 2. Configure your environment variables in `client_app/Dockerfile`. Replace the property values with the values the were outputted from the backend Terraform deployment in your terminal. You will leave `APP_URI` as a placeholder for now because the URI will be the Cloudfront URL output from your Front End Terraform deployment.

-  Note: The ```COGNITO_CLIENT_SECRET``` is a secret value that can be retrieved from the AWS Console. Go to the [Amazon Cognito page](https://console.aws.amazon.com/cognito/home) in the AWS console, then select the created user pool. Under App integration, select App client settings. Then, select Show Details and copy the value of the App client secret.
