Practice - 5 Tasks

1fill in blank

easy

Complete the code to install a Helm chart named 'myapp'.

Kubernetes

helm [1] install myapp ./mychart

Drag options to blanks, or click blank then click option'

Bcreate

Cdelete

Dinstall

💡 Hint

Common Mistakes

Using 'create' instead of 'install' will not deploy the app.

Using 'delete' removes apps, not installs them.

The install command is used to deploy a Helm chart to Kubernetes.

2fill in blank

medium

Complete the code to upgrade an existing Helm release named 'myapp'.

Kubernetes

helm [1] upgrade myapp ./mychart

Drag options to blanks, or click blank then click option'

Ainstall

Bupgrade

Crollback

Dstatus

Attempts:

💡 Hint

Common Mistakes

Using 'install' again may cause errors if release exists.

Using 'rollback' reverts changes, not upgrades.

The upgrade command updates an existing Helm release with new chart changes.

3fill in blank

hard

Fix the error in the Helm command to list all releases.

Kubernetes

helm [1] --all-namespaces

Drag options to blanks, or click blank then click option'

Alist

Bshow

Cget

Dstatus

Attempts:

💡 Hint

Common Mistakes

Using 'show' or 'get' does not list releases.

Using 'status' shows info for one release only.

The list command shows all Helm releases, and --all-namespaces includes all namespaces.

4fill in blank

hard

Fill both blanks to create a Helm values override file and apply it during install.

Kubernetes

helm install myapp ./mychart -f [1] --set [2]

Drag options to blanks, or click blank then click option'

Acustom-values.yaml

BreplicaCount=3

Cimage.tag=latest

Ddefault-values.yaml

Attempts:

3 left

💡 Hint

Common Mistakes

Using default-values.yaml may not reflect custom settings.

Setting image.tag=latest is valid but not the expected answer here.

The -f flag loads a values file like custom-values.yaml. The --set flag overrides specific values like replicaCount=3.

5fill in blank

hard

Fill all three blanks to define a Helm template snippet that creates a ConfigMap with a key and value.

Kubernetes

apiVersion: v1
kind: ConfigMap
metadata:
  name: [1]
data:
  [2]: [3]

Drag options to blanks, or click blank then click option'

Amy-config

BconfigKey

C"configValue"

Ddefault-config

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting quotes around the value causes YAML errors.

Using default-config as name is valid but not the expected answer.

The ConfigMap name is my-config. The data key is configKey with value "configValue" (quotes needed for string).
