Docker compose无法建立：COPY失败：，在根目录中找不到package.json

Question

首次使用docker。请帮忙！

我明白了。我该如何解决？

Step 3/7 : COPY package*.json ./
ERROR: Service 'buyer' failed to build: COPY failed: no source files were specified

我的代码文件在一个文件夹下运行。我将它们放在其他文件夹中以创建docker。我的文件结构如下所示

├── buyer
│   ├── Dockerfile
│   ├── client.js
│   ├── index.html
│   └── iotaModule.js
├── seller
│   ├── Dockerfile
│   ├── index.js
│   └── iotaModule.js
├── docker-compose.yml
├── node_modules
├── package.json
├── package-lock.json
├── .dockerignore

我的卖方dockerfile

FROM node:10

WORKDIR /seller

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 3000

CMD [ "node", "index.js" ]

我的买方dockerfile

FROM node:10

WORKDIR /buyer

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 8080

CMD [ "node", "client.js" ]

我的docker-compose.yml

version: '3'

services:
  seller:
    container_name: docker_seller
    build: seller/
    ports:
      - '3000:3000'
    depends_on:
      - buyer
  buyer:
    container_name: docker_buyer
    build: buyer/
    ports:
      - '8080:8080'

<%# app/views/reservation_mailer/confirmation_email.text.erb %> Hello, You are registering for <%= @event.name %>. Click here to confirm your email: <%= event_reservation_url(@event, @reservation) %>. Thanks 无法正常工作。我将package，json放在子文件夹中，并且可以正常工作。可能不是最好的方法。
