有没有办法强制停泊机使用特定的ip创建vm？

问题描述

有没有办法强制docker-machine使用特定的ip创建docker vm（假设ip可用）？

解决方案

在

：

  echoifconfig eth1 192.168.99.50 netmask 255.255.255.0 broadcast 192.168.99.255 up| docker-machine ssh prova-discovery sudo tee /var/lib/boot2docker/bootsync.sh> / dev / null 
  

  docker-machine ls 
 NAME ACTIVE DRIVER STATE URL SWARM 
 test-1  -  virtualbox运行tcp：//192.168.99.50：2376 test-1（master）
  

我已更新命令：

  echokill`more /var/run/udhcpc.eth1.pid`\\\
ifconfig eth1 192.168。 99.50网络掩码255.255.255.0 broadcast 192.168.99.255 up| docker-machine ssh prova-discovery sudo tee /var/lib/boot2docker/bootsync.sh> / dev / null 
  

  docker-machine regenerate-certs prova-discovery 
  

（以您的码头机的名称替换 prova-discovery ）

这里是（Windows）脚本（ dmvbf.bat ）我现在使用，基于上面的内容：

  @echo off 
 setlocal enabledelayedexpansion 
 set machine =％1 
如果％machine％= =（
 echo dmvbf期望机器名称
 exit / b 1 
）
 set ipx =％2 
如果％ipx％== （
 echo dmvbf x missing ^（for 192.168.xy ^）
 exit / b 2 
）
 set ipy =％3 
如果％ipy％= =（
 echo dmvbf y missing ^（for 192.168.xy ^）
 exit / b 3 
）
 
 echo kill $（more / var / run /udhcpc.eth1。 pid）| docker-machine ssh％machine％sudo tee /var/lib/boot2docker/bootsync.sh> NUL 
 echo ifconfig eth1 192.168。％ipx％。％ipy％netmask 255.255.255.0 broadcast 192.168。％ipx％.255 | | docker-machine ssh％machine％sudo tee -a /var/lib/boot2docker/bootsync.sh> NUL 
 
 docker-machine ssh％machine％sudo cat /var/run/udhcpc.eth1 .pid | xargs sudo kill
 
 docker-machine ssh％machine％sudo ifconfig eth1 192.168。％ipx％。％ipy％netmask 255.255.255.0 broadcast 192.168。％ipx％.255 up
  

我启动vm（ docker-machine start< machine-name> / code>），然后：

  dmvbf< machine-name> 99 101 
  

我只做一次。

在下一个 docker-machine start< machine-name> 中，IP将为192.168.99.101。

Is there a way to force docker-machine to create the docker vm with a specific ip (assuming that ip is available)?

解决方案

That is actively requested in docker/machine issue 1709

The current workaround:

echo "ifconfig eth1 192.168.99.50 netmask 255.255.255.0 broadcast 192.168.99.255 up" | docker-machine ssh prova-discovery sudo tee /var/lib/boot2docker/bootsync.sh > /dev/null

docker-machine ls
NAME              ACTIVE   DRIVER       STATE     URL                                      SWARM
test-1                      -        virtualbox     Running   tcp://192.168.99.50:2376      test-1 (master)

I've updated the commands with:

echo "kill `more /var/run/udhcpc.eth1.pid`\nifconfig eth1 192.168.99.50 netmask 255.255.255.0 broadcast 192.168.99.255 up" | docker-machine ssh prova-discovery sudo tee /var/lib/boot2docker/bootsync.sh > /dev/null

docker-machine regenerate-certs prova-discovery

(replace prova-discovery by the name of your docker-machine)

Here is the (Windows) script (dmvbf.bat) I now use, based on what is above:

@echo off
setlocal enabledelayedexpansion
set machine=%1
if "%machine%" == "" (
    echo dmvbf expects a machine name
    exit /b 1
)
set ipx=%2
if "%ipx%" == "" (
    echo dmvbf x missing ^(for 192.168.x.y^)
    exit /b 2
)
set ipy=%3
if "%ipy%" == "" (
    echo dmvbf y missing ^(for 192.168.x.y^)
    exit /b 3
)

echo kill $(more /var/run/udhcpc.eth1.pid) | docker-machine ssh %machine% sudo tee /var/lib/boot2docker/bootsync.sh >NUL
echo ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up | docker-machine ssh %machine% sudo tee -a /var/lib/boot2docker/bootsync.sh >NUL

docker-machine ssh %machine% "sudo cat /var/run/udhcpc.eth1.pid | xargs sudo kill"

docker-machine ssh %machine% "sudo ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up"

I start the vm (docker-machine start <machine-name>), and then:

 dmvbf <machine-name> 99 101

I do that only once.

At the next docker-machine start <machine-name>, the IP will be 192.168.99.101.
