由于在服务器上打包发布vue项目很慢，也很消耗服务器资源，所有把这个过程放到本地来进行，本地打包好项目后提交到git. openshift build 下载源代码后直接使用打包好的文件 启动 express服务器

1. 覆盖openshift 已经有的s2i 中nodejs 的脚本代码

在根目录下面创建文件夹 .s2i\bin ，在 .s2i\bin 创建两个文件 assemble run
assemble文件内容：
#!/bin/bash

# Prevent running assemble in builders different than official STI image.
# The official nodejs:6-onbuild already run npm install and use different
# application folder.
[ -d "/usr/src/app" ] && exit 0

set -e

# FIXME: Linking of global modules is disabled for now as it causes npm failures
#        under RHEL7
# Global modules good to have
# npmgl=$(grep "^\s*[^#\s]" ../etc/npm_global_module_list | sort -u)
# Available global modules; only match top-level npm packages
#global_modules=$(npm ls -g 2> /dev/null | perl -ne 'print "$1\n" if /^\S+\s(\S+)\@[\d\.-]+/' | sort -u)
# List all modules in common
#module_list=$(/usr/bin/comm -12 <(echo "${global_modules}") | tr '\n' ' ')
# Link the modules
#npm link $module_list

safeLogging () {
    if [[ $1 =~ http[s]?://.*@.*$ ]]; then
        echo $1 | sed 's/^.*@/redacted@/'
    else
        echo $1
    fi
}

shopt -s dotglob
echo "---> Installing application source ..."
mv /tmp/src/* ./

if [ ! -z $HTTP_PROXY ]; then
    echo "---> Setting npm http proxy to" $(safeLogging $HTTP_PROXY)
    npm config set proxy $HTTP_PROXY
fi

if [ ! -z $http_proxy ]; then
    echo "---> Setting npm http proxy to" $(safeLogging $http_proxy)
    npm config set proxy $http_proxy
fi

if [ ! -z $HTTPS_PROXY ]; then
    echo "---> Setting npm https proxy to" $(safeLogging $HTTPS_PROXY)
    npm config set https-proxy $HTTPS_PROXY
fi

if [ ! -z $https_proxy ]; then
    echo "---> Setting npm https proxy to" $(safeLogging $https_proxy)
    npm config set https-proxy $https_proxy
fi

# Change the npm registry mirror if provided
if [ -n "$NPM_MIRROR" ]; then
    npm config set registry $NPM_MIRROR
fi

echo "---> Building your Node application from source"
npm install express http-proxy-middleware ejs

# Fix source directory permissions
fix-permissions ./

run 文件内容
#!/bin/bash

# S2I run script for the 'nodejs' image.
# The run script executes the server that runs your application.
#
# For more information see the documentation:
#   https://github.com/openshift/source-to-image/blob/master/docs/builder_image.md
#

set -e

if [ -e "/opt/app-root/etc/generate_container_user" ]; then
  source /opt/app-root/etc/generate_container_user
fi

# Runs the nodejs application server. If the container is run in development mode,
# hot deploy and debugging are enabled.
run_node() {
  echo -e "Environment: \n\tDEV_MODE=${DEV_MODE}\n\tNODE_ENV=${NODE_ENV}\n\tDEBUG_PORT=${DEBUG_PORT}"
  if [ "$DEV_MODE" == true ]; then
    echo "Launching via nodemon..."
    exec nodemon --debug="$DEBUG_PORT"
  else
    echo "Launching via npm..."
    exec npm run -d $NPM_RUN
  fi
}

#Set the debug port to 5858 by default.
if [ -z "$DEBUG_PORT" ]; then
  export DEBUG_PORT=5858
fi

# Set the environment to development by default.
if [ -z "$DEV_MODE" ]; then
  export DEV_MODE=false
fi

# If NODE_ENV is not set by the user, then NODE_ENV is determined by whether
# the container is run in development mode.
if [ -z "$NODE_ENV" ]; then
  if [ "$DEV_MODE" == true ]; then
    export NODE_ENV=development
  else
    export NODE_ENV=production
  fi
fi

# If the official dockerhub node image is used, skip the SCL setup below
# and just run the nodejs server
if [ -d "/usr/src/app" ]; then
  run_node
fi

# Allow users to inspect/debug the builder image itself, by using:
# $ docker run -i -t openshift/centos-nodejs-builder --debug
#
[ "$1" == "--debug" ] && exec /bin/bash

run_node

2. 配置vue 项目服务器接口代理

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {
      '/server': {
        target: 'http://health-server.shiwaixiangcun.cn',
        changeOrigin: true
      }
    },
  }
.....
}

3. 配置启动express服务器的文件

在根路径下面创建server.js文件
var express = require('express');
var app = express();
var proxyMiddleware = require('http-proxy-middleware')
var config = require('./config')
var proxyTable = config.dev.proxyTable

app.set('port', (process.env.PORT || 8080));           //设置端口
app.use(express.static(__dirname + '/dist',{maxAge: 24*60*60*1000}));         //设置静态文件目录

// views is directory for all template files
app.set('views', __dirname + '/dist');                 //设置页面文件目录
app.set('view engine', 'ejs');                          //设置模板引擎为ejs

app.get('/', function (request, response) {
  response.render('index');
});

// proxy api requests
Object.keys(proxyTable).forEach(function (context) {
  var options = proxyTable[context]
  if (typeof options === 'string') {
    options = {target: options}
  }
  app.use(proxyMiddleware(options.filter || context, options))
});

app.get('*', function (request, response) {
  //404
  response.render('index');
});

app.listen(app.get('port'), function () {             //启动服务器，监听上面设置的端口
  console.log('Node app is running on port', app.get('port'));
});

4. package.json 添加script

"scripts": {
    "dev": "webpack-dev-server --inline --progress --config build/webpack.dev.conf.js",
    "start": "node server.js",
    "build": "cnpm install && node build/build.js"
  }
