使用 Yarn 依赖项为 Node 应用程序构建 Docker 镜像

Question

我正在尝试为使用纱线安装依赖项的节点应用程序构建 docker 映像。我的 Dockerfile 看起来像这样：

 FROM node:7
WORKDIR /app
COPY package.json /app
RUN yarn install
COPY . /app
CMD npm run develop
EXPOSE 8000

当我在本地机器上运行 yarn install 时，一切都运行良好，但是当我进行 docker build 时，我收到了这个永远阻塞的错误。

**docker build -t  rs  .**

请阅读 babeljs.io/env 进行更新！

控制台永远停留在这个阶段。我该如何解决这个问题。

Answer 1

Dockerfile

FROM node:6.9.5-alpine
RUN mkdir -p /code
WORKDIR /code
ADD . /code
RUN npm install -g -s --no-progress yarn && \
    yarn && \
    yarn run build && \
    yarn cache clean
CMD [ "npm", "start" ]
EXPOSE 8080

docker-compose.yml

version: '2'
services:
  sample-app:
    image: sample-node-yarn-app
    ports:
      - "8080:8080"

创建泊坞窗镜像

docker build -t sample-node-app .

跑步

docker-compose up -d

Answer 2

在构建映像之前，您应该首先运行 yarn install 以生成一个 yarn锁定文件（yarn.lock）。然后确保将它与 package.json 一起复制。您的 dockerfile 应如下所示：

FROM node:7 
WORKDIR /app 
COPY package.json /app 
COPY yarn.lock /app
RUN yarn install 
COPY . /app 
CMD npm run develop 
EXPOSE 8000

有了这个，构建映像时所有依赖项都应该成功安装
