Question 50/86

You are developing a service that uses a custom configuration file called 'service.properties'. You want to use ConfigMaps to store and manage this file in a secure and efficient manner. The 'service-properties' file contains sensitive information such as database credentials and API keys.
How would you create a ConfigMap that securely stores the 'service-properties' file, ensuring that the file is accessible only to the service's container?

Correct Answer:

See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Create a Secret for Sensitive Data:
- Create a Secret

- Encode the 'service-properties' file: bash echo "your-database-username=your-database-username" > service-properties echo "your-database-password=your-database-password" >> service-properties echo 'Your-api-key=your-api-key" >> service.properties base64 -w 0 service.properties - Replace with the output from the base64 command. 2. Create the ConfigMap for the File:

3. Apply the Secret and ConfigMap: bash kubectl apply -f service-secrets-yaml kubectl apply -f service-config.yaml 4. Update the Deployment to use the ConfigMap and Secret

5. Apply the updated Deployment: bash kubectl apply -f my-service-deployment-yaml 6. Access the File in the Container. - Mount the ConfigMap and Secret: - The ConfigMap mounts the 'service.properties' file as a placeholder. - The Secret mounts the actual 'service.properties' file securely. - Access the File: - The container should access the 'service.properties' file from '/var/secrets/service/service.properties' This approach uses a Secret to store sensitive data and a ConfigMap to mount the file securely within the container. The container will have access to the 'service-properties' file, but the actual data is stored in the Secret, ensuring its confidentiality'.
