## 安装virtualbox ##

如果要使用virtualbox，首先要安装virtualbox

\[[download for virtualbox][]\]

## docker machine基本使用 ##

可以在~/.bashrc中设置alias dm='docker-machine'简化输入

**创建一个dockermachine**

**pika:~$docker-machine create --driver virtualbox pydm**

Note: --driver  <=>  -d

**查看当前的machine**

**pika:~$dm ls**  
NAME   ACTIVE   DRIVER       STATE     URL                         SWARM   DOCKER    ERRORS

pydm   -        virtualbox   Running   tcp://192.168.99.100:2376           v1.10.3

Get the environment commands for your new VM.As noted in the output of the docker-machine create command, you need to tell Docker to talk to the new machine.

**pika:~$**

**dm env pydm**

export DOCKER\_TLS\_VERIFY="1"  
export DOCKER\_HOST="tcp://192.168.99.100:2376"  
export DOCKER\_CERT\_PATH="/home/pika/.docker/machine/machines/pydm"  
export DOCKER\_MACHINE\_NAME="pydm"  
\# Run this command to configure your shell:   
\# eval $(docker-machine env pydm)

**pika:~$**

**eval $(docker-machine env pydm)**

查看docker相关信息也会改变，这时，docker指向的是docker machine pydm，而不是系统中的docker了，之前在系统中创建的docker images都会没有了

pika:~$docker info

之后就可以按照docker的使用来配置环境了。。。如可以使用\[[Docker教程：使用docker配置python开发环境][Docker_docker_python]\-Docker开发环境配置\]来配置python开发环境

\[[Get started with Docker Machine and a local VM][]\]

\[[Docker Machine快速安装Docker环境（二）][Docker Machine_Docker]\]

注意，每次重启后，docker machine可能关闭，要重新打开相应的docker machine，并设置docker为dm中的docker

**dm start pydm**

**eval $(docker-machine env pydm)**

## docker-machine命令 ##

help 查看帮助信息，输入docker-machine help就会出现下面内容  
active 查看活动的Docker主机  
config 输出连接的配置信息  
create 创建一个Docker主机  
env 显示连接到某个主机需要的环境变量  
inspect 输出主机更新信息

### 获取Docker主机地址 ###

docker-machine ip default

可能错误：Host does not exist: "default"

check what machine has been created (docker-machine ls)

docker-machine create default

可能的错误：Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"``

\#docker-machine create -d virtualbox default

sudo apt-get install -y virtualbox-qt

kill 停止某个Docker主机  
ls 列出所有管理的Docker主机  
regenerate-certs 为某个主机重新成功TLS认证信息  
restart 重启Docker主机  
rm 删除Docker主机  
scp 在Docker主机之间复制文件  
ssh SSH到主机上执行命令  
**start 启动一个主机**  
status 查看一个主机状态  
stop 停止一个主机  
upgrade 更新主机Docker版本为最新  
url 获取主机的URL

具体命令参数及参考也可见\[[https://docs.docker.com/machine/reference/][https_docs.docker.com_machine_reference]\]
