Building the following Dockerfile on GitLab CI using Kaniko, result in the error error pushing image: failed to push to destination eu.gcr.io/stritzke-enterprises/eliah-speech-server:latest: Get https://eu.gcr.io/...: exit status 1
If I remove the first FROM, RUN and COPY --from statements from the Dockerfile, the Docker Image is built and pushed as expected. If I execute the Kaniko build using Docker on my local machine everything works as expected. I execute other Kaniko builds and pushed on the same GitLab CI runner with the same GCE Service Account credentials.
What is going wrong with the GitLab CI based Kaniko build?
FROM alpine:latest as alpine
RUN apk add -U --no-cache ca-certificates
FROM scratch
COPY --from=alpine /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
COPY binaries/speech-server /speech-server
EXPOSE 8080
ENTRYPOINT ["/speech-server"]

As tdensmore pointed out this was most likely an authentication issue.
So for everyone who has come here, the following Dockerfile and Kaniko call work just fine.
FROM ubuntu:latest as ubuntu
RUN echo "Foo" > /foo.txt
FROM ubuntu:latest
COPY --from=ubuntu /foo.txt /
CMD ["/bin/cat", "/foo.txt"]
The Dockerfile can be built by running
docker run -v $(pwd):/workspace gcr.io/kaniko-project/executor:latest --context /workspace --no-push
