K8s 管理系统项目[Jenkins Pipeline K8s环境–应用部署]

请添加图片描述

1. k8s-plantform-api-Pipeline

考虑到实际工作中前后端可能是不同的同学完成,一般Api部分完成后改动会比较小,web部分改动会比较频繁.于是将api和web分了2个pipeline实现

1.1 GIt仓库

  1. docker目录存放镜像构建相关文件
  2. k8s-plantform-api 存放api部分代码
  3. Jenkinsfile用作pipeline配置
  4. yaml用作生成k8s下k8s-plantform-api相关资源

请添加图片描述

1.1.1 docker目录

1.1.1.1 Dockerfile
# 设置基础镜像

#FROM harbor.intra.com/k8s-dashboard/api:v1

# 设置作者信息

# 创建目录

# 复制应用程序

# 安装 Go 和创建目录
RUN cd /etc/yum.repos.d  && \
    rm -f *.repo 
RUN cd /data/k8s-plantform&& \
    curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo && \

rm -f /data/*.txt
source ~/.profile
cd /data/k8s-plantform
go run main.go

1.1.2 k8s-plantform-api目录

1.1.2.1 config.go

数据库的配置会由configmap传递到容器,并由脚本替换

k8s-plantform-api/config/config.go

package config

import "time"

const (
	//监听地址
	ListenAddr = "0.0.0.0:9091"
	//kubeconfig路径
	Kubeconfig = "config/config"
	//pod日志tail显示行数
	PodLogTailLine = 2000
	//登录账号密码
	AdminUser = "admin"
	AdminPwd  = "123456"

	//数据库配置
	DbType = "mysql"
	DbHost = "Db_Ip"
	DbPort = Db_Port
	DbName = "k8s_dashboard"
	DbUser = "Db_User"
	DbPwd  = "Db_Pass"
	//打印mysql debug sql日志
	LogMode = false
	//连接池配置
	MaxIdleConns = 10               //最大空闲连接
	MaxOpenConns = 100              //最大连接数
	MaxLifeTime  = 30 * time.Second //最大生存时间
)

1.1.3 Jenkinsfile

2.1.2 k8s-plantform-web

2.1.2.1 vue.config.js

k8s-plantform-web/vue.config.js

const { defineConfig } = require('@vue/cli-service')

module.exports = defineConfig({
  devServer:{
    host: '0.0.0.0',  // 监听地址
    port: 9090,           // 监听端口
    open: true,            // 启动后是否打开网页
    allowedHosts: [
      'web.k8s.intra.com',
      '.intra.com'
    ],
  },
  // 关闭语法检测
  lintOnSave: false,
})

2.1.2.2 Config.js
