Setting up a VM hostname: undefined method `hostname'

Question

I'm trying to set host name for VM. Here my Vagrantfile:

Vagrant::Config.run do |config|
  config.vm.box = "opensuse-12.3-32"
  config.vm.define :web do |web_config|
    web_config.vm.hostname "web.my.net"
    web_config.vm.forward_port 80, 7080
    web_config.vm.provision :puppet do |puppet|
      puppet.manifests_path = "puppet"
      puppet.module_path = "puppet/modules"
      puppet.manifest_file  = "base.pp"
    end
  end
end

But it leads to the following error:

/home/coder/vagrant/opensuse/Vagrantfile:40:in `block (2 levels) in <top (required)>': undefined method `hostname' for #<VagrantPlugins::Kernel_V1::VMConfig:0x00000002748fb8> (NoMethodError)

I'm using Vagrant 1.3.1 under Ubuntu 12.10. (64 bit) and OpenSuSe 12.3 (32 bit) as VM.

Answer 1

What you have is a mismatch between your code and the version of the Vagrant API you are using.

• For Vagrant API v1 use config.vm.host_name.
• For Vagrant API v2 use config.vm.hostname.

Answer 2

Try:

web_config.vm.hostname = "web.my.net"

Answer 3

As per issue #1974, setting hostname you should be using => config.vm.hostname = "web.my.net"

So the block should look like

  config.vm.define :web do |web_config|
    web_config.vm.hostname = "web.my.net"
    web_config.vm.forward_port 80, 7080
    web_config.vm.provision :puppet do |puppet|
      puppet.manifests_path = "puppet"
      puppet.module_path = "puppet/modules"
      puppet.manifest_file  = "base.pp"
    end
  end

You can even generate some random hostname by using code below

config.vm.hostname = "devops#{rand(01..99)}.vagrant.vm}"
