2. 步骤
2.1 准备工作
设置代理不然去git拿文件的时候会遇到麻烦
git config --global http.proxy socks5://192.168.0.108:1080
git config --global https.proxy socks5://192.168.0.108:1080git config --global --unset http.proxy
git config --global --unset https.proxy
编辑客户机hosts, 映射子域名 192.168.0.103 jenkins.k8s-t2.com 2.2 安装
2.2.1 用jenkins原站for k8s的安装仓方法安装
获取
git clone https://github.com/scriptcamp/kubernetes-jenkins
建个namespace
kubectl create ns devops-tools 编辑 volume.yaml设置/data0/jenkins-volume为存储地, 节点 k8s-master-0

2.2.2 Helm 安装 添加jenkins来源: helm repo add jenkinsci https://charts.jenkins.io helm repo update helm search repo jenkinsci 可知当前版本为:
NAME CHART VERSION APP VERSION DESCRIPTION
jenkinsci/jenkins 4.3.26 2.401.1 Jenkins - Build great things at any scale! The ...获取到本地并解压 helm fetch jenkinsci/jenkins tar -zxvf jenkins.tgz 编辑 values.yaml
ingress:#enabled: falseingress:enabled: true# See https://kubernetes.io/blog/2020/04/02/improvements-to-the-ingress-api-in-kubernetes-1.18/#specifying-the-class-of-an-ingress# 需注明用的是哪个ingress class因为之前装的是ingress-nginx, 所以这里填nginxingressClassName: nginx# Set this path to jenkinsUriPrefix above or use annotations to rewrite pathhostName: jenkins.k8s-t2.com
注意ingress需指定对应的 ingressClassName 执行安装
helm upgrade --install jenkins --namespace default \-f values.yaml \jenkins/jenkins# 过程大概要30分钟NOTES:
1. 获取admin登录密码 Get your admin user password by running:kubectl exec --namespace default -it svc/jenkins -c jenkins -- /bin/cat /run/secrets/additional/chart-admin-password echo
2. Visit http://jenkins.k8s-t2.com3. Login with the password from step 1 and the username: admin
4. Configure security realm and authorization strategy
5. Use Jenkins Configuration as Code by specifying configScripts in your values.yaml file, see documentation: http://jenkins.k8s-t2.com/configuration-as-code and examples: https://github.com/jenkinsci/configuration-as-code-plugin/tree/master/demos获知部署后的情况

- 启动pod时出现 default-scheduler 0/3 nodes are available: 1 node(s) had untolerated taint {node-role.kubernetes.io/control-plane: } 查找安装的目标Server是否有污点 node-role.kubernetes.io/control-plane有则去掉或修改
- 在jenkins安装插件时出现: unable to find valid certification path to requested target 解决办法手动安装 skip-certificate-check到这里下载skip-certificate-check | Jenkins plugin安装最新版本目前是1.1 设置git仓库时提示 stderr: No ECDSA host key is known for and you have requested strict checking. 解决办法 Manage Jenkins Security Git-Host-Key-Verification 修改为 No verificationssh - stderr: No ECDSA host key is known for github.com and you have requested strict checking - Ask Ubuntu
