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：
bash
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。
bash
[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
bash
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
- 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：
bash
baf1cddeb7562e8733391ad0b9f59cc863351bfc054543c1cfadf27c729f514b- 更新此处配置：
bash
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。
bash
[root@devops8 myiac-gitee]#pwd
/root/myiac-gitee
[root@devops8 myiac-gitee]#git add -A
[root@devops8 myiac-gitee]#git commit -m"commit"

#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。

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】
bash
SEVERE: http://jenkins.jenkins.svc.cluster.local:8080/tcpSlaveAgentListener/ appears to be publishing an invalid X-Instance-Identity.
5
java.io.IOException: http://jenkins.jenkins.svc.cluster.local:8080/tcpSlaveAgentListener/ appears to be publishing an invalid X-Instance-Identity.

- jenkins重启后，观察
至此，以上jenins已安装完成。
FAQ
记得push代码
更新完本地仓库里的代码后，一定要先推送到gitee里，不然argocd还是拉取的旧的代码。
本次安装的插件
Instance identity插件
pipeline插件--pipeline流水线
Role-based Authorization Strategy的授权插件
Pipeline Utility Steps插件--帮我们处理yaml文件和json文件
Stage View插件--查看构建状态
timestamps插件--解决时间日志报错问题
pipeline util插件--
