Docker Machine 入门实践@FreeBSD

本文主要是介绍Docker Machine 入门实践@FreeBSD，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在这篇文档里，我们安装了docker machine：FreeBSD安装Docker记录-CSDN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-CSDN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 | 菜鸟教程

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

输出信息

{"ConfigVersion": 3,"Driver": {"IPAddress": "","MachineName": "myvm","SSHUser": "docker","SSHPort": 0,"SSHKeyPath": "","StorePath": "/home/skywalk/.docker/machine","SwarmMaster": false,"SwarmHost": "tcp://0.0.0.0:3376","SwarmDiscovery": "","VBoxManager": {},"HostInterfaces": {},"CPU": 1,"Memory": 1024,"DiskSize": 20000,"NatNicType": "82540EM","Boot2DockerURL": "","Boot2DockerImportVM": "","HostDNSResolver": false,"HostOnlyCIDR": "192.168.99.1/24","HostOnlyNicType": "82540EM","HostOnlyPromiscMode": "deny","UIType": "headless","HostOnlyNoDHCP": false,"NoShare": false,"DNSProxy": true,"NoVTXCheck": false,"ShareFolder": ""},"DriverName": "virtualbox","HostOptions": {"Driver": "","Memory": 0,"Disk": 0,"EngineOptions": {"ArbitraryFlags": [],"Dns": null,"GraphDir": "","Env": [],"Ipv6": false,"InsecureRegistry": [],"Labels": [],"LogLevel": "","StorageDriver": "","SelinuxEnabled": false,"TlsVerify": true,"RegistryMirror": [],"InstallURL": "https://get.docker.com"},"SwarmOptions": {"IsSwarm": false,"Address": "","Discovery": "","Agent": false,"Master": false,"Host": "tcp://0.0.0.0:3376","Image": "swarm:latest","Strategy": "spread","Heartbeat": 0,"Overcommit": 0,"ArbitraryFlags": [],"ArbitraryJoinFlags": [],"Env": null,"IsExperimental": false},"AuthOptions": {"CertDir": "/home/skywalk/.docker/machine/certs","CaCertPath": "/home/skywalk/.docker/machine/certs/ca.pem","CaPrivateKeyPath": "/home/skywalk/.docker/machine/certs/ca-key.pem","CaCertRemotePath": "","ServerCertPath": "/home/skywalk/.docker/machine/machines/myvm/server.pem","ServerKeyPath": "/home/skywalk/.docker/machine/machines/myvm/server-key.pem","ClientKeyPath": "/home/skywalk/.docker/machine/certs/key.pem","ServerCertRemotePath": "","ServerKeyRemotePath": "","ClientCertPath": "/home/skywalk/.docker/machine/certs/cert.pem","ServerCertSANs": [],"StorePath": "/home/skywalk/.docker/machine/machines/myvm"}},"Name": "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.netdocker@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:
(docker@127.0.0.1) Password for docker@x250:
Error getting IP address: ssh command error:
command : ip addr show
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。
