k8s笔记14--初次体验 开源云原生软件交付平台zadig

1 介绍

Zadig 是 KodeRover 公司基于 Kubernetes 自主设计、研发的开源分布式持续交付 (Continuous Delivery) 产品，为开发者提供云原生运行环境，支持开发者本地联调、微服务并行构建和部署、集成测试等。Zadig 内置了面向 Kubernetes、Helm、云主机/物理机、大体量微服务等复杂业务场景的最佳实践，为工程师一键生成自动化工作流 (workflow)。Zadig 不改变现有习惯和流程，几乎兼容所有软件架构，无缝集成 GitHub/GitLab、Jenkins、多家云厂商等，运维成本极低。

目标是通过云原生技术的运用和工程产品赋能，打造极致、高效、愉悦的开发者工作体验，让工程师成为企业创新的核心引擎。

业务架构如下图所示:

2 部署&测试

2.1 部署

1 软硬件环境
硬件:
4CPU 8G内存 32G存储
软件:
Ubuntu 18.04 x86 Server
K8S 1.19.3

2 部署

wget curl -SsL https://github.com/koderover/zadig/releases/latest/download/all_in_one_install_quickstart.sh

export IP="192.168.2.21" # 此处 ip 填写部署节点的IP即可
export PORT=30000
./all_in_one_install_quickstart.sh 

部署主要步骤如下:

main() {
  printLogo
  logSuccess "Welcome to the Koderover Installer"
  logInfo "Checking system for requirements..."
  setTimer
  checkForRoot
  getSystemInfos
  preflightCheck
  reportTime "preflight check"
  setTimer
  mkdir -p ${KR_HOME}/mypkg
  reportTime "install preparation"
  setTimer
  installCri
  installKubernetesHost
  prepareKubernetes
  reportTime "infrastructure installation"
  setTimer
  installZadig
  postInstallZadig
  reportTime "zadig installation"
}

部署过程会检查系统环境, 主要输出:

 infrastructure installation completed in 15 minute(s) and 23 second(s)

安装完成后, 通过kubeclt 可以安到如下 deploy 和 statefulset

2.2 测试

通过 ${ip}:30000 访问zadig, 账户密码为 admin/zadig

集群管理:
在 系统设置-集群管理-新建 中添加加新集群, 那么就可以在新集群中添加 zadig 的agent, 从而可以将 zadig 的任务调度到其它集群执行, 接入命令和最后效果如下:

kubectl apply -f "http://192.168.2.21:30000/api/aslan/cluster/agent/61f4d84d899cbdea3539f2ab/agent.yaml?type=deploy"

3 注意事项

1. All in One 一键安装原理是在一台机器上初始化K8S 安装环境, 然后在 k8s 集群内部部署zadig 服务, 因此系统环境要满足K8s 部署的环境.
2. 升级

helm --kubeconfig .kube/config-zadig upgrade zadig-zadig koderover-chart/zadig --namespace zadig --version=1.12.0
如果需要定制 zadig 配置项，可以 helm fetch koderover-chart/zadig 下载 helm chart 安装包，按需更改 values.yaml 文件
