实战交付一套dubbo微服务到k8s集群(2)之Jenkins部署
Jenkins官网：https://www.jenkins.io/zh/
Jenkins 2.190.3 镜像地址：docker pull jenkins/jenkins:2.190.3
1.下载Jenkins镜像
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# docker pull jenkins/jenkins:2.190.3
2.对jenkins打标签并上传至私有仓库
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# docker images | grep jenkins
[root@mfyxw50 ~]# docker tag 22b8b9a84dbe harbor.od.com/public/jenkins:v2.190.3
[root@mfyxw50 ~]# docker login harbor.od.com
[root@mfyxw50 ~]# docker push harbor.od.com/public/jenkins:v2.190.3
3.自定义Dockerfile文件
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# mkdir -p /data/dockerfile/jenkins
[root@mfyxw50 ~]# cat > /data/dockerfile/jenkins/Dockerfile << EOF
FROM harbor.od.com/public/jenkins:v2.190.3
USER root
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
echo 'Asia/Shanghai' > /etc/timezone
ADD id_rsa /root/.ssh/id_rsa
ADD config.json /root/.docker/config.json
ADD get-docker.sh /get-docker.sh
RUN echo " StrictHostKeyChecking no" >> /etc/ssh/ssh_config &&\
/get-docker.sh
EOF
这个Dockerfile里我们主要做了以下几件事
- 设置容器用户为root
- 设置容器内的时区
- 将ssh私钥加入（使用git拉代码时要用到，配对的公钥应配置在gitlab中）
- 加入了登录自建harbor仓库的config文件
- 修改了ssh客户端的
- 安装一个docker的客户端
4.生成ssh密钥对
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# ssh-keygen -t rsa -b 2048 -C "mfyxw@qq.com" -N "" -f /root/.ssh/id_rsa
4.将dockerfile文件需要的文件复制到jenkins目录
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# cd /data/dockerfile/jenkins/
[root@mfyxw50 jenkins]# cp /root/.ssh/id_rsa .
[root@mfyxw50 jenkins]# cp /root/.docker/config.json .
[root@mfyxw50 jenkins]# curl -fsSL get.docker.com -o get-docker.sh
[root@mfyxw50 jenkins]# chmod +x get-docker.sh

5.在harbor私有仓库中创建存放jenkin的私有镜像
6.制作自定义镜像
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# cd /data/dockerfile/jenkins/
[root@mfyxw50 jenkins]# docker build . -t harbor.od.com/infra/jenkins:v2.190.3
7.将infra/jenkins的镜像推送到私有仓库
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# docker images | grep jenkins
[root@mfyxw50 ~]# docker login harbor.od.com
[root@mfyxw50 ~]# docker push harbor.od.com/infra/jenkins:v2.190.3
8.查看仓库中infra是否已经上传了jenkins
9.测试是否能正常登录
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 jenkins]# docker run --rm harbor.od.com/infra/jenkins:v2.190.3 ssh -i /root/.ssh/id_rsa -T XXX@gitee.com
10.创建保存jenkins目录
在运维主机(mfyxw50.mfyxw.com)上操作
[root@mfyxw50 ~]# mkdir -p /data/k8s-yaml/jenkins
[root@mfyxw50 ~]# mkdir -p /data/nfs-volume/jenkins_home
[root@mfyxw50 ~]# cd /data/k8s-yaml/jenkins/
11.创建jenkins资源配置清单
在运维主机(mfyxw50.mfyxw.com)上操作

