Solution (Step by Step) :
1. Create a Kubernetes Secret:
- Create a YAML file, for example, 'database-secret.yamr , with the following content:

- Replace ". ". ". and with the actual values, Base64 encoded. You can use the 'base64' command to encode the values: bash echo "your _ username" | base64 echo 'Your_password" | base64 echo "your _ host" | base64 echo "your _ port" | base64 2. Apply the Secret: - Apply the secret to your Kubernetes cluster: bash kubectl apply -f database-secret.yaml 3. Modify the Deployment: - Modify your Deployment YAML file to mount the secret as a file:

4. Apply the Updated Deployment: - Apply the updated Deployment YAML file using: bash kubectl apply -f my-microservice-deployment.yaml 5. Accessing Credentials: - The application container can now access the environment variables from the secret using 'process-env-DATABASE USER , 'process.env.DATABASE_PASSWORD', etc. Additionally, the secret data is mounted as a file at '/var/secrets/database'.
