一、Docker的安装
参考：https://segmentfault.com/a/1190000014066388?utm_source=tag-newest
二、Docker Compose的安装
参考：https://segmentfault.com/a/1190000007597694
问题：ubuntu上安装docker-compose遇到Permission denied问题
解决：执行sudo -i，提示输入用户密码，输入密码后进入超级用户（root）模式，重新执行上述命令，一切正常

三、安装最新版nodejs
参考：https://blog.csdn.net/well2049/article/details/79138045
PAA安装：Ubuntu环境下安装nodejs和npm
参考：https://blog.csdn.net/wangtaoking1/article/details/78005038
nodejs npm常用命令:
https://blog.csdn.net/pengpegv5yaya/article/details/51912321
问题：nodejs版本问题
nodejs -v(PAA安装)
node -v（apt安装）
nodejs的卸载：
sudo apt-get remove --purge nodejs
四、Clone the Git repository
参考：https://redash.io/help/open-source/dev-guide/docker
问题：Permission denied (publickey). fatal: Could not read from remote repository
解决：https://www.cnblogs.com/wmr95/p/7852832.html
Github登录：https://github.com/settings/keys
五、webpack的安装
注意：webpack3和webpack4的区别
升级至webpack4会出现很多错误，建议使用webpack3
注意：全局安装与本地安装的区别
https://www.cnblogs.com/PeunZhang/p/5629329.html
全局安装：npm install webpack -g
参数-g的含义是代表安装到全局环境里面，包安装在Node安装目录下的node_modules文件夹中
本地安装：npm install webpack 或 npm install webpack --save-dev等
参数–save-dev的含义是代表把你的安装包信息写入package.json文件的devDependencies字段中，包安装在指定项目的node_modules文件夹下。
全局安装
npm install [email protected] -g
在当前项目的根目录里面也安装一个webpack
npm install [email protected] --save-dev
这样就可以在你的webpack.config.js里面方便的引用webpack
六、webpack-dev-server的安装
全局安装
npm install webpack-dev-server -g
本地安装
npm install webpack-dev-server --save-dev
七、Create Docker Services
docker-compose up
八、Install npm Packages
npm install
问题：Cannot find module '/root/redash/node_modules/uglifyjs-webpack-plugin/lib/postinstallwebpack安装出现uglifyjs-webpack-plugin postinstall的错误
解决：https://zhidao.baidu.com/question/1929987072049389427.html
九、Create Database
创建tables
docker-compose run --rm server create_db
创建database
docker-compose run --rm postgres psql -h postgres -U postgres -c “create database tests”
十、Run webpack Dev Server
方法一：
all Docker services are running (can be started either by docker-compose up or docker-compose start)
Redash is available at http://localhost:5000/
方法二：
use webpack’s dev server
（npm run build和npm run start）
the dev server is available at http://localhost:8080
All the API calls are proxied to localhost:5000 (the server running in Docker).
问题：[HPM] Error occurred while trying to proxy request /api/session from localhost
解决：https://nodejs.org/api/errors.html#errors_common_system_errors
ECONNREFUSED (Connection refused): No connection could be made because the target machine actively refused it. This usually results from trying to connect to a service that is inactive on the foreign host.
