docker-compose up未正确运行应用程序

我对docker很陌生。我有一个很棒的stack应用程序，并且已经为前端和后端配置了dockerfile，如下所示。当我运行docker-compose up时，它似乎完成了，但是当我进入localhost时，我看到的是这个而不是我的stack应用程序。

我不知道为什么，但很感谢你的帮助。

看起来你实际上并不需要Dockerfile作为前端，你肯定需要删除VOLUME声明，但我建议删除整个文件并使用“image：nginx”直接添加到您的docker-compose. yml中。
由于您没有构建前端应用程序，因此在运行docker-compose up之前，需要确保frontend/dist中有index.html。
另外，后端应用程序无法启动，因为它似乎试图运行node ./package.json。请检查package.json中start任务的定义。
进行这些更改后，您可以尝试重新运行您的docker-compose：

version: '3'
services:
    web:
        image: nginx
        ports:
            - "80:80"
        volumes:
        - "/Users/Phil/Documents/myapp/myapp-docker/frontend/dist:/usr/share/nginx/html"
    node:
        build: ./backend
        ports:
        - "3000:3000"

你指向了错误的文件夹。你的index.html文件在/dist/my-app，就像我在你上传的照片中看到的那样：https://postimg.cc/MntD9mFM .
修改您的Dockerfile和docker-compose以指向正确的文件夹。

构建版本1

停靠文件

FROM nginx
MAINTAINER Phil
#optional
RUN rm -rf /usr/share/nginx/html/*

VOLUME /Users/Phil/Documents/myapp/myapp-docker/frontend/dist/my-app:usr/share/nginx/html

EXPOSE 80

对接-组合：

version: '3'
services:
    web:
        build: ./frontend
        ports:
            - "80:80"
        links:
        - node
        volumes:
        - "/Users/Phil/Documents/myapp/myapp-docker/frontend/dist/my-app:/usr/share/nginx/html"
    node:
        build: ./backend
        ports:
        - "3000:3000"

构建版本2（更好）

您也可以忽略Dockerfile，因为Docker-compose已经指向您的卷，因此您的新Docker-compose将看起来像：

version: '3'
services:
    web:
        image: nginx
        ports:
            - "80:80"
        links:
        - node
        volumes:
        - "/Users/Phil/Documents/myapp/myapp-docker/frontend/dist/my-app:/usr/share/nginx/html"
    node:
        build: ./backend
        ports:
        - "3000:3000"
