1. 拉取最新版jenkins镜像

#为了加快下载速度？？？好像也没加快啊
[root@localhost ~]# curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

docker version >= 1.12
{"registry-mirrors": ["http://f1361db2.m.daocloud.io"]}
Success.
You need to restart docker to take effect: sudo systemctl restart docker

systemctl restart docker

#查找可用镜像
[root@~]# docker search jenkins/jenkins

#运行jenkins

#解决方法

vim /etc/sysctl.conf

#添加如下代码：

net.ipv4.ip_forward=1

#重启network服务

systemctl restart network

#查看是否修改成功

sysctl net.ipv4.ip_forward

#注意文件夹权限 chmod -R a+x /home/develop/jenkins/

#先启动一个jenkins容器（不挂载数据卷）docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH 将jenkins文件拉出来，docker rm CONTAINER

#重新创建一个CONTAINER（挂载数据卷）

[root@localhost develop]# docker run --name jenkins -d -p 9003:8080 -p 9004:50000 -v /home/develop/jenkins/:/var/jenkins_home jenkins/jenkins:latest
