods -n kube-system
Commands I Wish I Had Learned Earlier
Looking back, these commands would have saved me significant time if I had mastered them earlier:
kubectl explain deployment.spec
kubectl get events
kubectl top pods
kubectl rollout history deployment/nginx
kubectl auth can-i create deployments
The kubectl explain command was particularly useful because it helped me understand resource structures directly from the terminal.
My Favorite CKA Productivity Commands
Generate YAML Quickly
Instead of manually writing YAML, I frequently used:
kubectl run nginx \
--image=nginx \
--dry-run=client \
-o yaml
Generate Deployment YAML
kubectl create deployment nginx \
--image=nginx \
--dry-run=client \
-o yaml
Explain Resource Fields
kubectl explain deployment.spec.template.spec
This command became one of my favorites during preparation.
My kubectl Setup for CKA
One of the first things I configured in every lab environment was:
alias k=kubectl
This allowed me to type:
k get pods
instead of:
kubectl get pods
It seems minor, but over hundreds of commands, it saves a surprising amount of time.
My Personal Learning Strategy
I didn’t try to memorize 50 commands overnight.
Instead, I followed a simple process:
Learn
Understand what the command does.
Practice
Use it repeatedly in labs.
Troubleshoot
Apply it while fixing real problems.
Repeat
Build muscle memory through repetition.
Eventually, many commands became second nature.
Final Thoughts
The difference between a beginner Kubernetes engineer and an experienced administrator is often not knowledge — it’s speed.
Speed comes from repetition.
The more comfortable you become with kubectl, the less time you’ll spend remembering commands and the more time you’ll spend solving problems.
These 50 commands helped me during my CKA preparation and continue to help me in real-world Kubernetes administration every day.
If you’re preparing for the CKA exam, start practicing them today.
Your future self will thank you.
