Master节点的安装
拉取镜像最新的jenkins镜像：1
docker pull jenkins/jenkins
使用docker运行jenkins：1
docker run -idt -v /home/ap/ci/jenkins:/home/jenkins -v /home/ap/ci/jenkins_home:/home/data -p 8002:8080 -p 50000:50000 jenkins
其中将8080端口映射到主机的8002端口，50000端口为jnlp端口，slave连接master时使用，不建议映射其它端口
修改文件的用户和组：1

11chown [-R] 账号名称 文件或目录
chown [-R] 账号名称:用户组名称 文件或目录
参数：
-R : 进行递归( recursive )的持续更改，即连同子目录下的所有文件、目录
都更新成为这个用户组。常常用在更改某一目录的情况。
chgrp [-R] 用户组名称 dirname/filename ...
例:
chown -R ci:ci testfile
chgrp ci testfile
docker运行jenkins的命令改为：1
docker run -idt --privileged=true -v /home/ap/ci/jenkins/jenkins:/home/jenkins:rw -v /home/ap/ci/jenkins/data:/home/data:rw -v /home/ap/ci/jenkins/var/jenkins_home:/var/jenkins_home:rw -p 8002:8080 -p 50000:50000 jenkins
加入邮箱参数：1
docker run -idt --privileged=true -v /home/ap/ci/jenkins/jenkins:/home/jenkins:rw -v /home/ap/ci/jenkins/data:/home/data:rw -v /home/ap/ci/jenkins/var/jenkins_home:/var/jenkins_home:rw -p 8002:8080 -p 50000:50000 --env JAVA_OPTS=-Dmail.smtp.starttls.enable=true jenkins
Slave节点的安装
在jenkins的控制页面上新建节点slave1，记下secret
使用docker运行jenkins：1
docker run jenkins/jnlp-slave -url http://10.128.13.24:8002 -workDir=/home/jenkins/agent 0970d2705317754f3a5ba366a67a891733668e1503c0a9c043a6883bad349d8c slave1
其中-url后为jenkins的地址
安装过程中出现的问题
网上教程中slave连接master用的是jnlp端口，即slave启动命令：1
docker run jenkins/jnlp-slave -url http://10.128.13.24:50000 -workDir=/home/jenkins/agent 0970d2705317754f3a5ba366a67a891733668e1503c0a9c043a6883bad349d8c slave1

jnlp-slave中默认连接maste节点的50000端口，将master节点启动的jnlp端口设为50000，程序正常
