使用docker 在linux中开发或打包示例

windows的话 volume只能挂载在 c:/Users/ 下

# linux:alpine,node,npm
FROM registry.cn-qingdao.aliyuncs.com/wumi/docker_for_node:0.0.1

RUN mkdir /data

COPY ./package.json /data/

WORKDIR /data

RUN npm i --registry=https://registry.npm.taobao.org

EXPOSE 8080

# 运行
# docker build -t vue_docker .
# docker run --rm -v "/$(PWD)":/data -p 8000:8080 -it vue_docker
