构建带maven环境的jenkins 镜像

# 构建带 maven 环境的 jenkins 镜像
docker build -t 192.168.113.122:8858/library/jenkins-maven:jdk-11 .# 登录 harbor
docker login -uadmin 192.168.113.122:8858# 推送镜像到 harbor

[root@kubeadm-master1 jenkins-maven]# docker push 108.1.1.12:8858/wolfcode/jenkin-maven:v1

安装jenkins

创建pvc,pv

[root@kubeadm-master2 jenkins]# cat pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:name: pv6
spec:capacity:storage: 5GiaccessModes:- ReadWriteManystorageClassName: "managed-nfs-storage6"persistentVolumeReclaimPolicy: Retainnfs:path: /root/data/pv6server: 192.168.1.209
[root@kubeadm-master2 jenkins]# cat pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: jenkins-data6namespace: kube-devops
spec:accessModes:- ReadWriteManystorageClassName: "managed-nfs-storage6"resources:requests:storage: 5Gi

# 进入 jenkins 目录，安装 jenkins
kubectl apply -f manifests/# 查看是否运行成功
kubectl get po -n kube-devops# 查看 service 端口，通过浏览器访问
kubectl get svc -n kube-devops# 查看容器日志，获取默认密码
kubectl logs -f pod名称 -n kube-devops[root@kubeadm-master2 jenkins]# kubectl logs -f jenkins-7c558dd78b-bsp9x -n kube-devops
里面写了密码

jenkins yaml 文件

 [root@kubeadm-master2 manifests]# cat jenkins-configmap.yaml

安装插件

Build Authorization Token Root
Gitlab
SonarQube Scanner
代码质量审查工具在 Dashboard > 系统管理 > Configure System 下面配置 SonarQube serversName：sonarqube # 注意这个名字要在 Jenkinsfile 中用到
Server URL：http://sonarqube:9000
Server authentication token：创建 credentials 配置为从 sonarqube 中得到的 token进入系统管理 > 全局工具配置 > SonarQube Scanner > Add SonarQube Scanner
Name：sonarqube-scanner
自动安装：取消勾选
SONAR_RUNNER_HOME：/usr/local/sonar-scanner-cliNode and Label parameter
Kubernetesjenkins + k8s 环境配置进入 Dashboard > 系统管理 > 节点管理 > Configure Clouds 页面配置 k8s 集群
名称：kubernetes
点击 Kubernetes Cloud details 继续配置
Kubernetes 地址：如果 jenkins 是运行在 k8s 容器中，直接配置服务名即可https://kubernetes.default如果 jenkins 部署在外部，那么则不仅要配置外部访问 ip 以及 apiserver 的端口（6443），还需要配置服务证书
Jenkins 地址：如果部署在 k8s 集群内部：http://jenkins-service.kube-devops如果在外部：http://192.168.113.120:32479（换成你们自己的）配置完成后保存即可Config File ProviderGit Parameter

jenkins 配置k8s

https://kubernetes.default

添加标签

创建用户凭证

系统管理 > 安全 > Manage Credentials > System > 全局凭据（unrestricted） > Add Credentials范围：全局
用户名：root
密码：wolfcode
ID：gitlab-user-pass
