Creating Pods with kubectl in Kubernetes - Try It Yourself

Creating Pods with kubectl

📖 Scenario: You are working as a DevOps engineer managing containerized applications. You need to create a simple Pod in Kubernetes to run a basic web server container.

🎯 Goal: Learn how to create a Kubernetes Pod using kubectl commands and YAML configuration files step-by-step.

📋 What You'll Learn

Create a YAML file defining a Pod named web-pod running the nginx container

Add a label app: web to the Pod

Use kubectl to create the Pod from the YAML file

Verify the Pod is running using kubectl get pods

💡 Why This Matters

🌍 Real World

Creating Pods is a fundamental task in deploying containerized applications on Kubernetes clusters.

💼 Career

DevOps engineers and site reliability engineers often create and manage Pods to run application workloads reliably.

1

Create the Pod YAML file

Create a file named web-pod.yaml with the following content exactly: a Pod named web-pod running the nginx container and labeled with app: web.

Kubernetes

# Create the YAML file content for the Pod
# Your code here

Need a hint?

Use apiVersion: v1, kind: Pod, and define metadata with name and labels. Under spec, add one container named nginx with image nginx.

2

Create the Pod using kubectl

Run the kubectl create -f web-pod.yaml command to create the Pod from the YAML file you made.

Kubernetes

apiVersion: v1
kind: Pod
metadata:
  name: web-pod
  labels:
    app: web
spec:
  containers:
  - name: nginx
    image: nginx

# Run the kubectl command below
# Your code here

Need a hint?

Use the kubectl create -f command followed by your YAML file name to create the Pod.

3

Check the Pod status

Use the command kubectl get pods to list all Pods and check that web-pod is created and running.

Kubernetes

apiVersion: v1
kind: Pod
metadata:
  name: web-pod
  labels:
    app: web
spec:
  containers:
  - name: nginx
    image: nginx

kubectl create -f web-pod.yaml

# Run the command to list pods
# Your code here

Need a hint?

Simply run kubectl get pods to see the list of Pods and their status.

4

Verify the Pod is running

Look at the output of kubectl get pods and confirm that the Pod named web-pod has the status Running. Write a print statement that outputs exactly: web-pod is Running if the Pod is running.

Kubernetes

apiVersion: v1
kind: Pod
metadata:
  name: web-pod
  labels:
    app: web
spec:
  containers:
  - name: nginx
    image: nginx

kubectl create -f web-pod.yaml

kubectl get pods

# Print the confirmation message below
# Your code here

Need a hint?

Use print("web-pod is Running") to show the Pod status confirmation.
