Question 66

Score: 7%

Task
Create a new nginx Ingress resource as follows:
* Name: ping
* Namespace: ing-internal
* Exposing service hi on path /hi using service port 5678

Question 67

Check to see how many worker nodes are ready (not including nodes tainted NoSchedule) and write the number to /opt/KUCC00104/kucc00104.txt.

Question 68

You must connect to the correct host.
Failure to do so may result in a zero score.
[candidate@base] $ ssh Cka000047
Task
A MariaDB Deployment in the mariadb namespace has been deleted by mistake. Your task is to restore the Deployment ensuring data persistence. Follow these steps:
Create a PersistentVolumeClaim (PVC ) named mariadb in the mariadb namespace with the following specifications:
Access mode ReadWriteOnce
Storage 250Mi
You must use the existing retained PersistentVolume (PV ).
Failure to do so will result in a reduced score.
There is only one existing PersistentVolume .
Edit the MariaDB Deployment file located at ~/mariadb-deployment.yaml to use PVC you created in the previous step.
Apply the updated Deployment file to the cluster.
Ensure the MariaDB Deployment is running and stable.

Correct Answer:

Task Overview
You're restoring a MariaDB deployment in the mariadb namespace with persistent data.
# Tasks:
* SSH into cka000047
* Create a PVC named mariadb:
* Namespace: mariadb
* Access mode: ReadWriteOnce
* Storage: 250Mi
* Use the existing retained PV (there's only one)
* Edit ~/mariadb-deployment.yaml to use the PVC
* Apply the deployment
* Verify MariaDB is running and stable
Step-by-Step Solution
1## SSH into the correct host
ssh cka000047
## Required - skipping = zero score
2## Inspect the existing PersistentVolume
kubectl get pv
# Identify the only existing PV, e.g.:
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS
mariadb-pv 250Mi RWO Retain Available <none> manual
Ensure the status is Available, and it is not already bound to a claim.
3## Create the PVC to bind the retained PV
Create a file mariadb-pvc.yaml:
cat <<EOF > mariadb-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mariadb
namespace: mariadb
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 250Mi
volumeName: mariadb-pv # Match the PV name exactly
EOF
Apply the PVC:
kubectl apply -f mariadb-pvc.yaml
# This binds the PVC to the retained PV.
4## Edit the MariaDB Deployment YAML
Open the file:
nano ~/mariadb-deployment.yaml
Look under the spec.template.spec.containers.volumeMounts and spec.template.spec.volumes sections and update them like so:
Add this under the container:
yaml
CopyEdit
volumeMounts:
- name: mariadb-storage
mountPath: /var/lib/mysql
And under the pod spec:
volumes:
- name: mariadb-storage
persistentVolumeClaim:
claimName: mariadb
# These lines mount the PVC at the MariaDB data directory.
5## Apply the updated Deployment
kubectl apply -f ~/mariadb-deployment.yaml
6## Verify the Deployment is running and stable
kubectl get pods -n mariadb
kubectl describe pod -n mariadb <mariadb-pod-name>
# Ensure the pod is in Running state and volume is mounted.
# Final Command Summary
ssh cka000047
kubectl get pv # Find the retained PV
# Create PVC
cat <<EOF > mariadb-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: mariadb
namespace: mariadb
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 250Mi
volumeName: mariadb-pv
EOF
kubectl apply -f mariadb-pvc.yaml
# Edit Deployment
nano ~/mariadb-deployment.yaml
# Add volumeMount and volume to use the PVC as described
kubectl apply -f ~/mariadb-deployment.yaml
kubectl get pods -n mariadb
