Docker Tomcat镜像制作(3)

[root@localhost sysctl.d]# docker ps -a
CONTAINER ID        IMAGE              COMMAND            CREATED            STATUS                      PORTS                    NAMES
6a3c7c96df93        tomcat              "catalina.sh run"  22 seconds ago      Up 20 seconds              0.0.0.0:8080->8080/tcp    youthful_carson
[root@localhost sysctl.d]# cd

6.进入已经运行的容器

docker exec -it containerID /bin/bash 这个命令exit退出，ok容器还在运行
docker attach id 刚方法进入之后，exit退出就会导致容器stop

[root@localhost sysctl.d]# docker ps -a

无法使用vi vim

apt-get update，这个命令的作用是：同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。 

等更新完毕以后再敲命令：apt-get install vi命令即可
