在Alpine Docker容器中运行程序时丢失文件错误

Question

我有以下Dockerfile ......

FROM gliderlabs/alpine

WORKDIR /go/src/app

ADD menu-api menu-api

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

如果我使用$ GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build构建我的go二进制文件，那么构建我的Docker镜像$ docker build -t menu-api .

然后尝试使用$ docker run menu-api运行我的Docker镜像。我收到以下错误：

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

事实证明，我需要做......

CMD ["./menu-api"]

而不是......

CMD ["menu-api"]
