Docker 常用指令

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

docker创建一个容器

[root@localhost ~]# docker run -it -v /docker_test:/yufei  --name yufei_6 centos
# -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 -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                        PORTS               NAMES
724e7701f0d4        centos              "/bin/bash"         5 minutes ago       Up 5 minutes                                      yufei_6

# 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

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

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

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

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

[root@localhost ~]# docker stop yufei_5

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