💡 Hint

Common Mistakes

Using commands like cat or grep which do not encode data.

Forgetting the -n flag in echo which avoids adding a newline.

The base64 command encodes data to base64 format, which is required for Kubernetes Secrets.

medium

Complete the YAML snippet to define a Kubernetes Secret with base64 encoded data.

Kubernetes

apiVersion: v1
kind: Secret
metadata:
  name: mysecret
data:
  password: [1]

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

💡 Hint

Common Mistakes

Putting plain text instead of base64 encoded string.

Using incorrect base64 strings.

The value for password must be base64 encoded. 'cGFzc3dvcmQ=' is the base64 encoding of 'password'.

3fill in blank

hard

Fix the error in the command to decode a base64 encoded secret value.

Kubernetes

echo 'cGFzc3dvcmQ=' | [1]

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

💡 Hint

Common Mistakes

Using encoding flags instead of decoding.

Not using any flag, which defaults to encoding.

The -d flag tells base64 to decode the input back to plain text.

4fill in blank

hard

Fill both blanks to create a Kubernetes Secret YAML with a base64 encoded username and password.

Kubernetes

apiVersion: v1
kind: Secret
metadata:
  name: usersecret
data:
  username: [1]
  password: [2]

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

💡 Hint

Common Mistakes

Using plain text instead of base64 encoded strings.

Mixing up username and password values.

The username 'user' encoded in base64 is 'dXNlcg==', and the password 'password' encoded is 'cGFzc3dvcmQ='.

5fill in blank

hard

Fill all three blanks to create a Kubernetes Secret YAML with base64 encoded keys and values.

Kubernetes

apiVersion: v1
kind: Secret
metadata:
  name: appsecret
data:
  apiKey: [1]
  token: [2]
  env: [3]

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

💡 Hint

Common Mistakes

Putting plain text values instead of encoded strings.

Using incorrect base64 encodings.

'apikey123' encoded is 'YXBpS2V5MTIz', 'tokenValue' encoded is 'dG9rZW5WYWx1ZQ==', and 'production' encoded is 'cHJvZHVjdGlvbg=='.
