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)

Task:

Create a Deployment named expose in the existing ckad00014 namespace running 6 replicas of a Pod. Specify a single container using the ifccncf/nginx: 1.13.7 image

Add an environment variable named NGINX_PORT with the value 8001 to the container then expose port 8001

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

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.

Task:

Modify the existing Deployment named broker-deployment running in namespace quetzal so that its containers.

1) Run with user ID 30000 and

2) Privilege escalation is forbidden

The broker-deployment is manifest file can be found at:

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

Context

Anytime a team needs to run a container on Kubernetes they will need to define a pod within which to run the container.

Task

Please complete the following:

• Create a YAML formatted pod manifest

/opt/KDPD00101/podl.yml to create a pod named app1 that runs a container named app1cont using image Ifccncf/arg-output

with these command line arguments: -lines 56 -F

• Create the pod with the kubect1 command using the YAML file created in the previous step

• When the pod is running display summary data about the pod in JSON format using the kubect1 command and redirect the output to a file named /opt/KDPD00101/out1.json

• All of the files you need to work with have been created, empty, for your convenience

Task:

1) Create a secret named app-secret in the default namespace containing the following single key-value pair:

Key3: value1

2) Create a Pod named ngnix secret in the default namespace.Specify a single container using the nginx:stable image.

Add an environment variable named BEST_VARIABLE consuming the value of the secret key3.

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.
