在这篇文档里，我们安装了docker machine：FreeBSD安装Docker记录-****博客
在这篇文档里，我们启动虚拟主机myvm并进入虚拟主机：boot2docker实践@FreeBSD-****博客
现在开始更深入的进行 docker的实战演练。参考Docker Machine官方文档：Docker Machine |
Docker Machine 入门实践
基本操作
在FreeBSD系统中，使用docker-machine命令查看一下docker：
docker-machine ls
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
myvm * virtualbox Running Unknown Machine does not have a host-only adapter
testmyvm - virtualbox Stopped Unknown
就像前面文档中讲到的，可以使用如下命令创建一个：
docker-machine create --driver virtualbox test查询docker ip
docker-machine ip myvm停止和启动
docker-machine stop myvm
docker-machine start myvm进入机器
docker-machine ssh myvm进阶操作
查看虚拟主机的情况
docker-machine inspect myvm

现在还无法通过docker-machine命令获得虚拟机的ip地址等信息，只好到virtual box中查看ip，发现是192.168.5.102 ，可以通过ssh来登录它。
ssh docker@192.168.56.102
docker@192.168.56.102's password:
( '>')
/) TC (\ Core is distributed with ABSOLUTELY NO WARRANTY.
(/-_--_-\) www.tinycorelinux.net
docker@boot2docker:~$
这样至少也可以开始后面的docker操作了。
总结：
前段时间整docker的时候，弄出来的docker-machine ,现在终于算是会玩了。
整个流程就是：
FreeBSD下使用pkg install docker-machine安装docker-machine，
然后可以使用docker-machine命令创建tiny-linux核心的boot2docker虚拟主机，并可在virtual-box中启动这个虚拟主机。boot2docker虚拟主机里面有全套的docker实现套件，这样就可以开始docker之旅了。
这就是在FreeBSD系统下进行docker的终极解决方案。
boot2docker本来是为了mac os和windows下使用docker而生的，但是后来mac和win下都有了docker实现，反而现在成了FreeBSD下的解决方案，真是事事难料、造化弄人啊！
调试
虚拟机报错Error getting IP address: Machine does not have a host-only adapter
在vitrual-machine里给myvm虚拟机设定一块host-only的网卡
命令docker-machine ip报错err : exit status 255
docker-machine ip myvm
(docker@127.0.0.1) Password for docker@x250:
(docker@127.0.0.1) Password for docker@x250:

err : exit status 255
output :
提示需要输入docker的密码，我要想想...
问题是这个密码是啥时候输入、设定的啊！先保留问题，后面发现可以暂时不输入口令跳过，但是不知道这样处理是否正确（感觉肯定是有问题的）
docker-machine start myvm 报错
docker-machine start myvm
Starting "myvm"...
(myvm) Check network to re-create if needed...
(myvm) Found a new host-only adapter: "vboxnet16"
Error setting up host only network on machine start: /usr/local/bin/VBoxManage hostonlyif ipconfig vboxnet16 --ip 192.168.99.1 --netmask 255.255.255.0 failed:
VBoxManage: error: Code E_ACCESSDENIED (0x80070005) - Access denied (extended info not available)
VBoxManage: error: Context: "EnableStaticIPConfig(Bstr(pszIp).raw(), Bstr(pszNetmask).raw())" at line 242 of file VBoxManageHostonly.cpp
这个没解决，暂时采用到Virtual-box里面手动开机处理。
boot2docker默认的用户名和密码
在 boot2docker 中，默认的用户名和密码是：
user: docker pass: tcuser
登录方法：
$ ssh docker@localhost -p 2022
不过这个登录方法，在FreeBSD下，还没法用，因为根本就没看到2022端口啊。
