七、Docker 容器

在上一章节中我们使用 docker run 命令运行了一个 Hello World 开启了 Docker 容器的使用

每次遇到这种新的技术,我都有一个待解问题,到底有多少命令,我要怎么使用它们

那么,Docker 中到底有多少命令呢?

docker 命令

上一章节中我们所使用的所有命令都以 docker 开头,那如果直接运行 docker 命令会怎么样呢?

答案就是列出 Docker 所支持的所有命令

[root@localhost ~]# docker

很长的命令列表,不过只要关注最后一行就好了

大概意思是说可以通过命令 docker command –help 更深入的了解指定的 Docker 命令使用方法

例如我们要查看 docker stats 指令的具体使用方法

可以输入如下的命令

[root@localhost ~]# docker stats --help
