╭─wil-xz in ~                                                                                                                                    12:15:44
╰─٩(ŏ﹏ŏ、)۶  service docker start 
Redirecting to /bin/systemctl start docker.service

2. 查看当前docker的所有镜像。docker images

╭─wil-xz in ~                                                                                                                                    12:15:44
╰─٩(ŏ﹏ŏ、)۶  docker images
REPOSITORY                                      TAG                 IMAGE ID            CREATED             SIZE

3. 查找某个服务环境的镜像。docker search php

╭─wil-xz in ~                                                                                                                                    12:16:31
╰─(ง๑ •̀_•́)ง  docker search php

4. 拉取镜像。docker pull php

╭─wil-xz in ~                                                                                                                                    12:17:57
╰─o(≧口≦)o  docker pull php

Status: Image is up to date for php:latest

5. 运行容器。docker run -tid --name container_name php

╭─wil-xz in ~                                                                                                                                    12:18:08
╰─ε=ε=ヾ(;ﾟдﾟ)/  docker run -tid --name php_c php
c77ba90444b478444bcb7dc27205c7980bbe196b101fb08c3c404f2b813e156e

6. 查看容器。docker ps 或 docker ps -a，docker ps 查看正在运行的容器，docker ps -a查看所有容器即包括停止的容器跟启动失败的容器。

╭─wil-xz in ~                                                                                                                                    12:18:54
╰─╰(*°▽°*)╯  docker ps

c77ba90444b4        php                                                 "docker-php-entrypoi…"   13 seconds ago      Up 20 seconds           

7. 查看容器报错日志。docker logs 容器名，假如容器没有启动成功，即，docker run后发现docker ps没有看到正在运行的容器，可以通过此命令查看报错信息。

╭─wil-xz in ~                                                                                                                                    12:20:30
╰─(*´･д･)?  docker logs cdbmaster

8. 查看容器环境。docker inspect 容器名

9. 查看容器内运行的进程。docker top 容器名

╭─wil-xz in ~                                                                                                                                    12:21:12
╰─(ﾟ3ﾟ)～♪  docker top php_c
PID                 USER                TIME                COMMAND
28858               root                0:00                php -a

10. 查看容器绑定端口。docker port 容器名

╭─wil-xz in ~                                                                                                                                    12:22:57
╰─o(≧口≦)o  docker port cmysqlproxy
4040/tcp -> 0.0.0.0:4040

11. 进入容器。 docker exec -it 容器名 bash

╭─wil-xz in ~                                                                                                                                    12:22:58
╰─ヽ(*。>Д<)o゜  docker exec -it php_c bash
root@c77ba90444b4:/# 

12. 删除容器。docker rm 容器名。删除容器前必须先运行 docker stop 容器名，停止容器。

╭─wil-xz in ~                                                                                                                                    12:23:53
╰─ヾ(;ﾟ;Д;ﾟ;)ﾉﾞ  docker stop php_c
php_c

╭─wil-xz in ~                                                                                                                                    12:24:11
╰─ヾ(;ﾟ;Д;ﾟ;)ﾉﾞ  docker rm php_c
php_c

13. 删除所有容器。docker rm $(docker ps -a -q)。前提必须停止所有容器，即运行docker stop $(docker ps -a -q)。

╭─wil-xz in ~                                                                                                                                    12:24:22
╰─٩(ŏ﹏ŏ、)۶  docker rm $(docker ps -a -q)

14. 删除镜像。docker rmi 镜像名

╭─wil-xz in ~                                                                                                                                    12:25:33
