Docker 入门私人笔记（十六）回顾和总结3 - 命令 docker 和 docker-compose 的区别

Docker-Compose 项目是 Docker 官方的开源项目，负责实现对 Docker 容器集群的快速编排。是 harbor 的默认容器编排工具。

• docker 命令可以查看和操作宿主机中所有正在运行的容器；

• docker-compose 只能看到和操作由它负责管理的正在运行的容器（本次实操中能看到组成 harbor 服务的所有容器。此时还并未向 harbor 提交任何镜像），而看不到也不能操作用 docker 命令部署的容器。例如：后者看不到 mydocker 这个容器：

  [root@k8s-master /data]# docker start mydocker
  mydocker
  [root@k8s-master /data]# 
  [root@k8s-master /data]# docker ps

同理，docker images 和 docker-compose images 命令的区别也类似。

• 前者可以看到全部镜像。

• 后者只能看到部署 harbor 时的那些镜像。
