Lab Information

The Nautilus DevOps team is planning to deploy some micro services on Kubernetes platform. The team has already set up a Kubernetes cluster and now they want to set up some namespaces, deployments etc. Based on the current requirements, the team has shared some details as below:

Create a namespace named dev and deploy a POD within it. Name the pod dev-nginx-pod and use the nginx image with the latest tag. Ensure to specify the tag as nginx:latest.

Note: The kubectl utility on jump_host is configured to operate with the Kubernetes cluster.

Lab Solutions

Step 1: Create the Namespace

Create the dev namespace

kubectl create namespace dev

Step 2: Create the Nginx Pod in the dev Namespace

# Create the nginx pod in the dev namespace
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Pod
metadata:
  name: dev-nginx-pod
  namespace: dev
spec:
  containers:
  - name: nginx-container
    image: nginx:latest
    ports:
    - containerPort: 80
EOF

Step 3: Verification
Check if the namespace was created:

kubectl get namespaces | grep dev

Check if the pod is running in the dev namespace:

kubectl get pods -n dev

Get detailed information about the pod:

kubectl describe pod dev-nginx-pod -n dev

Check the pod logs to ensure nginx started correctly:

kubectl logs dev-nginx-pod -n dev
