前面已經對安裝Tomcat進行了詳解：docker入門學習（一）　　　

直接上代碼

//啟動一個Tomcat 命名為mytomcat
[root@localhost ~]# docker run -d  --name mytomcat -p 9999:8080 tomcat
cecb37db8134f1b1fe6d13c43b0b22d1832a9937b9d2bbfa9958eb180bd81eb6
//上傳war包到linux主機   我上傳到home文件夾下
[root@localhost ~]# cd /home
[root@localhost home]# ls
qrcode.war
[root@localhost 
 
~]# docker ps

//進入一個容器 sudo docker exec -it 容器id /bin/bash 
 

[root@localhost ~]# sudo docker exec -it cecb37db8134 /bin/bash
root@cecb37db8134:/usr/local/tomcat# ls
BUILDING.txt     LICENSE  README.md      RUNNING.txt  conf     lib   native-jni-lib  webapps
CONTRIBUTING.md  NOTICE   RELEASE-NOTES  bin          include  logs  temp            work
root@cecb37db8134:/usr/local/tomcat# 
//Ctrl+D 退出容器
root@cecb37db8134:/usr/local/tomcat# exit
//復制war到Tomcat的webapps目錄下
[root@localhost ~]# docker cp /home/qrcode.war cecb37db8134:/usr/local/tomcat/webapps
//重新進入容器 qrcode.war已經在webapps目錄下了
[root@localhost ~]# sudo docker exec -it cecb37db8134 /bin/bash
root@cecb37db8134:/usr/local/tomcat# ls
BUILDING.txt     LICENSE  README.md      RUNNING.txt  conf     lib   native-jni-lib  webapps

ROOT  docs  examples  host-manager  manager  qrcode  qrcode.war
root@cecb37db8134:/usr/local/tomcat# 

常用命令：

//通過鏡像產生一個容器
docker run -p port1:port2 containerName:tag
//啟動一個已有的容器
docker start containerID/containerName
//停止一個容器
docker stop containerID/containerName
//重啟一個容器
docker restart containerID/containerName
//與一個已經啟動的容器進行交互式操作
docker exec -i -t containnerID/containerName /bin/bash
//復制文件到容器中
docker cp src_path containerId:dest_path
