docker-machine安装与使用

安装

window安装

安装教程 https://www.runoob.com/docker/windows-docker-install.html

win7、win8、win10家庭版 使用 docker-toolbox 安装
下载地址：http://mirrors.aliyun.com/docker-toolbox/windows/docker-toolbox/

win10专业版安装 Toolbox 下载地址： https://www.docker.com/get-docker

win10家庭版

docker120和docker121 是docker-machine创建的docker环境
docker122为已有主机上已经安装的docker加入到docker-machine中
defalut 为win10家庭版默认运行的虚拟机docker主机

linux安装

官方教程 https://docs.docker.com/machine/install-machine/

卸载

linux

Remove the executable: rm $(which docker-machine)

rm $(which docker-machine)

删除1或多台机器
docker-machine rm

$ docker-machine rm --help
Usage: docker-machine rm [OPTIONS] [arg...]

删除所有docker machine
To remove all machines: docker-machine rm -f $(docker-machine ls -q) (you might need to use -force on Windows).

docker-machine rm -f $(docker-machine ls -q)

使用

创建docker主机

使用远程已有虚拟机

测试创建120

1. 设置免密登录目标主机192.168.72.120，docker-machine已经生产相关ssh签名

   ssh-copy-id [email protected]

2. 安装docker machine

安装时需要一些时间下载包

docker-machine create --driver generic --generic-ip-address=192.168.72.120 docker120

3. 避免 docker-machine ls 被防火墙防御无法正常访问docker tcp端口
   方式一：关闭并停止防火墙,避免 docker-machine，这里我直接关闭防火墙

systemctl stop firewalld; systemctl disable firewalld

方式二：添加放行的docker 2376端口

直接使用虚拟机api创建machine

docker-machine命令
在virtualbox下虚拟机下安装docker-machine

$ docker-machine create --driver virtualbox --engine-registry-mirror https://1rqn7spi.mirror.aliyuncs.com dockerA1

创建成功例子如下：

$ docker-machine create --driver virtualbox --engine-registry-mirror https://1rqn7spi.mirror.aliyuncs.com dockerA1

$ docker-machine.exe ip dockerA1

docker122提示的信息时因为 主机中的docker为自己手动安装，为配置 tls 相关证书，不是使用docker-machine安装的（docker-machine安装已经配置好相关的 tls证书）
