ker入門到kubernetes實戰(zhàn)全集課件第18節(jié)-machine構建容器

1、docker-machineDocker Machine 是一個簡化安裝 Docker 環(huán)境的工具。市場上主流 Linux 系統(tǒng)版本很多，使用 Machine 工具就簡單很多，一兩條命令即可在主流 Linux 系統(tǒng)上安裝 Docker 環(huán)境，用戶不用考慮什么操作系統(tǒng)。Docker Machine 還具備 Docker 工具管理虛擬化技術，Generic驅(qū)動默認管理 LXC 容器技術。Docker Machine 支持多種后端驅(qū)動，包括虛擬機、本目前支持的驅(qū)動：amazonec2 azure digitalocean exoscalegeneric機和云等。Docker Machinenone

2、openstack rackspace softlayer virtualboxvmwarevcloudairvmwarevsphere這使得 Docker 可以再 windows,linux 上面安裝：安裝 Docker-machine:$ curl -L/docker/machine/releases/download/v0.7.0/docker-machine-uname -s-uname -m /usr/local/bin/docker-machine/usr/local/bin/docker-machine&od +x#網(wǎng)上很多文檔，可以相應安裝，我這里用的版本比較低：rootmas

3、ter bin# docker-machine -vdocker-machinever0.4.0 (9d0dc7a)基于本地安裝一個基于 vitrualbox 啟動的 Docker:rootmaster src# yum install VirtualBox-5.1-5.1.20_114628_el7-1.x86_64.rpm1、創(chuàng)建 Docker 環(huán)境：rootmaster # docker-machine create -d virtualbox -engine-registry-mirrordocke-webCreating VirtualBox VM.CreatingStarting
