k8s安装直接跳过，用Kubeadm安装也比较简单node
安装和配置 NFS
NFS简介
NFS（Network File System），它最大的功能就是能够经过网络，让不一样的机器、不一样的操做系统能够
共享彼此的文件。咱们能够利用NFS共享Jenkins运行的配置文件、Maven的仓库依赖文件等
NFS安装直接跳过，以前博客也写过git
[root@k8s-master ~]# cat /etc/exports /opt/nfs/jenkins *(rw,no_root_squash) /opt/nfs/maven *(rw,no_root_squash) [root@k8s-master ~]# [root@k8s-master ~]# showmount -e 192.168.1.114 Export list for 192.168.1.114: /opt/nfs/maven * /opt/nfs/jenkins * [root@k8s-master ~]#
Kubernetes安装Jenkins-Master
建立NFS client provisioner
nfs-client-provisioner 是一个Kubernetes的简易NFS的外部provisioner，自己不提供NFS，须要现有
的NFS服务器提供存储。
1）上传nfs-client-provisioner构建文件docker
[root@k8s-master ~]# cd /wgr/ [root@k8s-master wgr]# ll total 0 drwxr-xr-x 5 root root 67 Jun 2 13:20 jenkins [root@k8s-master wgr]# cd jenkins/ [root@k8s-master jenkins]# ll total 0 drwxr-xr-x 2 root root 94 Jun 2 12:41 jenkins-master drwxr-xr-x 2 root root 81 Jun 2 13:20 jenkins-slave drwxr-xr-x 2 root root 64 Jun 2 12:19 nfs-client [root@k8s-master jenkins]# cd nfs-client/ [root@k8s-master nfs-client]# ll total 12 -rw-r--r-- 1 root root 225 Jun 2 12:19 class.yaml -rw-r--r-- 1 root root 983 Jun 2 12:19 deployment.yaml -rw-r--r-- 1 root root 1526 Jun 2 12:19 rbac.yaml [root@k8s-master nfs-client]#
执行apache
kubectl create -f .
安装Jenkins-Master
1）上传Jenkins-Master构建文件json
2）建立kube-ops的namespace
由于咱们把Jenkins-Master的pod放到kube-ops下数组
kubectl create namespace kube-ops
3）构建Jenkins-Master的pod资源服务器
kubectl create -f .
4）查看pod是否建立成功 网络
查看分配的端口maven
Jenkins与Kubernetes整合
安装Kubernetes插件
系统管理->插件管理->可选插件ide
实现Jenkins与Kubernetes整合
系统管理->系统配置->云->新建云->Kubernetes
kubernetes地址采用了kube的服务器发现： https://kubernetes.default.svc.cluster.local
namespace填kube-ops，而后点击Test Connection，若是出现 Connection test successful 的提
示信息证实 Jenkins 已经能够和 Kubernetes 系统正常通讯
Jenkins URL 地址： http://jenkins.kube-ops.svc.cluster.local:8080
构建Jenkins-Slave自定义镜像
Jenkins-Master在构建Job的时候，Kubernetes会建立Jenkins-Slave的Pod来完成Job的构建。咱们选择
运行Jenkins-Slave的镜像为官方推荐镜像：jenkins/jnlp-slave:latest，可是这个镜像里面并无Maven
环境，为了方便使用，咱们须要自定义一个新的镜像：
准备材料：
Dockerfile以下:
FROM jenkins/jnlp-slave:latest MAINTAINER itcast # 切换到 root 帐户进行操做 USER root # 安装 maven COPY apache-maven-3.6.2-bin.tar.gz . RUN tar -zxf apache-maven-3.6.2-bin.tar.gz && \ mv apache-maven-3.6.2 /usr/local && \ rm -f apache-maven-3.6.2-bin.tar.gz && \ ln -s /usr/local/apache-maven-3.6.2/bin/mvn /usr/bin/mvn && \ ln -s /usr/local/apache-maven-3.6.2 /usr/local/apache-maven && \ mkdir -p /usr/local/apache-maven/repo COPY settings.xml /usr/local/apache-maven/conf/settings.xml USER jenkins
构建出一个新镜像： jenkins-slave-maven:latest
然把镜像上传到Harbor的公共库library中
生成凭证
[root@k8s-master maven]# kubectl create secret docker-registry registry-auth-secret --docker-server=192.168.1.120:8001 --docker-username=admin --docker-password=Harbor12345 --docker-email=dalianpai@163.com secret/registry-auth-secret created [root@k8s-master maven]# kubectl get secret NAME TYPE DATA AGE default-token-d4gmj kubernetes.io/service-account-token 3 10d nfs-client-provisioner-token-rqxj2 kubernetes.io/service-account-token 3 21h qingcloud kubernetes.io/dockerconfigjson 1 10d registry-auth-secret kubernetes.io/dockerconfigjson 1 12s

//编译，构建本地镜像
sh "mvn -f ${currentProjectName} clean package dockerfile:build"
