As I mentioned in my previous post I’ve been playing around with Vagrant for the past couple of days and I was trying to adapt a Vagrantfile that Nathan created a few months ago to do what I wanted.
I’m using Vagrant 1.2.2 and I started out with the following Vagrantfile:
Vagrant.configure("2") do |config|
config.vm.box = "precise64"
config.vm.box_url = "http://files.vagrantup.com/precise64.box"
config.vm.define :neo01 do |neo|
neo.vm.network :hostonly, "192.168.33.101"
neo.vm.forward_port 8080, 4569
end
end
Unfortunately a ‘vagrant up’ doesn’t quite work as expected:
$ vagrant up /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/plugins/kernel_v2/config/vm.rb:146:in `[]': can't convert Symbol into Integer (TypeError) from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/plugins/kernel_v2/config/vm.rb:146:in `network' from /Users/markneedham/projects/support/haproxy/Vagrantfile:19:in `block (2 levels) in <top (required)>' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/v2/loader.rb:37:in `call' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/v2/loader.rb:37:in `load' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/loader.rb:104:in `block (2 levels) in load' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/loader.rb:98:in `each' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/loader.rb:98:in `block in load' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/loader.rb:95:in `each' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/config/loader.rb:95:in `load' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:329:in `machine' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/plugin/v2/command.rb:131:in `block in with_target_vms' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/plugin/v2/command.rb:164:in `call' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/plugin/v2/command.rb:164:in `block in with_target_vms' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/plugin/v2/command.rb:163:in `map' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/plugin/v2/command.rb:163:in `with_target_vms' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/plugins/commands/up/command.rb:42:in `block in execute' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:206:in `block (2 levels) in batch' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:204:in `tap' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:204:in `block in batch' from <internal:prelude>:10:in `synchronize' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:203:in `batch' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/plugins/commands/up/command.rb:41:in `execute' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/cli.rb:46:in `execute' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/lib/vagrant/environment.rb:467:in `cli' from /Applications/Vagrant/embedded/gems/gems/vagrant-1.2.2/bin/vagrant:84:in `<top (required)>' from /Applications/Vagrant/bin/../embedded/gems/bin/vagrant:23:in `load' from /Applications/Vagrant/bin/../embedded/gems/bin/vagrant:23:in `<main>'
The problem line is ‘neo.vm.network :hostonly, “192.168.33.101″‘ which I learnt is because the way you setup networking has changed slightly between the versions.
We now need something like this:
Vagrant.configure("2") do |config|
config.vm.box = "precise64"
config.vm.box_url = "http://files.vagrantup.com/precise64.box"
config.vm.define :neo01 do |neo|
neo.vm.network :private_network, ip: "192.168.33.101"
neo.vm.forward_port 8080, 4569
end
end
If we run ‘vagrant up’ again we’ll see that error has been removed and we have a new one!
$ vagrant up Bringing machine 'neo01' up with 'virtualbox' provider... There are errors in the configuration of this machine. Please fix the following errors and try again: vm: * The following settings don't exist: forward_port
It turns out the way that we do port forwarding has also changed. Annoyingly if you google ‘vagrant port forwarding’ it still points you to the old documentation rather than the newer one.
We need to change our code to the following:
Vagrant.configure("2") do |config|
config.vm.box = "precise64"
config.vm.box_url = "http://files.vagrantup.com/precise64.box"
config.vm.define :neo01 do |neo|
neo.vm.network :private_network, ip: "192.168.33.101"
neo.vm.network :forwarded_port, host: 4569, guest: 8080
end
end
If we run ‘vagrant up’ now it’s much happier:
$ vagrant up Bringing machine 'neo01' up with 'virtualbox' provider... [neo01] Setting the name of the VM... [neo01] Clearing any previously set forwarded ports... ...
