Question about any idea to reduce the docker image size

[jiangyh91]

Hi, thanks for maintianing this repo up to date.
The docker image size on my server takes 1.29GB, which I am feeling is relatively too big compare with the image's feature.
I am not a expert user of docker, feel free to fix me if I say anything wrong.
From the Dockerfile, I can see few things we can do to reduce the image size.

1. Switched to alpine:latest for a smaller base image.

FROM alpine:latest or maybe any python ready image?

2. Combined unnecessary RUN instructions to reduce the number of layers.

RUN apt-get -y install ${PYTHON}-pip && \ apt-get -y install ${PYTHON}-selenium && \ apt-get -y install ${PYTHON}-pyotp && \ apt-get -y install curl wget etc.

What do you think about above ideas? Thank you.

Hi, thanks for your comment!
The image size is largely due to the chromium and Chrome driver needed by the python code to emulate a real browser, I'm not sure it could be reduced or if alpine based images can be used, if you manage to try I'd be happy to accept PRs!
