Task Summary
Create an Ingress named echo in the sound-repeater namespace that:
* Routes requests to /echo on host example.org
* Forwards traffic to service echoserver-service
* Uses service port 8080
* Verification should return HTTP 200 using curl
# Step-by-Step Answer
1## SSH into the correct node
As shown in the image:
bash
CopyEdit
ssh cka000024
## Skipping this will result in a ZERO score!
2## Verify the namespace and service
Ensure the sound-repeater namespace and echoserver-service exist:
kubectl get svc -n sound-repeater
Look for:
echoserver-service ClusterIP ... 8080/TCP
3## Create the Ingress manifest
Create a YAML file: echo-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: echo
namespace: sound-repeater
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
rules:
- host: example.org
http:
paths:
- path: /echo
pathType: Prefix
backend:
service:
name: echoserver-service
port:
number: 8080
4## Apply the Ingress resource
kubectl apply -f echo-ingress.yaml
5## Test with curl as instructed
Use the exact verification command:
curl -o /dev/null -s -w "%{http_code}\n"
http://example.org/echo
# You should see:
200
# Final Answer Summary
ssh cka000024
kubectl get svc -n sound-repeater
# Create the Ingress YAML
cat <<EOF > echo-ingress.yaml
apiVersion: networking.k8s.io/v1

Task Summary
You need to:
* SSH into cka000046
* Create a StorageClass named local-path using the provisioner rancher.io/local-path
* Set the volume binding mode to WaitForFirstConsumer
* Make this StorageClass the default
Step-by-Step Solution
1## SSH into the correct host
ssh cka000046
## Required. Skipping this = zero score
2## Create a StorageClass YAML file
Create a file named local-path-sc.yaml:
cat <<EOF > local-path-sc.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-path
annotations:
storageclass.kubernetes.io/is-default-class: "true"
provisioner: rancher.io/local-path
volumeBindingMode: WaitForFirstConsumer
EOF
# This:
* Sets WaitForFirstConsumer (as required)
* Marks the class as default using the correct annotation
3## Apply the StorageClass
kubectl apply -f local-path-sc.yaml
4## Verify it's the default StorageClass
kubectl get storageclass
You should see local-path with a (default) marker:
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION
AGE
local-path rancher.io/local-path Delete WaitForFirstConsumer false 10s
Final Command Summary
ssh cka000046
cat <<EOF > local-path-sc.yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-path
annotations:
storageclass.kubernetes.io/is-default-class: "true"
provisioner: rancher.io/local-path
volumeBindingMode: WaitForFirstConsumer
EOF
kubectl apply -f local-path-sc.yaml
kubectl get storageclass

Correct Answer:

kubectl get pods --sort-by=.metadata.name
