You are tasked to create a secret and consume the secret in a pod using environment variables as follow:
Task
* Create a secret named another-secret with a key/value pair; key1/value4
* Start an nginx pod named nginx-secret using container image nginx, and add an environment variable exposing the value of the secret key key 1, using COOL_VARIABLE as the name for the environment variable inside the pod See the solution below.

질문 # 121
Context
An existing web application must be exposed externally.
You must connect to the correct host . Failure to do so may result in a zero score.
[candidate@base] $ ssh ckad00025
An application externally using the URL external.sterling-bengal.local . Any requests starting with / must be routed to the application web-app.
To test the web application's external reachability, run
[candidate@ckad00025]
$ curl http://external.sterling-bengal.local/
or open this URL in the remote desktop's browser.

See the Explanation below for complete solution.
Explanation:
ssh ckad00025
You need to expose the existing app "web-app" externally at:
* Host: external.sterling-bengal.local
* Path: / (and anything starting with /) # route to web-app
In CKAD labs, this is almost always done with an Ingress pointing to the Service web-app.
1) Find where web-app Service lives (namespace + port)
kubectl get svc -A | grep -w web-app
You'll get something like:
<NAMESPACE> web-app ClusterIP ... <PORT>/TCP
Set the namespace:
NS=<NAMESPACE>
Check the service port(s):
kubectl -n $NS get svc web-app -o yaml
Note the service port number (commonly 80).
Also verify it has endpoints (so it actually routes to pods):
kubectl -n $NS get endpoints web-app -o wide
If endpoints are empty, the Service selector doesn't match pods - tell me and I'll give the exact fix. But usually it's fine.
2) Create the Ingress to route / to web-app
Create a manifest (use the service port you saw; I'll assume 80 below):
cat <<'EOF' > web-app-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: web-app-ingress
spec:
rules:
- host: external.sterling-bengal.local
http:
paths:
- path: /
pathType: Prefix
backend:
service:
name: web-app
port:
number: 80
EOF
Apply it:
kubectl -n $NS apply -f web-app-ingress.yaml
Verify:
kubectl -n $NS get ingress web-app-ingress
kubectl -n $NS describe ingress web-app-ingress
If your Service port is not 80, change number: 80 to the correct value and re-apply.
3) Test external reachability (as instructed)
Run exactly:
curl
-i http://external.sterling-bengal.local/
If curl still fails (quick checks)
A) Is there an ingress controller running?
kubectl get pods -A | egrep -i 'ingress|nginx'
kubectl get svc -A | egrep -i 'ingress|nginx'
B) Does Ingress show an address?
kubectl -n $NS get ingress web-app-ingress -o wide
C) Do we have endpoints?
kubectl -n $NS get endpoints web-app -o wide
