我正在尝试为使用yarn来安装依赖项的 Node 应用程序构建docker镜像。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
当我在本地计算机上运行yarn install时，每件事都运行良好，但是当我执行docker build时，此错误永远存在。
**docker build -t rs .**

控制台永远保持在此阶段。请问我该如何解决。
最佳答案
在构建镜像之前，您应该首先运行yarn install生成 yarn 锁文件( yarn.lock )。然后确保将其与package.json一起复制。您的dockerfile应该如下所示:
FROM node:7
WORKDIR /app
COPY package.json /app
COPY yarn.lock /app
RUN yarn install
COPY . /app
CMD npm run develop
EXPOSE 8000
这样，在构建镜像时所有依赖项都应成功安装
