1) Connect to the correct host
ssh cks000028
sudo -i
(If hostname differs in your exam, use the one shown in the question banner.)
2) Edit the API server static pod manifest
API server is a static pod in kubeadm.
vi /etc/kubernetes/manifests/kube-apiserver.yaml
3) Configure API server to enable auditing
Inside the command: section, ensure ALL of the following flags exist
(add them if missing, modify if present).
3.1 Use the given audit policy file
- --audit-policy-file=/etc/kubernetes/logpolicy/audit-policy.yaml
3.2 Store audit logs at the required location
- --audit-log-path=/var/log/kubernetes/audit-logs.txt
3.3 Retain a maximum of 2 log files
- --audit-log-maxbackup=2
3.4 Retain logs for 10 days
- --audit-log-maxage=10
✅ Example (your file may have more flags — that’s fine):
- command:
- kube-apiserver
- --audit-policy-file=/etc/kubernetes/logpolicy/audit-policy.yaml
- --audit-log-path=/var/log/kubernetes/audit-logs.txt
- --audit-log-maxbackup=2
- --audit-log-maxage=10
Save and exit:
wq
???? The API server will auto-restart (static pod).
Optional quick check:
docker ps | grep kube-apiserver
4) Edit and EXTEND the audit policy
Open the given basic policy:
vi /etc/kubernetes/logpolicy/audit-policy.yaml
The file already contains rules for what NOT to log.
You must ADD rules BELOW them (do not delete existing ones).
5) Add the required audit rules (EXACT ORDER)
Append the following rules in this order ⬇️
(order matters in audit policies).
5.1 Log namespaces interactions at RequestResponse
- level: RequestResponse
resources:
- group: ""
resources: ["namespaces"]
5.2 Log deployment request bodies in namespace webapps
- level: RequestResponse
namespaces: ["webapps"]
resources:
- group: "apps"
resources: ["deployments"]
5.3 Log ConfigMap and Secret interactions (all namespaces) at Metadata
- level: Metadata
resources:
- group: ""
resources: ["configmaps", "secrets"]
5.4 Log all other requests at Metadata
⚠️ This must be LAST
- level: Metadata
5.5 Final audit-policy.yaml should END like this
# (existing "do not log" rules above)
- level: RequestResponse
resources:
- group: ""
resources: ["namespaces"]
- level: RequestResponse
namespaces: ["webapps"]
resources:
- group: "apps"
resources: ["deployments"]
- level: Metadata
resources:
- group: ""
resources: ["configmaps", "secrets"]
- level: Metadata
Save and exit:
wq
6) Make sure API server uses the EXTENDED policy
Touch the manifest to guarantee reload:
touch /etc/kubernetes/manifests/kube-apiserver.yaml
Wait a few seconds.
7) Verify auditing is working
7.1 Check audit log file exists
ls -l /var/log/kubernetes/audit-logs.txt
7.2 Generate test activity
kubectl get namespaces
kubectl get configmaps -A
7.3 Confirm logs are written
tail -n 20 /var/log/kubernetes/audit-logs.txt
You should see audit entries.
