Set Go Glide in Docker - docker

Question

I am building an app with Go and Glide in docker. I also have to use reflex to trigger the compiling automatically.
I can not figure out how to make Glide work out with docker.
Dockerfile
FROM golang:1.8.1-alpine
ENV GOBINARIES /go/bin
ENV BUILDPATH /code
ENV REFLEXURL=http://s3.amazonaws.com/wbm-raff/bin/reflex1.8a

WORKDIR $GOBINARIES
RUN rm -rf /var/cache/apk/*
RUN wget -q "$REFLEXURL" -O reflex
RUN chmod +x /go/bin/reflex
ENV TOOLS /go/_tools
RUN mkdir -p $BUILDPATH
ENV PORT 5000
EXPOSE $PORT
RUN mkdir -p $TOOLS
ADD build.sh $TOOLS
ADD reflex.conf $TOOLS
RUN chown root $TOOLS/build.sh
RUN chmod +x $TOOLS/build.sh
WORKDIR $BUILDPATH
CMD ["reflex","-c","/go/_tools/reflex.conf"]
build.sh
set -e
echo "[build.sh:building binary]"
cd $BUILDPATH
glide install -s -v
go build -o /servicebin && rm -rf /tmp/*
echo "[build.sh:launching binary]"
/servicebin
reflex.conf

}
func main() {
log.SetOutput(os.Stdout)
port := ":" + os.Getenv("PORT")
http.HandleFunc("/", hello)
log.Printf("\n Application is listening on %v\n", port)
http.ListenAndServe(port, nil)
}

Actually, I do not need to install Glide in the container! Just reflect the vendor folder in host machine to $GOPATH/src in docker-compose.yml. Then the compile will be ok.
