Docker-Compose 我的项目是 Docker 官网的开源我的项目，负责实现对 Docker 容器集群的疾速编排。是 harbor 的默认容器编排工具。
- docker 命令能够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：

同理，docker images 和 docker-compose images 命令的区别也相似。
- 前者能够看到全副镜像。
后者只能看到部署 harbor 时的那些镜像。
