dashboard开发环境搭建

2019独角兽企业重金招聘Python工程师标准>>>

1.dashboard开发环境搭建(Linux -ubuntu 16.04.2)

参考：dashboard工程目录/docs/devel下的requirements-installation.md和getting-started.md

unbuntu安装 & java7安装

1）ubuntu 16.04.2 下载

地址：http://mirror.bjtu.edu.cn/ubuntu-releases/16.04.2/ubuntu-16.04.2-desktop-amd64.iso 虚拟机安装。

安装后升级linux（可选）

sudo apt-get update		
sudo apt-get upgrade

其中：
update 是同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。
upgrade 是升级已安装的所有软件包，升级之后的版本就是本地索引里的，因此，在执行 upgrade 之前一定要执行 update, 这样才能是最新的。

ubutun 版本验证命令：uname -r 或 lsb_release -a ：

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.2 LTS
Release:        16.04
Codename:       xenial

后续命令操作都切换到root下执行su root

2）网络设置

使用图形化界面修改，系统设置/硬件/网络/有线/选项/iov4设置.....

3）java(7+)下载安装：

Ubuntu16.04的安装源已经默认没有openjdk7了，所以要自己手动添加仓库，如下：

add-apt-repository ppa:openjdk-r/ppa   
apt-get update   
apt-get install openjdk-7-jdk
java -version

4) 其他相关下载

apt-get install curl   
apt-get install git
apt-get install openssh-server

其中：
curl 后续ubuntu下载东西需要用到，版本验证curl --version
git 之后从github上check出dashboard代码，版本验证git --version
openssh-server 使用ssh远程ubuntu

Docker(1.10+)安装&配置

1）升级source列表并保证https和ca证书成功安装

apt-get update
apt-get install apt-transport-https ca-certificates

2）增加新的GPG 密钥

apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

3）创建source列表里的docker.list

$ sudo bash -c 'echo "deb https://apt.dockerproject.org/repo ubuntu-xenial main" > /etc/apt/sources.list.d/docker.list'

4）安装docker

apt-get install docker.io	#安装docker
service docker start		#启动docker
service docker status		#docker是否启动
docker info			#docker基本信息，包括版本
docker run hello-world		#验证docker是否可用

5）docker配置

groupadd docker
usermod -aG docker root

6）中国官方镜像加速
修改 /etc/docker/daemon.json 文件并添加上 registry-mirrors 键值。

{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}

修改保存后重启 Docker 以使配置生效service docker restart。

go(1.7+)安装&环境配置&IDE

下载go1.8

wget https://storage.googleapis.com/golang/go1.8.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.8.linux-amd64.tar.gz
export PATH=$PATH:/usr/local/go/bin
echo "export PATH=$PATH:/usr/local/go/bin" >> ~/.profile
echo "export PATH=$PATH:/usr/local/go/bin" >> /etc/profile

验证

go version
echo $PATH

IDE使用：JetBrains Gogland

前端环境搭建：nodejs(5.1.1+)，npm(3+)，gulp(3.9+)

nodejs和npm 下载&验证：

curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
apt-get install -y nodejs	
node -v	 
npm -v  

Gulp下载&验证

npm install --global gulp-cli
npm install --global gulp
gulp -v

npm镜像

npm install cnpm -g --registry=https://registry.npm.taobao.org

cnpm跟npm用法完全一致，只是在执行命令时将npm改为cnpm

工程项目概况

从github上下载dashboard源码：git clone https://github.com/kubernetes/dashboard.git

前端：SPA, ES6/babel, Angular1.6, gulp, bower,karma, BrowerSync 后端：Go

构建

开发环境执行

npm install 设置环境变量KUBE_DASHBOARD_APISERVER_HOST为k8s的api server的ip端口。 执行gulp serve ，可访问http://localhost:9090

BrowserSync (9090) ---> Dashboard backend (9091) ---> Kubernetes API server (8080)

生产环节

编译代码执行gulp build：编译，压缩前台代码，编译后台代码到dist目录。
执行gulp serve:prod，可访问http://localhost:9090

Dashboard backend (9090) ---> Kubernetes API server (8080)

打包成docker镜像执行：gulp docker-image:canary

配置文件.babelrc

Babel的配置文件，该文件用来设置转码规则和插件，设置ES6

{
  "presets": ["es2015"]
}

相关预备知识

gulp

BrowerSync

Go

ES5 & ES6

ES5：严格模式，JSON，添加对象，额外的数组，Function.prototype.bind
ES6：let&const, 解构，箭头函数，默认参数，rest&spread，字符串模板，集合类型，模块，Promise，Class，Iterators, Generators, Proxies&Reflecion, Symbols....

