Linux Foundation CKA Certified Kubernetes Administrator (CKA) Program Exam Practice Test

Solution:

kubectl run busybox --image=busybox -it --rm --restart=Never --

/bin/sh -c 'echo hello world'

kubectl get po # You shouldn't see pod with the name "busybox"

kubectl get po -o=custom-columns="POD_NAME:.metadata.name,

POD_STATUS:.status.containerStatuses[].state"

kubect1 get pods -o=jsonpath='{range

items[*]}{.metadata.name}{"\t"}{.status.podIP}{"\n"}{end}'

kubectl get po -o=custom-columns="POD_NAME:.metadata.name,

POD_STATUS:.status.containerStatuses[].state"

kubectl run --generator=run-pod/v1 --image=nginx -- labels=env=prod nginx-prod --dry-run -o yaml > nginx-prodpod.yaml Now, edit nginx-prod-pod.yaml file and remove entries like “creationTimestamp: null” “dnsPolicy: ClusterFirst”

vim nginx-prod-pod.yaml

apiVersion: v1

kind: Pod

metadata:

labels:

env: prod

name: nginx-prod

spec:

containers:

- image: nginx

name: nginx-prod

restartPolicy: Always

# kubectl create -f nginx-prod-pod.yaml

kubectl run --generator=run-pod/v1 --image=nginx --

labels=env=dev nginx-dev --dry-run -o yaml > nginx-dev-pod.yaml

apiVersion: v1

kind: Pod

metadata:

labels:

env: dev

name: nginx-dev

spec:

containers:

- image: nginx

name: nginx-dev

restartPolicy: Always

# kubectl create -f nginx-prod-dev.yaml

Verify :

kubectl get po --show-labels

kubectl get po -l env=prod

kubectl get po -l env=dev

kubect1 get po nginx-dev -o

jsonpath='{.spec.containers[].image}{"\n"}'

Solution:

#yaml

apiVersion: v1

kind: Pod

metadata:

name: nginx-kusc00401

spec:

containers:

- name: nginx

image: nginx

imagePullPolicy: IfNotPresent

nodeSelector:

disk: spinning
