Bettercap: Docker Build not passing with Alpine version

[khast3x]

Description of the bug or feature request

The current Dockerfile tries to build from Alpine but does not finish.

Perhaps you should add the directory containing `libnetfilter_queue.pc'

The current travis build uses a debian-based dockerfile, thus installing the libnetfilter_queue correctly.
The provided example is by doing a git pull of the bettercap repo. This was done on the play-with-docker.com docker hosts.

Imho, we should either find a way to build the missing lib for Alpine or revert to a Debian based Dockerfile.

Or just remove Docker because I'm super tired of it ...

[evilsocket]

To be honest I don't know Docker enough to fix this, hoping that someone can send a PR ...

It seams to be related to Alpine Linux, not Docker.
I will be able to test it tomorrow.
But trying to simplify it might be a good start.

It could look like this:

FROM golang:alpine

RUN apk add --update ca-certificates iproute2 libpcap-dev  # bash -do you really need "bash" ? Alpine uses "ash"
RUN apk add --no-cache --update bash iptables wireless-tools build-base libpcap-dev git python py-six

# Copy the local package files to the container's workspace.
ADD . /go/src/github.com/github.com/bettercap/bettercap

Install any go dependencies  ?
# RUN  go get github.com/...
RUN  go install github.com/bettercap/bettercap

EXPOSE 80 443 53 5300 8080 8081 8082 8083 8000
ENTRYPOINT /go/bin/bettercap
