Docker image not built

docker build .

gives

Step 5/10 : RUN go get -d -v

Changing Dockerfile to

RUN go get -d -v
RUN go test -v
RUN CGO_ENABLED=0 GOOS=linux go install -a -v

FROM scratch
COPY --from=0 /go/bin/telescope-control-system /
CMD ["/telescope-control-system"]

and building with

docker build --build-arg GITHUB_USER=$GITHUB_USER --build-arg GITHUB_PASS=$GITHUB_PASS .

with shell variables GITHUB_USER and GITHUB_PASS set, downlods everything from github:

but still fails with

This Dockerfile

FROM golang:1

# Copy Source code...

RUN ./build-deps
RUN go install

CMD ["telescope-control-system"]

(slightly adapted from https://github.com/ccatp/demos/blob/master/2020-08-acu_sim-housekeeping/tcs/Dockerfile) works:

> docker build --build-arg GITHUB_USER=$GITHUB_USER --build-arg GITHUB_PASS=$GITHUB_PASS .

How do I use the image that is built by the github workflow? Most probably with

docker pull gcr.io/${{ secrets.GCLOUD_PROJECT_ID }}/telescope-control-system:latest

but what is secrets.GCLOUD_PROJECT_ID?

[nolta]

I can also publish to github packages: https://github.com/ccatp/telescope-control-system/packages/447887

Does that work?

Pulling the image from github works; building the image locally still fails with

Step 9/14 : RUN go get -d -v

github_ssh_key_ed25519 contains my private key for github and was made accessible for docker, so I think that should work, but it doesn't... Anyway, I can make it work with

ARG GITHUB_USER
ARG GITHUB_PASS
RUN echo "machine github.com\n\tlogin $GITHUB_USER\n\tpassword $GITHUB_PASS" >> ~/.netrc

instead of

ADD github_ssh_key_ed25519 /root/.ssh/id_ed25519
RUN chmod 700 /root/.ssh/id_ed25519
RUN echo "Host github.com\n\tStrictHostKeyChecking no\n" >> /root/.ssh/config
RUN git config --global url.ssh://[email protected]/ccatp/.insteadOf https://github.com/ccatp/

in the Dockerfile, so I have a work-around, and since this is not my turf in the first place, we can leave it as it is.
