Variable encryption for secrets in Apache Airflow - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable encryption for Airflow variables.

Apache Airflow

from airflow.models import Variable

secret_value = Variable.get('[1]', deserialize_json=True)

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

Bmy_variable

Cconfig_value

💡 Hint

Common Mistakes

Using a variable name that does not exist in Airflow variables.

Not setting deserialize_json=True when the secret is stored as JSON.

The variable name my_secret is used to retrieve the encrypted secret stored in Airflow variables.

medium

Complete the code to set an encrypted variable in Airflow using the CLI.

Apache Airflow

airflow variables [1] my_secret_key my_secret_value

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

Blist

Cget

Dset

💡 Hint

Common Mistakes

Using 'get' instead of 'set' to create a variable.

Trying to use 'list' or 'delete' commands to set a variable.

The set command is used to create or update a variable in Airflow, which can be encrypted if encryption is enabled.

3fill in blank

hard

Fix the error in the code to correctly retrieve an encrypted variable as a string.

Apache Airflow

secret = Variable.get('[1]', deserialize_json=[2])

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

AFalse

BNone

CTrue

D0

💡 Hint

Common Mistakes

Setting deserialize_json to True when the variable is not JSON.

Passing None or 0 instead of a boolean value.

When retrieving a secret stored as a plain string, deserialize_json should be set to False to avoid errors.

4fill in blank

hard

Fill both blanks to create a variable dictionary comprehension filtering secrets with length greater than 5.

Apache Airflow

secrets = {key: Variable.get(key) for key in Variable.get('[1]') if len(Variable.get(key)) [2] 5}

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

B>

C<

Dkeys_list

💡 Hint

Common Mistakes

Using the wrong variable name for keys.

Using less than operator instead of greater than.

all_keys is used to get all variable keys, and the condition > filters secrets longer than 5 characters.

5fill in blank

hard

Fill all three blanks to create a dictionary of uppercase keys and their decrypted values where values are not empty.

Apache Airflow

decrypted = { [1]: Variable.get([2]) for [3] in Variable.get('all_keys') if Variable.get([3]) != '' }

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

Akey.upper()

Bkey

Dkeys

💡 Hint

Common Mistakes

Using different variable names inconsistently.

Not converting keys to uppercase.

The dictionary uses key.upper() for keys, retrieves values with Variable.get(key), and iterates with key.
