Question

我是docker build功能的新手。我正在尝试为我的node.js应用程序创建docker映像，但是我遇到了问题。
1）它显示映像已创建，但是当我尝试docker运行

之类的给定错误时

"module.js:550
    throw err;
    ^

Error: Cannot find module '

我认为我的docker文件存在一些问题。我创建的，但没有得到确切的问题是什么我的Dockerfile

FROM ubuntu:16.04
RUN apt-get update -y 
RUN apt-get install g++ -y 
RUN apt install curl -y 
RUN curl --silent --location https://deb.nodesource.com/setup_8.x — Node.js 8 LTS "Carbon" |  bash -
RUN apt-get install --yes nodejs
RUN apt-get install --yes build-essential
# check the path 
WORKDIR /usr/src/app

COPY package*.json ./
RUN npm install
COPY . .
EXPOSE  9012
CMD ["node", "app.js"]

另请参阅my package.json以获取更多信息。模块。

当已经有official ones时，为什么要用ubuntu制作nodejs图像。

我看到了问题-您对Dockerfile进行了过度设计，并采取了不必要的步骤。

修复您的Dockerfile，然后重试：

FROM node:8-alpine3.9

RUN apk update
RUN apk add --no-cache g++ make python python-dev
RUN rm -rf /var/cache/apk/*

WORKDIR /app

COPY package*.json ./

RUN npm i

COPY . .

EXPOSE  9012
CMD node app.js

在上一次合作中，我发现这是代码中的错字，您需要从不存在的文件夹中获取文件。

"module.js:550 throw err; ^ Error: Cannot find module '../dFarmUserService/controllers/ClientRegisterController'

因此将其固定在一起：）
