I want to use some env variables in my app, that runs on docker container. How can I get those environment variables in my code?
If I use dockerfile or docker-compose yaml, then how can I export it to read the values from the os on which it runs eventually and how can it be read in the code?
So for example, if I run my docker on AWS instances, I need the AWS keys from the instance to be used in my containerized app.
