1、基本概念

　　Jenkins在DevOps工具链中是核心的流程管理中心，负责串联系统的构建流程、测试流程、镜像制作流程、部署流程等，在持续集成中常用到的工具如下：

　　Maven：源代码编译工具

　　RobotFramework：自动化测试工具

　　NewMan：接口自动化测试工具

　　SonarQube Scanner：源代码扫描工具

　　GitLab：代码仓库工具

　　Docker：镜像制作工具

　　kubectl：K8S工具

　　公司目前使用的流程是通过Redmine和GitLab中创建项目、开发提交代码、触发jenkins完成镜像构建并自动部署到k8s集群。

2、部署

[root@k8s-master01 jenkins]# git clone https://github.com/dotbalo/helm.git

[root@k8s-master01 ~]# cd helm/jenkins

[root@k8s-master01 jenkins]# helm install --name jenkins . --namespace public-service NAME: jenkins LAST DEPLOYED: Tue Dec 4 14:55:24 2018 NAMESPACE: public-service STATUS: DEPLOYED RESOURCES: ==> v1/Secret NAME AGE jenkins 0s ==> v1/ConfigMap jenkins 0s jenkins-tests 0s ==> v1/PersistentVolumeClaim jenkins 0s ==> v1/Service jenkins-agent 0s jenkins 0s ==> v1beta1/Deployment jenkins 0s ==> v1/Pod(related) NAME READY STATUS RESTARTS AGE jenkins-5b6c648956-zds2p  0/1    Pending  0 0s NOTES: 1. Get your 'admin' user password by running: printf $(kubectl get secret --namespace public-service jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo
2. Get the Jenkins URL to visit by running these commands in the same shell: export POD_NAME=$(kubectl get pods --namespace public-service -l "component=jenkins-master" -o jsonpath="{.items[0].metadata.name}") echo http://127.0.0.1:8080
  kubectl port-forward $POD_NAME 8080:8080

3. Login with the password from step 1 and the username: admin For more information on running Jenkins on Kubernetes, visit: https://cloud.google.com/solutions/jenkins-on-container-engine

　　创建ingress

[root@k8s-master01 jenkins]# kubectl create -f traefik-jenkins.yaml 
ingress.extensions/jenkins created

3、查看状态

[root@k8s-master01 ~]# kubectl get po,svc,ingress,pvc -n public-service | grep jenkins
pod/jenkins-5b6c648956-zds2p           1/1     Running   5          44h
service/glusterfs-dynamic-jenkins                  ClusterIP   10.111.100.114   <none>        1/TCP                       44h
service/jenkins                                    ClusterIP   10.107.215.94    <none>        8080/TCP                    44h
service/jenkins-agent                              ClusterIP   10.103.212.222   <none>        50000/TCP                   44h
ingress.extensions/jenkins   jenkins.xxx.net             80      3m26s
persistentvolumeclaim/jenkins                  Bound    pvc-953c3093-f791-11e8-9640-000c298bf023   20Gi       RWX            gluster-heketi-2   44h

4、访问测试

　　查看密码

[root@k8s-master01 ~]# kubectl get secret --namespace public-service jenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode
