ker入门到kubernetes实战全集课件第18节-machine构建容器

1、docker-machineDocker Machine 是一个简化安装 Docker 环境的工具。市场上主流 Linux 系统版本很多，使用 Machine 工具就简单很多，一两条命令即可在主流 Linux 系统上安装 Docker 环境，用户不用考虑什么操作系统。Docker Machine 还具备 Docker 工具管理虚拟化技术，Generic驱动默认管理 LXC 容器技术。Docker Machine 支持多种后端驱动，包括虚拟机、本目前支持的驱动：amazonec2 azure digitalocean exoscalegeneric机和云等。Docker Machinenone
