运行容器

使用docker run 运行一个tomcat的容器

• --name yoyotomcat 容器重命名yoyotomcat
• -p 8090:8080 容器的8080端口映射到主机的8090端口
• -v ~/yoyo/tomcat/webapps/jenkins:/usr/local/tomcat/webapps/jenkins 容器的/usr/local/tomcat/webapps/jenkins 目录挂载到本机~/yoyo/tomcat/webapps/jenkins
• -d 挂后台运行

[root@bogon webapps]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8f99aa298cc8 tomcat "catalina.sh run" 59 seconds ago Up 57 seconds 0.0.0.0:8089->8080/tcp leslietomcat
4252c716b85d mysql:5.7 "docker-entrypoint.s…" 2 hours ago Up 2 hours 33060/tcp, 0.0.0.0:3309->3306/tcp lesliemysql
[root@bogon webapps]#

这样在浏览器输入http://主机ip:8090就能访问到tomcat首页了

 

 

部署war包

因为自身有Jenkins，所以启动的时候映射到安装目录

[root@bogon /]# docker run --name leslietomcat -p 8089:8080 -v /opt/shaobo/apache-tomcat-9.0.20/webapps:/usr/local/tomcat/webapps -d tomcat
