Question

这让我疯了几个小时。我想要一个docker-compose文件，它只是构建一个图像，创建一个容器，然后执行一个简单的脚本。

我尽可能简单地重新创建了这个问题

app.js

const fs = require("fs");
const util = require("util");
const sqlite3 = require("sqlite3");

console.log("DOING NOTHING");

的package.json

{
    "name": "example",
    "version": "0.1.0",
    "author": "shatnerz",
    "main": "app.js",
    "scripts": {
        "start": "node app.js"
    },
    "dependencies": {
        "sqlite3": "4.0.0"
    }
}

Dockerfile

FROM node:9.11.1-alpine

ADD . /home/example
WORKDIR /home/example
# RUN npm update -g
RUN npm install

CMD ["npm", "run", "start"]

搬运工-compose.yml

version: '3.6'

services:
  example:
    build: .
    image: shatnerz/example
    container_name: shatnerz-example
    volumes:
      - .:/home/example
    command: ["npm", "run", "start"]

当我尝试使用docker compose时，我得到了

$ docker-compose up --build

我尝试过不同版本的节点并使用ubuntu图像而不是alpine无效。我得到这个错误基本上是每个案例，但不知怎的docker run shatnerz/example按预期工作。

$ docker run shatnerz/example

> example@0.1.0 start /home/example
> node app.js

DOING NOTHING

令人难以置信的是令人沮丧。我一直盯着这个太久了。我不再进步了。我还将docker-compose和docker更新为最新版本。

我的node-modules*

中有.dockerignore

编辑：有趣的是，我在尝试从sublime运行app.js时遇到类似的错误，这导致认为它可能与stdin和stdout有关

Answer 1

尝试从docker-compose.yml

中删除以下行

volumes:
  - .:/home/example
command: ["npm", "run", "start"]

由于您已在docker-image中添加了这些参数和所需文件。

请让我知道 - 你的输出，以便我可以进一步帮助你。

Answer 2

奇怪的是，我已经能够通过运行来解决相同的错误消息 sudo npm install直接在我的计算机上，然后是docker-compose down和docker-compose up --build

Docker和Node - 使用docker-compose时获得“ELIFECYCLE”，使用`docker run`
