Docker redo

Closes #56

[gaul]

Do we need to remove this? Ideally casual users would not need to build the docker image.

[SuperSandro2000]

I can't push to it. I could set it up in my docker image repo if you like.

Hi @SuperSandro2000,

I get following exception with your docker:

Step 6/11 : RUN go build -ldflags='-extldflags "-static" -s -w' -o /go/bin/compy

Any clue?

[SuperSandro2000]

@lolobosse no clue, builds for me.

@lolobosse I got the same problem, looks like something to do with Alpine's glibc maybe? Switching to the non-Alpine Go image (i.e. 1.16 instead of 1.16-alpine) fixed it for me. Updated PR incoming.
