Hi, this is Mizzlr. I have updated your docker file, to make it cleaner and build to a smaller image size. The modified docker file builds to an image of size 537 MB, while the original docker file resulted in an image of size 640 MB. I have built and tested the modified docker file, and works awesome. Please accept my proposal for docker file change.
i'm not sure if i'm on an old docker version or not, but i had to fix this line to get it to build. feel free to disregard if it's just my docker being old
