# 通过id或名称来操作 $ docker start 0d320f497f02 0d320f497f02 - 进入容器(exec与attach的区别)
exec是执行命令的意思，就是在当前宿主机上执行容器中的命令，通过-it的参数可以输入与输出，执行bash命令就是其中的一种，这个命令会打开一个终端，此时宿主主机当前的终端被容器内的终端所覆盖，所以的操作都会被容器接管-
attach：Attach local standard input, output, and error streams to a running container，意思是跟踪容器内的输入与输出，也就是说，如果多个终端同时attach到一个容器，大家的可以看到相同的界面，我能看到你输入的，你也能看到我输出的，同步。# 通过Docker执行脚本的方式打开容器内的终端 $ docker exec -it 582eb515c4ee bash [root@582eb515c4ee /]# # 通过attach命令进入容器的控制台 $ docker attach 582eb515c4ee [root@582eb515c4ee /]#
