vagrant config networking

10 August 2015

port forwarding

  1. demo

    1. Vagrantfile

       Vagrant.configure(2) do |config|
     config.vm.box = "ubuntu/trusty64"
     config.vm.network :forwarding_port, guest: 80, host: 8800
 end

    2. boot messages

       ==> default: Forwarding ports...
     default: 80 => 8800 (adapter 1)
     default: 22 => 2222 (adapter 1)

  2. forbid remote access to the forwarded port

         host_ip: "127.0.0.1"

     # config.vm.network :forwarding_port, guest: 80, host: 8800
     # this configuration allows everyone who knows your ip address
     # to access your web server

port collision

  1. demo

    1. autocorrecting port collision

       Vagrant.configure(2) do |config|
     config.vm.box = "ubuntu/trusty64"
     config.vm.network :forwarded_port, guest: 80, host: 8800, auto_correct: true
 end

private networks

  1. demo

    1. manual configuration

       Vagrant.configure(2) do |config|
     config.vm.box = "ubuntu/trusty64"
     config.vm.network "private_network", ip: "192.168.100.100"
 end

    2. dhcp configuration

       Vagrant.configure(2) do |config|
     config.vm.box = "ubuntu/trusty64"
     config.vm.network "private_network", type: "dhcp"
 end

  2. 2 guest use private network

    1. vbox1

       # 1. `Vagrantfile`
 Vagrant.configure(2) do |config|
     config.vm.box = "ubuntu/trusty64"
     config.vm.network "private_network", ip: "192.168.200.100"
 end

    3. ifconfig on host when vbox1 up

       # host
 $ ifconfig
 ...
 vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
     ether 0a:00:27:00:00:00 
 vboxnet1: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
     ether 0a:00:27:00:00:01 
 vboxnet2: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
     ether 0a:00:27:00:00:02 
     inet 192.168.200.1 netmask 0xffffff00 broadcast 192.168.200.255

    4. ifconfig on host when vbox2 up

       # host
 $ ifconfig
 vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
     ether 0a:00:27:00:00:00

     ether 0a:00:27:00:00:02 
     inet 192.168.200.1 netmask 0xffffff00 broadcast 192.168.200.255

     ether 0a:00:27:00:00:03 
     inet 192.168.100.1 netmask 0xffffff00 broadcast 192.168.100.255

  3. remove interfaces from host

    1. destroy guest machine

       # host
 $ cd vbox1
 $ vagrant destroy
 $ cd ../vbox2
 $ vagrant destroy

    2. remove interfaces

       # host
 $ VBoxManage hostonlyif remote vboxnet2
 $ VBoxManage hostonlyif remote vboxnet3

    2. use bridge parameter

       # 1. host
 config.vm.network "public_network", bridge: 'en1: Wi-Fi (AirPort)'

 # 2. host

    3. not use dhcp and provide an ip

       config.vm.network "public_network", ip: "192.168.1.10"