Angular1.x

MVVM：视图 - 模型 - 视图模型

2.dashboard开发环境搭建(windows)

• Docker (1.10+)
• go (1.7+)
• nodejs (5.1.1+)
• npm (3+)
• java (7+)
• gulp (3.9+)

npm 配置

npm config set prefix "D:\node\node-global"
npm config set cache "D:\node\node-cache"
配置环境变量NODE_PATH   设置为node_modules的文件夹路径  D:\node\node-global\node_modules 
npm config set registry https://registry.npm.taobao.org

安装python2.7

安装vs expression 2013 for desk（VS2013_RTM_DskExp_CHS.iso）

npm config set python C:\Python27\python.exe  
npm config set msvs_version 2013 --global  
npm install  

再在gitbash里手动执行build/postinstall.sh

go包管理

go get -u github.com/kardianos/govendor Warning： 需要把 $GOPATH/bin/ 加到 PATH 中。 https://segmentfault.com/a/1190000009268696

跨平台

1）const sourceGopath = ${conf.paths.backendTmp}${path.delimiter}${conf.paths.backendVendor}; 路径分隔符，文件分隔符
2）gocommad.js里的which命令改成where
3）java -Dfile.encoding=utf-8 i18n下文件的编码问题
-jar F:\WORK\work_go\src\github.com\kubernetes\dashboard.tools\xtbgenerator\bin\XtbGenerator.jar --lang en --xtb_output_file F:\WORK\work_go\src\github.com\kubernetes\dashboard\i18n\messages-en.xtb --js F:\WORK\work_go\src\github.com\kubernetes\dashboard.tmp\serve*.js --js F:\WORK\work_go\src\github.com\kubernetes\dashboard.tmp\messages_for_extraction*.js --translations_file F:\WORK\work_go\src\github.com\kubernetes\dashboard\i18n\messages-en.xtb MalformedByteSequenceException: 3 字节的 UTF-8 序列的字节 3 无

4）18n

let command = `java -Dfile.encoding=utf-8 -jar ${conf.paths.xtbgenerator} --lang ${langKey}` +
  
//let messageVarPrefix = filePath.toUpperCase().split('/').join('_').replace('.HTML', '');
  let messageVarPrefix = filePath.toUpperCase().replace(/\\/g,"\/").split('/').join('_').replace('.HTML', '');
  
/*
* gulp-google-closure-compiler: deploy/helpsection/userhelp.html.js:5: ERROR - Parse error. Hex digit expected
 $templateCache.put('deploy\helpsection\userhelp.html', ' 
 
 ');
 报错信息说是发现非法16进制数据，这个问题非常蹊跷，也是windows平台和linux平台的路径分隔符不一致所致，是上面的\userhelp.html造成的，因为\u在js中代表后面接着的是16进制数，打开build/i18n.js,将：
 * */
file.moduleContent = `` +
    `import module from 'index_module';\n\n${file.messages}\n` +
    `module.run(['$templateCache', ($templateCache) => {\n` +
    `    $templateCache.put('${filePath.replace(/\\/g,"\\\\")}', '${content}');\n` +
    `}]);\n`;

5）gocommand.js

import path from 'path';
const sourceGopath = `${conf.paths.backendTmp}${path.delimiter}${conf.paths.backendVendor}`;
// Add the project's required go tools to the PATH.
const devPath = `${process.env.PATH}${path.delimiter}${conf.paths.goTools}/bin`;

6）build.js

let searchPath = [
// To resolve local paths.
path.relative(conf.paths.base, conf.paths.prodTmp),
// To resolve bower_components/... paths.
path.relative(conf.paths.base, conf.paths.base)+'/',
  ];

7）package.json

"babel-core": "~6.24.0",
"babel-loader": "~7.0.0",
"babel-preset-es2015": "~6.24.0",

babel版本问题，1.6.3里的版本有问题会报错

8）dashboard ENONE 第一次使用exe结尾，以后不用exe结尾也可以启动

9）minikube本地安装
kubectl config view 获取kubeconfig
证书访问https

--insecure-port=9091
--apiserver-host=https://192.168.0.9:8443
--kubeconfig=F:\temp\kubeconfig  

安装minikube https://kubernetes.io/docs/getting-started-guides/minikube/

使用到Angular Material，依赖angular-animate, angular-aria(无障碍), angular 使用flex布局，封装flex成自己的样式layout-*，再把layout-*样式和属性关联，使用时直接使用属性。 支持-sm, -md, -gt等自适应的后缀(600,960,1200)
