01-Jenkins部署

前提条件

此文档依赖于基础环境配置文档，运行K8s集群并配置NFS存储。

参考文档：

《00-devops8基础环境配置(重要)》 http://localhost:3000/docs/devops8-basic-test-environment

代码库地址：https://gitee.com/onlyonexl/myiac-gitee

Step1 镜像配置

Docker镜像：

docker pull jenkins/jenkins:2.415-jdk11
docker pull jenkins/inbound-agent:latest

## LoadDockerImage
kind load  docker-image jenkins/jenkins:2.415-jdk11 --name devopscluster
kind load  docker-image jenkins/inbound-agent:latest --name devopscluster

以上2个镜像拉取速度很慢哦：（耐心等待一会儿哦）

Step2 部署Jenkins

已经编写好了一套K8s 清单文件和一个声明式的Argo APP。【具体参考代码库】，我们直接拉取代码执行就好。

[root@devops8 jenkins]#pwd
/root/myiac-gitee/devops/jenkins
[root@devops8 jenkins]#ls
agent-manifests  jenkins-agent-argoapp.yaml  jenkins-argoapp.yaml  manifests  run.sh
[root@devops8 jenkins]# sh -x run.sh 
+ kind load docker-image jenkins/jenkins:2.415-jdk11 --name devopscluster
Image: "jenkins/jenkins:2.415-jdk11" with ID "sha256:27aa51b3ca68eb5974570b2f685c948b4bfa60b41c5af4807a05411f11333457" found to be already present on all nodes.
+ kind load docker-image jenkins/inbound-agent:latest --name devopscluster
Image: "jenkins/inbound-agent:latest" with ID "sha256:bf21eca245df406d71cbc13bbfdbf51c69b491041e51aff052e9f3cce9fab10f" found to be already present on all nodes.
+ mkdir -p /data/storage/kubernetes/jenkins
+ chmod -R 777 /data/storage/kubernetes/jenkins
+ kubectl -n argocd apply -f jenkins-argoapp.yaml
application.argoproj.io/jenkins created
+ mkdir -p /data/storage/kubernetes/jenkins-build-cache
+ chmod -R 777 /data/storage/kubernetes/jenkins-build-cache
+ mkdir -p /data/storage/kubernetes/jenkins-workspace
+ chmod -R 777 /data/storage/kubernetes/jenkins-workspace
[root@devops8 jenkins]#

添加Hosts

192.168.1.200  jenkins.idevops.site

这里，我们看下本次涉及的相关配置文件

Step3 Jenkins初始化配置

从日志中获取解锁秘钥：在ArgoCD选中jenkins pod 然后进入LOGS菜单。

web访问jenkins.idevops.site

【注意：插件安装界面，选择自定义，然后什么插件都不选择哈避免网络问题】

Step4 创建Agent

http://jenkins.idevops.site/

新增节点，填写节点信息：

填写配置：

这里只需填写执行器数量就行，其他后面有需要可以再填：

获取密钥信息：

baf1cddeb7562e8733391ad0b9f59cc863351bfc054543c1cfadf27c729f514b

更新此处配置：

cd /root/myiac-gitee/devops/jenkins/agent-manifests
#vim agent-deployment.yaml

更新完代码，记得推送，再拉取代码。

[root@devops8 myiac-gitee]#git push
warning: push.default is unset; its implicit value is changing in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the current behavior after the default changes, use:

  git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

  git config --global push.default simple

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

Step5 部署Agent

#注意：这部分在之前的代码里已经创建过了哦,这里不需要再创建了。
## Jenkins build cache
#mkdir -p /data/storage/kubernetes/jenkins-build-cache
#chmod -R 777 /data/storage/kubernetes/jenkins-build-cache

## Jenkins agent build workspace
#mkdir -p  /data/storage/kubernetes/jenkins-workspace
#chmod -R 777 /data/storage/kubernetes/jenkins-workspace


[root@devops8 jenkins]#pwd
/root/myiac-gitee/devops/jenkins
[root@devops8 jenkins]#ls
agent-manifests  jenkins-agent-argoapp.yaml  jenkins-argoapp.yaml  manifests  run.sh
[root@devops8 jenkins]#kubectl -n argocd apply -f jenkins-agent-argoapp.yaml 
application.argoproj.io/jenkins-agent created

报错解决

遇到Agent日志出现下面错误，需要安装Instance identity插件解决。【记得插件安装完成后重启Jenkins】

SEVERE: http://jenkins.jenkins.svc.cluster.local:8080/tcpSlaveAgentListener/ appears to be publishing an invalid X-Instance-Identity.

java.io.IOException: http://jenkins.jenkins.svc.cluster.local:8080/tcpSlaveAgentListener/ appears to be publishing an invalid X-Instance-Identity.
