四、基于java包方式运行jenkins应用

基于java命令，运行java war包或jar包，本次以jenkins.war 包部署方式为例，且要求jenkins的数据保存至外部存
储(NFS或者PVC)，其他java应用看实际需求是否需要将数据保存至外部存储。



[root@localhost7C jenkins]# ll
-rwxr-xr-x 1 root root      226 4月   3 15:26 build-command.sh
-rw-r--r-- 1 root root      266 4月   3 15:26 Dockerfile

-rwxr-xr-x 1 root root      152 4月   9 2020 run_jenkins.sh


[root@localhost7C jenkins]# cat run_jenkins.sh 
#!/bin/bash
cd /apps/jenkins && java -server -Xms1024m -Xmx1024m -Xss512k -jar jenkins-2.222.1.war --webroot=/apps/jenkins/jenkins-data --httpPort=8080


#镜像参考https://www.cnblogs.com/Yuanbangchen/p/17264215.html
[root@localhost7C jenkins]# cat Dockerfile 
#Jenkins Version 2.190.1

MAINTAINER zhangshijie zhangshijie@magedu.net
RUN mkdir /apps/jenkins/ -p
ADD jenkins-2.222.1.war /apps/jenkins/
ADD run_jenkins.sh /usr/bin/
EXPOSE 8080 
CMD ["/usr/bin/run_jenkins.sh"]

[root@localhost7C jenkins]# cat build-command.sh 
#!/bin/bash
docker build -t  harbor.zzhz.com/linux39/jenkins:v2.222.1 .
echo "镜像制作完成，即将上传至Harbor服务器"
sleep 1
docker push harbor.zzhz.com/linux39/jenkins:v2.222.1
echo "镜像上传完成"
sleep 1


[root@localhost7C jenkins]# chmod  +x  *.sh
[root@localhost7C jenkins]# ./build-command.sh 




2.安装nfs服务器，基于PV和PVC作为后端存储
#需要两个PVC，一个保存jenkins的数据，一个保存.jenkins的数据。
[root@localhost7B ]# cat  /etc/exports
/data/k8sdata  *(rw,no_root_squash)


[root@localhost7B ~]# mkdir /data/k8sdata/magedu/jenkins-data
[root@localhost7B ~]# mkdir /data/k8sdata/magedu/jenkins-root-data

[root@localhost7B ]# systemctl  restart  nfs-server.service


#写数据测试
mount -t nfs 192.168.80.110:/data/k8sdata/magedu/redis-datadir-1   /mnt
