質問 # 232 
Context
Developers occasionally need to submit pods that run periodically.
Task
Follow the steps below to create a pod that will start at a predetermined time and]which runs to completion only once each time it is started:
* Create a YAML formatted Kubernetes manifest /opt/KDPD00301/periodic.yaml that runs the following shell command: date in a single busybox container. The command should run every minute and must complete within 22 seconds or be terminated oy Kubernetes. The Cronjob namp and container name should both be hello
* Create the resource in the above manifest and verify that the job executes successfully at least once See the solution below.

You must connect to the correct host . Failure to do so may result in a zero score.
[candidate@base] $ ssh ckad00032
The Pod for the Deployment named nosql in the haddock namespace fails to start because its Container runs out of resources.
Update the nosql Deployment so that the Container :
* requests 128Mi of memory
* limits the memory to half the maximum memory constraint set for the haddock namespace See the Explanation below for complete solution.
正解：
解説：
Goal: fix nosql Deployment in haddock so the container stops OOM'ing by setting:
* memory request = 128Mi
* memory limit = half of the namespace's maximum memory constraint
You must do this on the correct host.
0) Connect to the correct host
ssh ckad00032
1) Confirm the failing Deployment / Pods
kubectl -n haddock get deploy nosql
kubectl -n haddock get pods -l app=nosql 2>/dev/null || kubectl -n haddock get pods If pods are crashing, check why (you'll likely see OOMKilled):
kubectl -n haddock describe pod <pod-name>
2) Find the maximum memory constraint set for the haddock namespace
In CKAD labs, this is commonly enforced by a LimitRange (max memory per container). Sometimes it can also be a ResourceQuota.
2A) Check LimitRange (most likely)
kubectl -n haddock get limitrange
kubectl -n haddock get limitrange -o yaml
Extract the max memory value quickly:
MAX_MEM=$(kubectl -n haddock get limitrange -o jsonpath='{.items[0].spec.limits[0].max.memory}') echo "Namespace max memory constraint: $MAX_MEM"
2B) If no LimitRange exists, check ResourceQuota
kubectl -n haddock get resourcequota
kubectl -n haddock describe resourcequota
If quota is used, you're looking for something like limits.memory (but the question wording "maximum memory constraint" usually points to LimitRange max.memory).
3) Compute "half of the max memory constraint"
Run this small snippet to compute HALF in Mi (handles Mi and Gi):
HALF_MEM=$(python3 - <<'PY'
import os, re
q = os.environ.get("MAX_MEM","").strip()
m = re.fullmatch(r"(\d+)(Mi|Gi)", q)
if not m:
raise SystemExit(f"Cannot parse MAX_MEM='{q}'. Expected like 512Mi or 1Gi.") val = int(m.group(1)) unit = m.group(2)
# convert to Mi
mi = val if unit == "Mi" else val * 1024
half_mi = mi // 2
print(f"{half_mi}Mi")
PY
)
echo "Half of max: $HALF_MEM"
Example: if MAX_MEM=512Mi # HALF_MEM=256Mi
Example: if MAX_MEM=1Gi # HALF_MEM=512Mi
4) Update the nosql Deployment (DO NOT delete it)
First, get the container name (Deployment may have a custom container name):
kubectl -n haddock get deploy nosql -o jsonpath='{.spec.template.spec.containers[*].name}{"\n"}' Now set resources (this updates the Deployment in-place):
kubectl -n haddock set resources deploy nosql \
--requests=memory=128Mi \
--limits=memory=$HALF_MEM
5) Ensure the update rolls out successfully
kubectl -n haddock rollout status deploy nosql
6) Verify the pod has the right requests/limits
kubectl -n haddock get deploy nosql -o jsonpath='{.spec.template.spec.containers[0].resources}{"\n"}' kubectl -n haddock get pods Pick the new pod and confirm:
kubectl -n haddock describe pod <new-pod-name> | sed -n '/Requests:/,/Limits:/p' You should see:
* Requests: memory 128Mi
* Limits: memory <HALF_MEM>
If rollout fails (common cause)
If you accidentally set a limit above the namespace max, pods won't start. Check events:
kubectl -n haddock describe deploy nosql
kubectl -n haddock get events --sort-by=.lastTimestamp | tail -n 20
質問 # 234
You have a Deployment named that runs 3 replicas of a Wordpress container. You need to implement a rolling update strategy that allows for a maximum or two pods to be unavailable at any given time during the update process. Additionally, you want to ensure that the update process is triggered automatically whenever a new image is pushed to the Docker Hub repository 'wordpress/wordpress:latest'.
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. IJPdate the Deployment YAMLI
- Update the 'replicas to 2.
- Define 'maxunavailable: 2 and 'maxSurge: O' in the 'strategy.rollingupdate' section to control the rolling update process.
- Configure a 'strategy-type' to 'RollinglJpdate' to trigger a rolling update when the deployment is updated.
- Add a 'spec-template-spec-imagePullPolicy: Always" to ensure that the new image is pulled even if it exists in the pod's local cache.
2. Create the Deployment - Apply the updated YAML file using 'kubectl apply -f wordpress-deploymentyamr 3. Verify the Deployment: - Check the status of the deployment using 'kubectl get deployments wordpress-deployment to confirm the rollout and updated replica count. 4. Trigger the Automatic Update: - Push a new image to the 'wordpress/wordpress:latest' Docker Hub repository. 5. Monitor the Deployment: - Use 'kubectl get pods -l app=wordpress' to monitor the pod updates during the rolling update process. You will observe that two pods are terminated at a time, while two new pods with the updated image are created. 6. Check for Successful Update: - Once the deployment is complete, use 'kubectl describe deployment wordpress-deployment' to see that the 'updatedReplicas' field matches the 'replicas' field, indicating a successful update.
質問 # 235
You are building a microservice called 'order-service' that handles order processing. You need to configure a Securitycontext for the 'order-service' container tnat ensures it can access the network to communicate With other services and access specific hostPath volumes, but it should not have root privileges.
正解：
解説：
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Define the Securitycontext:
- Create a 'securityContext' section within the 'spec.template.spec.containers' block for your 'order-service' container.
- Set 'runAslJser' to a non-root IJID (e.g., 1001) to prevent running as the root user-
- Set 'allowPrivilegeEscalation' to 'false' to prevent the container from escalating its privileges.
- Set 'capabilities' to an empty array (so') to disable any additional capabilities.
2. Mount HostPath Volumes: - Define 'volumeMountS for the required hostPath volumes. - Specify the mount path within the container C Idata' and 'Iconfig' in this example) and the volume name. - Define corresponding 'volumes with the 'hostPath' type, specifying the source path on the host and the volume name. 3. Create the Deployment: - Apply the Deployment YAML file using 'kubectl apply -f order-service-deployment-yaml' - The 'securitycontext' restricts the container's access to the host system's resources and prevents privilege escalation. - Setting 'runAsUserS to a non-root I-IID ensures that tne container runs as a non-root user - 'allowPriviIegeEscalation' prevents the container from elevating its privileges, even if it has the necessary capabilities. - The 'capabilities' section allows you to explicitly detine WhiCh capabilities the container snould nave. In this case, an empty array disables all additional capabilities, restricting the container's potential actions. - The 'volumeMounts' define how hostPath volumes are mounted within the container, providing access to specific directories on the host system. This configuration ensures that the 'order-service' container can access specific hostPath volumes and the network for communication with other services without running as root and without any additional capabilities, enhancing security.
