连接容器的 shell

docker container run -it 创建一个容器并进入交互式模式

➜  ~ docker container run -it busybox sh
/ #
/ #
/ # ls
bin   dev   etc   home  proc  root  sys   tmp   usr   var
/ # ps
PID   USER     TIME  COMMAND
    1 root      0:00 sh
    8 root      0:00 ps
/ # exit

docker container exec -it 在一个已经运行的容器里执行一个额外的command

➜  ~ docker container run -d nginx
