创建虚拟主机

创建一个 oracle virtualbox 为驱动的虚拟主机，关于主机驱动可以参考官网：https://docs.docker.com/machine/drivers/

这时创建时使用了一个阿里的加速器

--engine-registry-mirror

[root@docker4 ~]# docker-machinecreate --driver virtualbox --engine-registry-mirror  host1

Creating CA:/root/.docker/machine/certs/ca.pem

Creating client certificate:/root/.docker/machine/certs/cert.pem

Running pre-create checks...

Error with pre-create check:"VBoxManage not found. Make sure VirtualBox is installed and VBoxManage isin the path"

这里出现了错误，是因为没有安装virtualbox

安装virtualbox

下载方法一：

下载地址，下载安装包，然后上传到/root

下载方法二：

[root@docker4 ~]# yum -yinstall wget

[root@docker4 ~]# wget

[root@docker4 ~]# yum -yinstall VirtualBox-5.1-5.1.20_114628_el7-1.x86_64.rpm

[root@docker4 ~]#docker-machine create --driver virtualbox --engine-registry-mirrorhttps://1rqn7spi.mirror.aliyuncs.com host1

Running pre-create checks...

Error with pre-create check: "This computerdoesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

此错误有两处需要注意：

1、BIOS需要开起硬件虚拟化支持

2、不要用Oracle VM virtaulbox创建虚拟机，Oracle VM virtaulbox不支持嵌套虚拟机。本文用的是VMware Workstation，所以是在 虚拟机->设置 里设置处理器的虚拟化引擎首选模式为“Intel VT-x/EPT 或AMD-V/RVI”及“虚拟化Intel VT-x/EPT 或AMD-V/RVI(V)”

到源码网址：https://github.com/boot2docker/boot2docker/releases 下载boot2docker.iso

然后上传到/root/.docker/machine/cache

[root@docker4 ~]# docker-machine create --driver virtualbox --engine-registry-mirror https://1rqn7spi.mirror.aliyuncs.com host1

To see how to connect your Docker Client to theDocker Engine running on this virtual machine, run: docker-machine env host1

到这里虚拟机就创建成功了。

下面查看虚拟机列表

[root@localmachine2host ~]# docker-machine ls

NAME    ACTIVE   DRIVER      STATE     URL                         SWARM   DOCKER       ERRORS

host1   -        virtualbox   Running  tcp://192.168.99.100:2376          v17.06.0-ce  

用本机docker客户端指向host1的docker

[root@localmachine2host ~]# eval $(docker-machine env host1)

[root@localmachine2host ~]# docker info
