💡 Hint

Common Mistakes

Using 'Pod' instead of 'Deployment' will create a single pod, not a deployment.

Using 'Service' will create a network endpoint, not a deployment.

The kind field defines the type of Kubernetes object. For creating deployments, it must be Deployment.

💡 Hint

Common Mistakes

Using words like 'ten' instead of numbers causes errors.

Negative numbers are not allowed for replicas.

The replicas field specifies how many pod copies to run. It must be a positive integer like 3.

Fix the error in the container image name.

Kubernetes

containers:
- name: myapp-container
  image: [1]

Drag options to blanks, or click blank then click option'

Cnginx latest

Dnginx_latest

Attempts:

💡 Hint

Common Mistakes

Using slash '/' instead of colon ':' causes image pull errors.

Using spaces in image names is invalid.

The container image name must use a colon : to separate the image name and tag, like nginx:latest.

hard

Fill both blanks to correctly specify container ports and labels.

Kubernetes

spec:
  template:
    metadata:
      labels:
        app: [1]
    spec:
      containers:
      - name: myapp-container
        image: nginx:latest
        ports:
        - containerPort: [2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using different labels breaks pod selection.

Using wrong port numbers causes connection issues.

The label app should match the selector label, here myapp. The common HTTP port for nginx is 80.

5fill in blank

hard

Fill all three blanks to complete the deployment spec with correct keys and values.

Kubernetes

apiVersion: apps/v1
kind: Deployment
metadata:
  name: [1]
spec:
  replicas: [2]
  selector:
    matchLabels:
      app: [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mismatched labels cause deployment to fail selecting pods.

Using zero or negative replicas stops pods from running.

The deployment name is my-deployment. The replicas count is 3. The label app must match the pod template label, here myapp.
