我是靠谱客的博主娇气芒果，最近开发中收集的这篇文章主要介绍Docker Machine，觉得挺不错的，现在分享给大家，希望可以做个参考。

Docker machine搭建遇到的问题:Error with pre-create check: “VBoxManage not found. Make sure VirtualBox is

docker machine

写的很不错

1.简介

Docker Machine是Docker官方三剑客项目之一，负责使用Docker的第一步，在多种平台上快速安装Docker环境。它支持多种平台，让用户可以在很短时间内搭建一套Docker主机集群。

Machine项目主要由Go编写，用户可以在本地任意指定被Machine管理的Docker主机，并对其进行操作。Machine定位是“在本地或者云环境中创建Docker主机（Create Docker hosts on your computer，on cloud providers，and inside your own data center.）”。

其基本功能包括：

·在指定节点上安装Docker引擎，配置其为Docker主机；

·集中管理所有Docker主机。

Machine连接不同类型的节点是通过不同驱动指定的，目前已经支持了包括IBM、Amazon、Google等多家数据中心的云主机。

2.安装

base=https://github.com/docker/machine/releases/download/v0.16.0 &&   curl -L $base/docker-machine-$(uname -s)-$(uname -m) >/tmp/docker-machine &&   sudo mv /tmp/docker-machine /usr/local/bin/docker-machine &&   chmod +x /usr/local/bin/docker-machine

3.通过VirtualBox来创建的例子

3.1 报错VBoxManage not found

Make sure VirtualBox is installed and VBoxManage is in the path

安装virtualbox

3.2 This computer doesn't have VT-X/AMD-v enabled.

[root@wknode doc]# docker-machine create --driver=virtualbox vbox-instance
Running pre-create checks...
Error with pre-create check: "This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory"

解决方案:

3.3 成功创建一个虚拟机器并为其安装docker环境

[root@wknode muten003]# docker-machine create --driver=virtualbox  vbox-instance
Running pre-create checks...
Creating machine...
(vbox-instance) Copying /root/.docker/machine/cache/boot2docker.iso to /root/.docker/machine/machines/vbox-instance/boot2docker.iso...

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env vbox-instance
[root@wknode muten003]# docker-machine env vbox-instance
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/vbox-instance"
export DOCKER_MACHINE_NAME="vbox-instance"
# Run this command to configure your shell: 
# eval $(docker-machine env vbox-instance)

3.4 远程登录被刚刚创建的虚拟机器

[root@wknode muten003]# docker-machine ssh vbox-instance
   ( '>')
  /) TC (   Core is distributed with ABSOLUTELY NO WARRANTY.
 (/-_--_-)           www.tinycorelinux.net


vim  /etc/ssh/sshd_config将PermitRootLogin yes的注释放开，sudo systemctl restart sshd
[root@wknode cppHelloWorld]# docker-machine create --driver generic --generic-ip-address=192.168.244.142 node-work
Docker machine "node-work" already exists
[root@wknode cppHelloWorld]#

3.5 切换环境查看被控制机器的情况

[root@wknode muten003]# docker-machine env vbox-instance
export DOCKER_TLS_VERIFY="1"
export DOCKER_HOST="tcp://192.168.99.100:2376"
export DOCKER_CERT_PATH="/root/.docker/machine/machines/vbox-instance"
export DOCKER_MACHINE_NAME="vbox-instance"
# Run this command to configure your shell: 
# eval $(docker-machine env vbox-instance)
[root@wknode muten003]# 
[root@wknode muten003]# eval $(docker-machine env vbox-instance)
[root@wknode muten003]# docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE

3.6 将环境切换回docker-machine所在机器

[root@wknode muten003]# docker-machine env -u
unset DOCKER_TLS_VERIFY
unset DOCKER_HOST
unset DOCKER_CERT_PATH
unset DOCKER_MACHINE_NAME
# Run this command to configure your shell: 
# eval $(docker-machine env -u)
[root@wknode muten003]# docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE
[root@wknode muten003]# 
[root@wknode muten003]# eval $(docker-machine env -u)
[root@wknode muten003]# docker images
REPOSITORY                                           TAG       IMAGE ID       CREATED         SIZE
