ker入門到kubernetes實(shí)戰(zhàn)全集課件第18節(jié)-machine構(gòu)建容器

1、docker-machineDocker Machine 是一個(gè)簡(jiǎn)化安裝 Docker 環(huán)境的工具。市場(chǎng)上主流 Linux 系統(tǒng)版本很多，使用 Machine 工具就簡(jiǎn)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(shù)，Generic驅(qū)動(dòng)默認(rèn)管理 LXC 容器技術(shù)。Docker Machine 支持多種后端驅(qū)動(dòng)，包括虛擬機(jī)、本目前支持的驅(qū)動(dòng)：amazonec2 azure digitalocean exoscalegeneric機(jī)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(yīng)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(gè)基于 vitrualbox 啟動(dòng)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
