实践：devops之K8s环境持续部署

1、Kubectl 发布流水线

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-X2Q6MzL1-1688896509292)(https://bucket-hg.oss-cn-shanghai.aliyuncs.com/img/image-20230709101119001.png)]

CI流水线：

下载代码
构建单元测试
代码扫描
构建镜像
更新发布文件

CD流水线：

输入版本，从git下载部署文件；
使用kubectl发布；
使用kubectl回滚；

环境准备

jenkins

gitlab

sonarQube

harbor

使用之前的npm项目

使用之前的npm项目devops6-npm-service

如何构建，请看npm构建项目部分。

编辑index.html文件

<h1>VERSION: main</h1>

配置好sonar参数

创建sonar-project.properties文件

# 定义唯一的关键字
sonar.projectKey=devops6-npm-service

# 定义项目名称
sonar.projectName=devops6-npm-service

# 定义项目的版本信息
sonar.projectVersion=1.0
 
# 指定扫描代码的目录位置（多个逗号分隔）
sonar.sources=src
 
# 执行项目编码
sonar.sourceEncoding=UTF-8

# 指定sonar Server
sonar.host.url=http://172.29.9.101:9000

# 认证信息
sonar.login=admin
sonar.password=Admin@123

创建一条新pipeline

以原devops6-maven-service_CI为基础拷贝一条新流水线devops6-npm-service_K8SCI：

⚠️ 注意：但是这里的Git选项参数一直没效果，测试不出来，很奇怪。。。因此，就直接用默认的选项参数就好。

可以看待，前面几个过程都是ok的，这里上传制品过程，不需要。

创建harbor仓库

镜像命名规范：

修改本地 docker 服务使用 http 协议和私有仓库通信（否则会报错）

#配置可信任（如果仓库是HTTPS访问不用配置）
#在 daemon.json 中添加以下参数
[root@harbor ~]# vim /etc/docker/daemon.json #创建此文件，并写入以下内容
{
"insecure-registries": ["172.29.9.120"]

编写CI pipeline

创建k8sci.jenkinsfile

在回放里运行

然后将代码提交到共享库里。

准备k8s环境

启动好k8s环境

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-elTtOolP-1688896509305)(https://bucket-hg.oss-cn-shanghai.aliyuncs.com/img/image-20230704220639938.png)]

在devops06机器上安装kubectl工具

cat > /etc/yum.repos.d/kubernetes.repo << EOF
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1

然后把k8s集群master节点下的~/.kube/config文件拷贝到devops6机器~/.kube/目录下

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-nEALoTSP-1688896509305)(https://bucket-hg.oss-cn-shanghai.aliyuncs.com/img/image-20230704221711066.png)]

然后在k8s的2个节点先配置好修改本地 docker 服务使用 http 协议和私有仓库通信（否则会报错）

#配置可信任（如果仓库是HTTPS访问不用配置）
#在 daemon.json 中添加以下参数
[root@harbor ~]# vim /etc/docker/daemon.json #创建此文件，并写入以下内容
{
"insecure-registries": ["172.29.9.120"] 
}

#重启docker 服务
[root@harbor ~]# systemctl daemon-reload && systemctl restart docker

记得：只需要在node1 node2上配置就行。

自己k8s集群需不是一个ingress-controller。

这里之前已经部署好ingress-controller了。

配置下kubectl的自动补全

#安装软件包
yum install -y epel-release bash-completion

#执行命令
source /usr/share/bash-completion/bash_completion

source <(kubectl completion bash)
echo "source <(kubectl completion bash)" >> ~/.bashrc

自己部署应用测试

创建新命名空间devops6

[root@Devops6 ~]#kubectl create ns devops6

部署应用：

[root@Devops6 ~]#kubectl  -n  devops6 apply -f Deployment.yaml 
deployment.apps/devops6-npm-service created
service/devops6-npm-service created
ingress.networking.k8s.io/devops6-npm-service created

注意：这里直接加上命名空间后，应用就会直接被部署到此命名空间了。

[root@Devops6 ~]#kubectl get po -ndevops6

配置ingress域名解析：

[root@Devops6 ~]#kubectl get ingress -ndevops6

新建devops6-npm-service版本分支，特性分支

以main为基础新建devops6-npm-service版本分支RELEASE-1.1.1

修改index.html的内容为RELEASE-1.1.1。

运行一次CI流水线

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-4kNrjchh-1688896509307)(https://bucket-hg.oss-cn-shanghai.aliyuncs.com/img/image-20230705133823641.png)]

要记得改下这里的jenkinsfile文件：

成功生成镜像：

我们再来更新一个版本的应用程序看下

[root@Devops6 ~]#vim Deployment.yaml
将
- image: 172.29.9.120/devops6/devops6-npm-service:main-ed12ce10
替换为
172.29.9.120/devops6/devops6-npm-service:RELEASE-1.1.1-7d906f68

#然后部署应用：
[root@Devops6 ~]#kubectl apply -f Deployment.yaml -ndevops6

#验证
[root@Devops6 ~]#curl devops.test.com
<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width,initial-scale=1.0">
    <title>vuedemo</title>
  </head>
  <body>
    <div id="app">
      <h1>VERSION: RELEASE-1.1.1</h1>
    </div>
    <!-- built files will be auto injected -->

#可以看到，已经更新成功了。

我们来测试下回滚

回滚命令：

## 查看历史
kubectl rollout history deployment/anyops-devopsdocker-ui

## 查看具体某一个历史版本信息
kubectl rollout history deployment/anyops-devopsdocker-ui --revision=2

## 回滚上个版本 
kubectl rollout undo deployment/anyops-devopsdocker-ui -n anyops

## 回滚指定版本
kubectl rollout undo deployment/nginx --to-revision=2

REVISION  CHANGE-CAUSE

我们打算回滚到上个历史版本：

先来查看下当前应用版本：

watch -n 1 "curl devops.test.com"

watch -n 1 "curl -s devops.test.com"

开始回滚：

[root@Devops6 ~]#kubectl rollout undo deployment devops6-npm-service -ndevops6
deployment.apps/devops6-npm-service rolled back

回滚结果：

回滚成功。

这里调的是gitlab的api

调用gitlab api自动更新配置文件。

jenkins装一个插件HTTP Request

devops6-npm-service项目ProjectID为11。

将次helm chart推送到刚才创建的helm仓库

#先删除manifests目录
[root@Devops6 devops6-npm-service]#pwd
/root/devops6-npm-service
[root@Devops6 devops6-npm-service]#ls
charts  Chart.yaml  manifests  templates  values.yaml
[root@Devops6 devops6-npm-service]#rm -rf manifests/

#推送 （注意：这次试验这里是master分支）
cd existing_folder
git init
git remote add origin http://172.29.9.101:8076/devops6/devops6-helm-repo.git
git add .
git commit -m "Initial commit"
git push -u origin master

harbor上开启helm chart

默认harbor没有helm chart功能，需要另外配置下才行

配置

开启helm charts
./install.sh  --with-chartmuseum
helm repo add devops6repo http://172.29.9.120/chartrepo/devops6/  --username=admin --password=Harbor12345

配置完后，harbor界面就出现了helm chart选项了：
