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

   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
9jni0dNNY9

  登录:admin/9jni0dNNY9

 

 

5、配置LDAP登录

  系统管理 -- 插件管理

  建立openLDAP组织架构如下

  ou=People对应的用户的组为ou=jenkins,ou=Groups里面的组

  系统管理 -- 全局安全配置

  配置如下

  配置完LDAP登陆以后,本地认证就会失效,所以提前配置好权限也可,上述权限按需修改。

  另外,本人对openLDAP filter语法不太熟,配置邮箱登录的时候无法获取对应的组,所以采用了uid登录,如有openLDAP大神还请指教。

  验证权限,登录jenkins-dev组的用户

  无法管理jenkins
