Could update a Docker image

[WenJing]

Thanks so much for your fork, the 'following' feature you added is super helpful! I'm really keen to set it up for myself, but I've run into a bunch of issues trying to get it deployed. Any chance you could update a Docker image? That would be awesome and super appreciated!

I apologize for asking a foolish question. I realized that I can complete this operation myself using a Dockerfile.
