前面已经对安装Tomcat进行了详解：docker入门学习（一）
直接上代码
//启动一个Tomcat 命名为mytomcat [root@localhost ~]# docker run -d --name mytomcat -p 9999:8080 tomcat cecb37db8134f1b1fe6d13c43b0b22d1832a9937b9d2bbfa9958eb180bd81eb6 //上传war包到linux主机 我上传到home文件夹下 [root@localhost ~]# cd /home [root@localhost home]# ls qrcode.war [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES cecb37db8134 tomcat "catalina.sh run" 9 minutes ago Up 9 minutes 0.0.0.0:9999->8080/tcp mytomcat 1226f307b5ba tomcat "catalina.sh run" About an hour ago Up 28 minutes 0.0.0.0:8888->8080/tcp agitated_leavitt ec9d0d788590 mysql "docker-entrypoint.s…" 16 hours ago Up 16 hours 0.0.0.0:3306->3306/tcp, 33060/tcp mysql02 //进入一个容器 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 //复制war到Tomcat的webapps目录下 [root@localhost ~]# docker cp /home/qrcode.war cecb37db8134:/usr/local/tomcat/webapps //重新进入容器 qrcode.war已经在webapps目录下了 [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 CONTRIBUTING.md NOTICE RELEASE-NOTES bin include logs temp work root@cecb37db8134:/usr/local/tomcat# ls ./webapps/ ROOT docs examples host-manager manager qrcode qrcode.war root@cecb37db8134:/usr/local/tomcat#
常用命令：
//通过镜像产生一个容器 docker run -p port1:port2 containerName:tag //启动一个已有的容器 docker start containerID/containerName //停止一个容器 docker stop containerID/containerName //重启一个容器 docker restart containerID/containerName //与一个已经启动的容器进行交互式操作 docker exec -i -t containnerID/containerName /bin/bash //复制文件到容器中 docker cp src_path containerId:dest_path
访问结果：成功
