docker build with given Dockerfile fails.

[ricky-charlet]

Describe the bug
Cannot build a docker image with given Dockerfile in docker/bio-rd/Dockerfile

Steps to Reproduce
cd docker/bio-rd
docker build --tag 'rickys' .

(attempted workaround)
cp ../../go.mod .
docker build --tag 'rickys' .

(2nd attempted workaround)
cd ../.. (top dir of bio-rd)
docker build --tag 'rickys' docker/bio-rd/

Expected behavior
successfully build a docker image which contains bio-rd binary

Additional FYI.

If I edit the Dockerfile to look like this:

FROM golang as builder
ADD . /go/bio-rd
WORKDIR /go/bio-rd/cmd/bio-rd
# RUN GOOS=linux go build -o /go/bin/bio-rd
RUN bash

# FROM debian:stable
# WORKDIR /app
# COPY --from=builder /go/bin/bio-rd .
# CMD /app/bio-rd --config.file=/config/bio-rd.yml ${CMD_ARGS}
# RUN apt update && \
#    apt install -y libcap2-bin && \
#    setcap cap_net_bind_service+eip /app/bio-rd && \
#    useradd --system bio-rd
# USER bio-rd
# VOLUME /config
# EXPOSE 179
# EXPOSE 5566
# EXPOSE 55667

Then run the container and exec a bash shell into it, and from within that running container, attempt the same GOOS=linux go build -o /go/bin/bio-rd command by hand, I get these errors:

none of go get go mod tidy or individual calls to stuff like go get github.com/bio-routing/bio-rd/cmd/bio-rd/config Seem to help.
