node.js - 用于节点服务器的 Docker 撰写失败

问题描述

我编写了一个通过 npm 脚本 (npm run dev) 运行的节点服务器。我为它创建了以下 Dockerfile：

FROM node:10.12.0

ARG COMMIT_REF
ARG BUILD_DATE

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install

COPY . .

ENV APP_COMMIT_REF=${COMMIT_REF} \
    APP_BUILD_DATE=${BUILD_DATE}

ENV PORT 8009

EXPOSE 8009

CMD [ "npm", "run", "server" ]

构建和运行服务器：
docker build . -t server并且docker run -it -p 8009:8009 --env-file .env server运行良好，服务器在端口 8009 上运行和公开。

不，我尝试docker-compose.yml为它创建。这是我写的：

version: '3'

services:
    server:
        image: server
        build: .
        env_file:
            - .env
        volumes:
            - .:/usr/src/app
            - /usr/src/app/node_modules
        working_dir: /.
        ports:
            - 8009:8009

当我使用它运行它时，docker-compose up我得到：

Starting bed_server_1 ... done
Attaching to bed_server_1
server_1  | npm ERR! path /package.json
server_1  | npm ERR! code ENOENT
server_1  | npm ERR! errno -2

bed_server_1 exited with code 254

知道有什么问题吗？

解决方案

The image's CMD runs npm run server in whatever directory it starts up in. The docker-compose.yml working_dir: / tells the container to start up in the root directory. That's not what you want; you want the container to start up in the directory you COPY'd its source code to.

You will probably fix your immediate issue if you remove the working_dir: line.
