1、docker的启动、停止、重启
[root@localhost ~]# service docker restart
Redirecting to /bin/systemctl restart docker.service
[root@localhost ~]# service docker stop
Redirecting to /bin/systemctl stop docker.service
[root@localhost ~]# service docker start
Redirecting to /bin/systemctl start docker.service
2、docker创建一个容器
[root@localhost ~]# docker run -it -v /docker_test:/yufei --name yufei_6 centos
[root@724e7701f0d4 /]#
-i：允许我们对容器内的 (STDIN) 进行交互
-t：在新容器内指定一个伪终端或终端
-v：是挂在宿机目录， /docker_test是宿机目录，/yufei是当前docker容器的目录，宿机目录必须是绝对的。
--name：是给容器起一个名字，可省略，省略的话docker会随机产生一个名字
3、docker启动的容器列表
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
724e7701f0d4 centos "/bin/bash" 4 minutes ago Up 4 minutes yufei_6
f9097691663e centos "/bin/bash" 5 minutes ago Up 5 minutes yufei_5
[root@localhost ~]#
3、查看docker创建的所有容器
[root@localhost ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
724e7701f0d4 centos "/bin/bash" 5 minutes ago Up 5 minutes yufei_6
f9097691663e centos "/bin/bash" 6 minutes ago Up 6 minutes yufei_5
e59a540fb979 centos "/bin/base" 6 minutes ago Created yufei_4
ff49dfedea4f centos "/bin/bash" 2 hours ago Exited (137) 10 minutes ago yufei_03
d2cc70abb5a5 centos "/bin/bash" 2 hours ago Exited (127) 2 hours ago yufei_02
2d48fc5b7c17 centos "/bin/bash" 2 hours ago Exited (127) 2 hours ago yufei_01
[root@localhost ~]#
docker ps 默认列表是正在启动的容器 -a是显示所有创建的容器
4、启动、停止、重启某个docker 容器
[root@localhost ~]# docker start yufei_01
yufei_01
[root@localhost ~]# docker stop yufei_01
yufei_01
[root@localhost ~]# docker restart yufei_01
yufei_01
[root@localhost ~]#
5、查看指定容器的日志记录
[root@localhost ~]# docker logs -f yufei_01
[root@2d48fc5b7c17 /]# ls
anaconda-post.log bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
[root@2d48fc5b7c17 /]# exit
exit
[root@2d48fc5b7c17 /]# ls
anaconda-post.log bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]#
[root@2d48fc5b7c17 /]# cd /
[root@2d48fc5b7c17 /]# ls
anaconda-post.log bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
[root@2d48fc5b7c17 /]# mkdir yufei
[root@2d48fc5b7c17 /]# ls
anaconda-post.log bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var yufei
[root@2d48fc5b7c17 /]# cd yufei
[root@2d48fc5b7c17 yufei]# ls
yufei
[root@2d48fc5b7c17 yufei]# cd yufei
[root@2d48fc5b7c17 yufei]# ls
application
[root@2d48fc5b7c17 yufei]# cd ../../
[root@2d48fc5b7c17 /]# rm -rf yufei
[root@2d48fc5b7c17 /]# eixt
bash: eixt: command not found
[root@2d48fc5b7c17 /]# exit
exit
[root@2d48fc5b7c17 /]#
上面红色部分是日志命令部分。
6、删除某个容器，若正在运行，需要先停止
[root@localhost ~]# docker rm yufei_01
Error response from daemon: You cannot remove a running container 2d48fc5b7c17b01e6247cbc012013306faf1e54f24651d5e16d6db4e15f92d33. Stop the container before attempting removal or use -f
[root@localhost ~]# docker stop yufei_01
yufei_01
[root@localhost ~]# docker rm yufei_01
yufei_01
[root@localhost ~]#
7、删除所有容器
[root@localhost ~]# docker rm $(docker ps -a -q)
Error response from daemon: You cannot remove a running container 724e7701f0d4a830167e21f75b470235a0e408fd6cc2913403426e96f69cba11. Stop the container before attempting removal or use -f

[root@localhost ~]#
[root@localhost ~]#
[root@localhost ~]# docker stop yufei_6
yufei_6
[root@localhost ~]# docker stop yufei_5
yufei_5
[root@localhost ~]# docker rm $(docker ps -a -q)
