Linux Foundation CKAD Certified Kubernetes Application Developer (CKAD) Program Exam Practice Test

Context

You are asked to prepare a Canary deployment for testing a new application release.

Task:

A Service named krill-Service in the goshark namespace points to 5 pod created by the Deployment named current-krill-deployment

1) Create an identical Deployment named canary-kill-deployment, in the same namespace.

2) Modify the Deployment so that:

-A maximum number of 10 pods run in the goshawk namespace.

-40% of the krill-service ‘s traffic goes to the canary-krill-deployment pod(s)

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

Task

Create a new deployment for running.nginx with the following parameters;

• Run the deployment in the kdpd00201 namespace. The namespace has already been created

• Name the deployment frontend and configure with 4 replicas

• Configure the pod with a container image of lfccncf/nginx:1.13.7

• Set an environment variable of NGINX__PORT=8080 and also expose that port for the container above

Task

A Deployment named backend-deployment in namespace staging runs a web application on port 8081.

Context

Your application’s namespace requires a specific service account to be used.

Task

Update the app-a deployment in the production namespace to run as the restrictedservice service account. The service account has already been created.

Task:

Create a Pod named nginx resources in the existing pod resources namespace.

Specify a single container using nginx:stable image.

Specify a resource request of 300m cpus and 1G1 of memory for the Pod’s container.

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

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

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
