3.查看当前运行的容器

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d63526a50c3c centos "/bin/bash" 43 seconds ago Up 42 seconds centos2
4.列出所有的容器，包括历史运行的

Error response from daemon: You cannot remove a running container d63526a50c3ce8a5fbb3355751b494a251ce06ebff3e65e22690c020117f88a3. Stop the container before attempting removal or force remove
在运行的容器不能删除，或者强制删除 docker rm -f
[root@VM-0-9-centos /]
d63526a50c3c
7.启动容器
docker start 容器id
[root@VM-0-9-centos /]
dd8e964dc3c2
docker start 和docker run 的区别：
docker satat :重新启动一个关闭的容器
docker run ：根据镜像启动一个容器
8.停止容器
docker stop ??容器id
docker kill ???容器id
[root@VM-0-9-centos /]
e160eb260ebd
docker stop 和docker kill
两者都是关闭容器，
docker stop：允许其在一定时间（默认10s）内进行一些操作（例如资源回收），若这段时间内容器未停止，则发送SIGKILL信号强行杀死容器。
docker kill: 直接发送SIGKILL信号杀死容器
9.重启容器
docker restart 容器id