12.安装nfs服务
在运维节点(mfyxw30.mfyxw.com和mfyxw40.mfyxw.com)作为NFS客户端和运维主机(mfyxw50.mfyxw.com)作为NFS服务端同，分别执行
~]# yum -y install nfs-utils
在运维主机(mfyxw50.mfyxw.com)上执行如下操作
[root@mfyxw50 ~]# cat > /etc/exports << EOF
/data/nfs-volume 192.168.80.0/24(rw,no_root_squash)
EOF
创建nfs共享目录
[root@mfyxw50 ~]# mkdir -p /data/nfs-volume
启动NFS服务
[root@mfyxw50 ~]# systemctl start nfs && systemctl enable nfs
13.为拉私有仓库私有镜像创建一个secret
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)上任意一台执行
[root@mfyxw30 ~]# kubectl create secret docker-registry harbor --docker-server=harbor.od.com --docker-username=admin --docker-password=Harbor12345 -n infra
[root@mfyxw30 ~]# kubectl get secret -n infra
14.应用Jenkins资源配置清单
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
在应用资源配置清单 要先创建一个infra名称空间
[root@mfyxw30 ~]# kubectl create ns infra
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/jenkins/Deployment.yaml
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/jenkins/Service.yaml
[root@mfyxw30 ~]# kubectl apply -f http://k8s-yaml.od.com/jenkins/Ingress.yaml
15.查询pod，svc，ingress是否成功
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
备注，可能jenkins的pod的名称有不一致，但不影响整个教程
[root@mfyxw30 ~]# kubectl get pod -n infra
[root@mfyxw30 ~]# kubectl get svc -n infra
[root@mfyxw30 ~]# kubectl get ingress -n infra
16.添加解析域名jenkins.od.com
在DNS服务器(mfyxw10.mfyxw.com)上操作
[root@mfyxw10 ~]# cat > /var/named/od.com.zone << EOF
\$ORIGIN od.com.
\$TTL 600 ; 10 minutes

重启DNS服务器并尝试解析域名
[root@mfyxw10 ~]# systemctl restart named
[root@mfyxw10 ~]# dig -t A jenkins.od.com @192.168.80.10 +short
17.在浏览器中访问jenkins
18.查看jenkins的登录密码
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
查看jenkins运行在哪个node节点上
[root@mfyxw30 ~]# kubectl get pod -o wide -n infra
查询出来jenkins是运行在mfyxw40.mfyxw.com主机上，进入到/data/kubelet/pods/d4a68480-78ec-463d-b25e-d9caa8714219/volumes/kubernetes.io~nfs/data/secrets目录查看initialAdminPassword文件可以得到登录jenkins的密码
19.登录jenkins后操作及设置
成功安装了Blue Ocean插件
20.解决下载插件出错问题
如上图所示，就是在下载插件的时候会出现Failure，建议更换为国内源
国内源地址：https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
解决方法：
更换了源，再次去搜索并安装插件即可
可以进入到运维主机(mfyxw50.mfyxw.com)的/data/nfs-volume/jenkins_home/plugins目录下，可以看到下载的插件的软件都放在此目录中
21.通过查看日志判断jenkins是否完全启动
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
[root@mfyxw30 ~]# kubectl logs jenkins-b99776c69-jrvwn -n infra
22.验证jenkins是否可用
查看jenkins运行在哪台node节点上
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
[root@mfyxw30 ~]# kubectl get pod -n infra -o wide
在mfyxw40.mfyxw.com主机上执行
[root@mfyxw40 ~]# docker ps -a | grep jenkins
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
在jenkins容器中，验证jenkins容器是否以root身份运行及时区是否为东八区
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash #进入到jenkins容器
root@jenkins-b99776c69-p6skp:/# whoami #查看jenkins是否以root身份运行
root@jenkins-b99776c69-p6skp:/# date #查看jenkins的时区是否为东八区
在jenkins容器中，验证是否连接宿主机的docker的引擎
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
root@jenkins-b99776c69-p6skp:/# docker ps -a
在mfyxw40.mfyxw.com宿主机上查询所有的容器运行情况，是否与进入到jenkins容器里查询到的一致
[root@mfyxw40 ~]# docker ps -a
在jenkins容器中，验证是否可以登录到harbor仓库
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
root@jenkins-b99776c69-p6skp:/# docker login harbor.od.com
root@jenkins-b99776c69-p6skp:/# cat /root/.docker/config.json
在jenkins容器中，验证是否可以登录到gitee仓库
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
root@jenkins-b99776c69-p6skp:/# ssh -i /root/.ssh/id_rsa -T xxx@gitee.com
