Summary of Common Commands for docker

I won't mention the advantages of a specific docker, but here are some common docker commands:

1. Start, stop, restart of docker

[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 creates a container

  
[root@localhost ~]# docker run -it -v /docker_test:/yufei  --name yufei_6 centos
[root@724e7701f0d4 /]# 
-i: Allows us to interact with (STDIN) in containers
-t: Specify a pseudo terminal or terminal in a new container
-v: is hanging in the hosting directory, /docker_The test is the hosting directory, /yufei is the directory of the current docker container, and the hosting directory must be absolute.
--name: is to give the container a name, omitted, docker will randomly produce a name if omitted

3. List of containers started by docker

[root@localhost ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

f9097691663e        centos              "/bin/bash"         5 minutes ago       Up 5 minutes                            yufei_5
[root@localhost ~]#

[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
