title: How to store GOOGLE_APPLICATION_CREDENTIALS in an AWS ECS environment on Fargate?
body: <p>We have an API app that uses Firebase Admin to send messages to devices.
  Earlier, we used to specify the service account key using environment variable like GOOGLE_APPLICATION_CREDENTIALS=&quot;path_to_file.json&quot;.
  But now, since we are shifting to AWS Elastic Container Service on Fargate, I am unable to figure out how to put this file in the container for AWS ECS.</p>
  <p>Any advice highly appreciated.</p>
  <p>Thanks</p>
