30-案列4：构建Jenkins应用镜像

1.进入目录

[root@docker01 runtime]# cd /data/dockerfile/app/
[root@docker01 app]# mkdir jenkins
[root@docker01 app]# cd jenkins

 2.编写dockerfile文件

[root@docker01 jenkins ]# vim Dockerfile

#Base Image
FROM system/centos:v4

#Maintainer
MAINTAINER xiao@qq.com

ADD jenkins.war /usr/local/tomcat/webapps/

#Outside port
EXPOSE 22 8080

CMD ["/usr/bin/supervisord","-c","/etc/supervisord.conf"]

 3.构建jenkin镜像

[root@docker01 jenkins]# docker build -t app/jenkins .
