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 will3369/php5.6 latest 838e8980cb1d 2 days ago 506MB

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 CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 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 2018-10-31 08:38:20 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

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 ╰─(ﾟ3ﾟ)～♪ docker rmi php Untagged: php:latest Untagged: php@sha256:417dd4c0f12e5cd3f284b48b5ea6b13d38eda8eacc9008774637df389590d6da Deleted: sha256:df1b7c730f916447514631a9f9847fc39d6f55cc2525693700623939aa946b78
