Question

我正在尝试为使用yarn来安装依赖项的节点应用程序构建一个docker镜像。我的Dockerfile如下所示：

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

当我在本地计算机上运行yarn install时，每个东西都运行良好但是当我进行docker构建时，我得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！

控制台永远处于这个阶段。我该怎么办呢。

Answer 1

在构建映像之前，首先应运行yarn install以生成yarn lockfile（ yarn.lock ）。然后确保将其与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，所有依赖项应该在构建映像时成功安装

Answer 2

您可以通过使用预定义的yarn docker映像来简化上述答案。我们在此假设此图像仅用于开发目的。对于生产模式，您应该只考虑最小的二进制文件，例如node。

FROM gmolaire/yarn:1.22.4_12.18.3-alpine3.12

WORKDIR /usr/local/app
ADD . .

RUN yarn install && \
    yarn build

EXPOSE 8080

CMD [ "yarn", "run", "develop" ]

<强> 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

<强>搬运工-compose.yml

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

创建泊坞窗图片

docker build -t sample-node-app。

生成

docker-compose up -d

使用Yarn依赖关系为Node应用程序构建Docker镜像
