1.创建Dockerfile文件

# This file is a template, and might need editing before it works on your project.FROM node:8.9.3WORKDIR /usr/src/appARG NODE_ENVENV NODE_ENV $NODE_ENVCOPY package.json /usr/src/app/RUN npm install --registry=https://registry.npm.taobao.orgCOPY . /usr/src/appCMD [ "npm", "start" ]# replace this with your application's default portEXPOSE 80

2.创建.gitlab-ci.yml文件

before_script:  #停止正在运行的容器  - "docker rm gpcmarket-ops-vue -f"job_test:  script:  #build镜像  - "docker build -t liyc/gpcmarket-ops-vue ."  #运行对外端口80  - "docker run --name gpcmarket-ops-vue -d -p 80:80 liyc/gpcmarket-ops-vue"  only:    - test  tags:    - shared1

这样每次test分支有commit时会自动构建镜像并运行一个新的docker容器，对外端口80。
