Build docker images

[pwFoo]

Hi,

I tried to build a docker image / dockerfile. Build and start works fine.

FROM    golang:alpine

RUN     apk --update --no-cache add \
        gst-plugins-base-dev \
        gstreamer-dev \
        build-base \
        git

#RUN    go get github.com/pion/rtwatch

WORKDIR /rtwatch

ARG     REPO=https://github.com/pion/rtwatch.git
ARG     BRANCH=master

RUN     echo -e "GIT Repo: $REPO\nGIT Branch: $BRANCH"

RUN     git clone https://github.com/pion/rtwatch.git --progress --verbose --branch $BRANCH /rtwatch

RUN     sed -i 's#ws://#wss://#g' main.go

RUN     go install


FROM    alpine:latest

RUN     apk --update --no-cache add \
        gst-plugins-good \ 
        gst-plugins-ugly \
        gst-plugins-bad \
        gstreamer 

COPY    --from=0 /go/bin/rtwatch /usr/local/bin/rtwatch

ENTRYpoint      [ "/usr/local/bin/rtwatch" ]
CMD             [ "-container-path", "/data/video.mp4" ]

• Video file need to be mapped as volume.
• For tests ws:// was replaced by wss://
