I have a docker-based Flask app that I have been developing and it's nearing completion. I am currently moving to hosting it on AWS. The app allows users to generate various forms of content (usually image files) that are saved into a UGC folder within the /static folder of the app in my dev environment. This temporary solution worked fine in dev but it isn't going to suffice when ported to live as the static/ugc folder will be destroyed with each image update.
I therefore need an alternative solution and have been investigating EFS. Does anybody have experience with this service? Or in hosting persistent static files outside of a Docker app container in general and could advise?
You should probably look at using the S3 object storage service, via the boto3 python client.
There's also a flask extension, Flask-S3 which allows you to host general assets on S3 automatically. You'd probably need to code the logic for user-uploaded content yourself.
