I have an Django app deployed to AWS using Elasticbeanstalk.
I implemented FCM(Firebase Cloud Messaging) relation to Django app. To access FCM feature from Django, it required Firebase Admin SDK installed to django. Firebase Admin SDK requires firebase's private key as json file accessed via env var GOOGLE_APPLICATION_CREDENTIALS.
On my local Mac Book env I set local path to private key json file to GOOGLE_APPLICATION_CREDENTIALS in .bash_profile.
How do I deploy the firebase's privatge key json file to somewhere safe on AWS(S3 maybe) and access from Django app deployed to AWS using Elasticbeanstalk.
