Docker image build error: shell script file is copied in the workdir but it says the file is not found

Question

我正在尝试使用 alpine 对遗留 java 项目进行 dockerize。 我的机器在 Windows 10 上运行，我正在使用适用于 Windows 的 Docker Desktop。

这是我的

Dockerfile

：

FROM openjdk:8u171-jdk-alpine
RUN apk -U add tini
WORKDIR /mnt
COPY ./ ./
RUN chmod +x ./posix-compile.sh && ls && sh ./posix-compile.sh
ADD https://github.com/ufoscout/docker-compose-wait/releases/download/2.6.0/wait /wait
RUN chmod +x /wait

EXPOSE 8484
ENTRYPOINT ["tini", "--"]
CMD /wait && sh ./posix-launch.sh

这是

docker-compose.yml

version: '3'
services:
  test_server:
    network_mode: "host"
    build: .
    depends_on:
      - db
    environment:
      WAIT_HOSTS: localhost:3306
    
  db:
    network_mode: "host"
    image: mysql:5.6
    environment:
      MYSQL_ALLOW_EMPTY_PASSWORD: "yes"
      MYSQL_DATABASE: "test"
      MYSQL_USER: "root"
      MYSQL_PASSWORD: ""
    volumes:
      - ./sql:/docker-entrypoint-initdb.d

还有臭名昭著的

posix-compile.sh

#!/bin/bash

src=src
dist=dist

cores=$(echo cores/*)
cores=${cores// /:}

mkdir -p $dist
javac -d $dist -cp $cores $(find $src -name "*.java")

我尝试通过运行此命令来构建图像：

docker build --progress=plain --no-cache -t image_name:test_server .

这是我项目根目录的快照，以帮助理解项目结构。

ls

的结果显示，

posic-compile.sh

在那里，我不明白为什么或怎么说找不到这个文件。

我以为可能是权限问题，这就是为什么我在

Dockerfile

的第5行的开头添加，

chmod +x ./posix-compile.sh

，但是它没有改变任何东西。

我尝试通过指定

/mnt/posix-compile.sh

使用绝对路径，它也没有用。
