docker 多级构建在入口点找不到文件 [重复]

Question

这个问题在这里已经有了答案：

Go-compiled 二进制文件不会在 Ubuntu 主机上的高山 docker 容器中运行(6 个答案)

5 小时前关闭。

我的 docker 文件：

# syntax=docker/dockerfile:1

FROM golang:1.19-alpine AS build_con

COPY go.mod /
COPY go.sum /
COPY *.go /

RUN go mod download
RUN go get signservice
RUN go build -o /signservice_app /

FROM debian:bullseye-slim

RUN apt update && apt install -y \
pdftk \
imagemagick

RUN mkdir /signservice
RUN mkdir /signservice/resources
RUN mkdir /signservice/tmp

COPY --from=build_con signservice_app /signservice/signservice_app
COPY resources /signservice/resources/
COPY setperm.sh /signservice/
RUN chmod +x /signservice/setperm.sh
RUN chmod +x /signservice/signservice_app
RUN chmod 777 /signservice/
RUN chmod 777 /signservice/signservice_app
RUN /signservice/setperm.sh

ENTRYPOINT ["/signservice/signservice_app" ]

setperm.sh - 是 imagemagick 的配置

如果入口点：

ENTRYPOINT ["/signservice/signservice_app" ]

output：

signservicetest  | exec /signservice/signservice_app: no such file or directory
signservicetest exited with code 0
signservicetest exited with code 1

如果入口点：

ENTRYPOINT ["ls","-l", "/signservice/signservice_app" ]

output：

signservicetest  | -rwxrwxrwx 1 root root 11951301 Sep 27 12:15 /signservice/signservice_app

如果我在编译阶段应用程序工作后尝试设置入口点

它是什么？

Docker 版本 20.10.18，构建 b40c2f6 Ubuntu 20.04.5 LTS

图像在编译阶段是正确的
