As you failed the issue of creating a container docker with nginx I do not know how you will upload the new applications in amazon, because for every language now there is an application, it is generated at compile time. I had configured nginx in case the application was accessed by the "/pt" address the user would be directed to the application in Portuguese, if the application had been accessed by any other path it would be directed to the "/en". I also created links with the flags for the user to change the path, but as I do not know how to do this targeting I did not commit this part of the code, I will wait for its definition.
