snippet to configure Vagrant to use SSH agent. Makes it easy to eg. access private git repositories from within VMs.

Vagrantfile

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|
  # ...
  # configure Vagrant to use SSH agent.  Makes it easy to access git from within VMs.
  config.vm.provision "shell" do |s|
    ssh_pub_key = `ssh-add -L`
    s.inline = <<-SHELL
      echo '#{ssh_pub_key}' >> /home/vagrant/.ssh/authorized_keys
      echo '#{ssh_pub_key}' >> /root/.ssh/authorized_keys
    SHELL
  end
  config.ssh.forward_agent = true
end
