It is basically problem when I run in docker container. This is sample
program.

When I run localhost, it workes well. when I tries to run docker container,
it didnt work. I can give my dockerfile here.
FROM golang:1.9-alpine as dev
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
RUN apk add --no-cache --repository
http://dl-3.alpinelinux.org/alpine/edge/community upx
WORKDIR /go/src/project
COPY ./main.go /go/src/project
RUN go build -o /bin/project
FROM scratch
COPY --from=dev /bin/project /bin/project
ENTRYPOINT ["/bin/project"]

I have another problem when I run in Docker with CPU profile.
In this case where to report the issues?
