Vagrant. Usefull Snippets

I put together small collection of usefull commands and Vagrant file snippets.

Destroy and start new insatnce from one line:

vagrant destroy -f && vagrant up

To change parameters of virtual machine:

1
2
3
4
5

  config.vm.provider :virtualbox do |vb|
    vb.customize ["modifyvm", :id, "--memory", "1024"]
    vb.customize ["modifyvm", :id, "--cpus", "2"]
    vb.customize ["modifyvm", :id, "--ioapic", "on"]
  end

Make sure --ioapic is on

Link local folder to cache apt-get packages

It is very annoying to wait when packages being downloaded. Here is how to do it only once.

Create method in header of your Vagrant file:

1
2
3
4
5
6
7
8
9

    def local_cache(box_name)
      cache_dir = File.join(File.expand_path("~/.vagrant"),
                            'cache',
                            'apt',
                            box_name)
      partial_dir = File.join(cache_dir, 'partial')
      FileUtils.mkdir_p(partial_dir) unless File.exists? partial_dir
      cache_dir
    end

Use it inside configuration:

1
2

  cache_dir = local_cache(config.vm.box)
  config.vm.synced_folder cache_dir, "/var/cache/apt/archives/"

Create local virtual IP address:

1

  config.vm.network :private_network, ip: "88.88.88.88"
