at the moment I try to figure out a good setup for my application in amazon ecs. 

My application needs a config file. Now I want to have a container to hold my config file so when I want to change something I don't need to redeploy my application.

I can't find any best practice method for this. What I found out is that the ecs tasks just make a `docker run` and you can't make a `docker create`.

Does anyone have an idea how I can manage my config files for my applications?
