Missing file error when running a program in Alpine Docker container

Question

I have the following Dockerfile...

FROM gliderlabs/alpine

WORKDIR /go/src/app

ADD menu-api menu-api

ENTRYPOINT ["menu-api"]
CMD ["menu-api"]

If I build my go binary using $ GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build then build my Docker image $ docker build -t menu-api .

Then attempt to run my Docker image using $ docker run menu-api . I get the following error:

container_linux.go:262: starting container process caused "exec: \\"menu-api\\": executable file not found in $PATH" docker: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "exec: \\"menu-api\\": executable file not found in $PATH". ERRO[0000] error waiting for container: context canceled

Answer 1

As it turns out, I needed to do...

CMD ["./menu-api"]

Instead of...

CMD ["menu-api"]
