Docker is one of the tools that was concocted (by brilliant people!) after I began programming professionally. From my understanding, Docker allows you to containerize your applications so they function properly anywhere you (so to say) "place those containers". Now, does if I'm working with say Django or Flask, and things behave differently on an AWS server than they do on your local machine, for example — relative paths for file uploads work on localhost, but mess up on AWS. Also file permissions are irritating to work with on AWS, but never an issue on localhost (on a Mac). In such a scenario, is Docker for these issues? I imagine I use Docker, make a "container" and setup everything properly in that, and then just move it to AWS when I'm deploying?
