Docker - Is There a Way to Down Load a File?

With the add command though, you can add aurl. But guess what? You've already taken the hit of downloading the file that maybe you didn't want to down load every single time you're trying to build your image. And so in that case, it would be better to use a run statement with a curl or get to down load the file for you. Because doctor will only compute the check sum of the run command string, and not the result of whatever the file is.
