1. CORRECT TEXT





Task:

2. CORRECT TEXT





Context

A project that you are working on has a requirement for persistent data to be available.

Task

To facilitate this, perform the following tasks:

• Create a file on node sk8s-node-0 at /opt/KDSP00101/data/index.html with the content Acct=Finance

• Create a PersistentVolume named task-pv-volume using hostPath and allocate 1Gi to it, specifying that the volume is at /opt/KDSP00101/data on the cluster's node. The configuration should specify the access mode of ReadWriteOnce . It should define the StorageClass name exam for the PersistentVolume , which will be used to bind PersistentVolumeClaim requests to this PersistenetVolume.

• Create a PefsissentVolumeClaim named task-pv-claim that requests a volume of at least 100Mi and specifies an access mode of ReadWriteOnce

• Create a pod that uses the PersistentVolmeClaim as a volume with a label app: my-storage-app mounting the resulting volume to a mountPath /usr/share/nginx/html inside the pod

3. CORRECT TEXT





Context

It is always useful to look at the resources your applications are consuming in a cluster.

Task

• From the pods running in namespace cpu-stress, write the name only of the pod that is consuming the most CPU to file /opt/KDOBG030l/pod.txt, which has already been created.

4. CORRECT TEXT





Task:

The pod for the Deployment named nosql in the craytisn namespace fails to start because its container runs out of resources.

Update the nosol Deployment so that the Pod:

5. CORRECT TEXT





Context

A user has reported an aopticauon is unteachable due to a failing livenessProbe .

Task

Perform the following tasks:

• Find the broken pod and store its name and namespace to /opt/KDOB00401/broken.txt in the format:





The output file has already been created

• Store the associated error events to a file /opt/KDOB00401/error.txt, The output file has already been created. You will need to use the -o wide output specifier with your command

• Fix the issue.

6. CORRECT TEXT





Context

You have been tasked with scaling an existing deployment for availability, and creating a service to expose the deployment within your infrastructure.

Task

Start with the deployment named kdsn00101-deployment which has already been deployed to the namespace kdsn00101 . Edit it to:

• Add the func=webFrontEnd key/value label to the pod template metadata to identify the

pod for the service definition

• Have 4 replicas

Next, create ana deploy in namespace kdsn00l01 a service that accomplishes the following:

• Exposes the service on TCP port 8080

• is mapped to me pods defined by the specification of kdsn00l01-deployment

• Is of type NodePort

• Has a name of cherry

7. CORRECT TEXT





Given a container that writes a log file in format A and a container that converts log files from format A to format B, create a deployment that runs both containers such that the log files from the first container are converted by the second container, emitting logs in format B.

Task:

• Create a deployment named deployment-xyz in the default namespace, that:

• Includes a primary

lfccncf/busybox:1 container, named logger-dev

• includes a sidecar Ifccncf/fluentd:v0.12 container, named adapter-zen

• Mounts a shared volume /tmp/log on both containers, which does not persist when the pod is deleted

• Instructs the logger-dev container to run the command





which should output logs to /tmp/log/input.log in plain text format, with example values:





• The adapter-zen sidecar container should read /tmp/log/input.log and output the data to /tmp/log/output.* in Fluentd JSON format. Note that no knowledge of Fluentd is required to complete this task: all you will need to achieve this is to create the ConfigMap from the spec file provided at /opt/KDMC00102/fluentd-configma p.yaml , and mount that ConfigMap to /fluentd/etc in the adapter-zen sidecar container

8. CORRECT TEXT





Task

You are required to create a pod that requests a certain amount of CPU and memory, so it gets scheduled to-a node that has those resources available.

• Create a pod named nginx-resources in the pod-resources namespace that requests a minimum of 200m CPU and 1Gi memory for its container

• The pod should use the nginx image

• The pod-resources namespace has already been created

9. CORRECT TEXT





Context

As a Kubernetes application developer you will often find yourself needing to update a running application.

Task

Please complete the following:

• Update the app deployment in the kdpd00202 namespace with a maxSurge of 5% and a maxUnavailable of 2%

• Perform a rolling update of the web1 deployment, changing the Ifccncf/ngmx image version to 1.13

• Roll back the app deployment to the previous version

10. CORRECT TEXT





Task

A deployment is falling on the cluster due to an incorrect image being specified. Locate the deployment, and fix the problem.
