Docker error: entrypoint permission denied

Docker error: entrypoint permission denied

我正在尝试构建一个 docker 图像,其中入口点可以 运行 而不会出现错误:

docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/app\": permission denied": unknown.

我的 OS: Windows 10

Dockerfile 内容:

ARG GO_VERSION=1.11
FROM golang:${GO_VERSION}-alpine AS builder
RUN mkdir /user && \
    echo 'nobody:x:65534:65534:nobody:/:' > /user/passwd && \
    echo 'nobody:x:65534:' > /user/group
RUN apk add --no-cache ca-certificates
ENV CGO_ENABLED=0 GOFLAGS=-mod=vendor
WORKDIR $GOPATH/src/XXXXmyrepoXXXX
COPY ./ ./
RUN go build \
    -installsuffix 'static' \
    -o /app .


FROM scratch AS final
COPY --from=builder /user/group /user/passwd /etc/
COPY --from=builder /etc/ssl/certs/ca-certificates.crt /etc/ssl/certs/
COPY --from=builder /app /app
EXPOSE 8080
USER nobody:nobody
ENTRYPOINT ["/app"]

我应该如何更改 Dockerfile,它应该像这里一样工作 https://medium.com/@pierreprinetti/the-go-1-11-dockerfile-a3218319d191?字面上没有任何变化。

错误是我没有去构建正确的路径。
