Node.js Docker compose up已退出，代码为1，但Docker compose生成成功

当尝试docker compose up时，我从前端和后端收到错误，它们以代码1退出。docker ps显示postgres容器仍在运行，但前端和后端仍在退出。使用npm start，没有错误。我不知道这是否有帮助，但我的文件没有从src文件夹复制到/usr/src/app/所以我的docker compose或DockerFile可能有错误

Docker ps显示：

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

这就是后端Dockerfile的外观

FROM node:current-alpine

RUN mkdir -p /usr/src/app

WORKDIR /usr/src/app/

COPY package*.json /usr/src/app/

RUN npm install

COPY . /usr/src/app/

EXPOSE 3000

ENV NODE_ENV=production

CMD ["npm", "start"]

和输出错误：

任何帮助都将不胜感激，谢谢

更新的nginx.conf:

server {
    listen 80;
    server_name example.org;

    location / {
        root /var/www/html/;
        index index.html;
        autoindex on;
    }

    location /frontend {
        proxy_pass http://example.org:8080;
        try_files $uri /public/index.html;
    }

    location /backend {
        proxy_pass http://example.org:3000;
    }

    location /db {
        proxy_pass http://example.org:5432;
    }
}

更改时出现新错误。gitignore：

设置似乎非常复杂。我给你的建议是：使用certbot作为自己的docker容器，尽量减少复杂的开销

#docker-compose.yml

version: '3'

services:
  frontend:
    build: ./frontend
    volumes:
      - ./data/nginx:/etc/nginx/conf.d
      # no source-code of the frontend via volumes - 
      # only a nginx-image with your source. 
      # nginx-conf as volume is valid.
    ports:
      - 8080:80
    depends_on:
      - backend
  backend:
    build: ./backend
    # dont put your source as volume in, 
    # your docker-image should contains the whole code
    # and no certbot magic here
    ports:
      - 3000:3000
    depends_on:
      - db
  db:
    image: postgres:latest
    restart: always
    environment:
      POSTGRES_USER: example
      POSTGRES_PASSWORD: example1234
      POSTGRES_DB: example
    ports:
      - 5432:5432

这是非常干净，易于阅读。现在，您应该在主机（）上设置反向代理。将已发布的端口配置到nginx反向代理中（例如，前端的本地主机：8080）

---

之后，您可以安装certbot并获取您的lets加密证书。certbot应该自动发现您的nginx端点，并可以自动续订您的证书。

感谢您的快速回答，但无论您建议添加什么，我仍然会收到相同的错误。在运行docker compose up之前，如果证书已经存在，会有区别吗？不会。你能为我们发布你的app.conf吗？似乎有错误（它试图对不存在的

/etc/letsencrypt/options ssl nginx.conf

执行某些操作）。在

数据/certbot/conf

中是否有

选项ssl nginx.conf

？是的，它存在。确定吗？它不在您的目录结构中。对不起，它存在于我的服务器上。我假设当我运行certbot时，它创建了目录结构。它存在于/src/data/certbot处-与ssl-dhparams相同。很抱歉，忘记回复，问题在于我的nginx和docker compose配置。谢谢你的帮助。
