Add public key to vagrant's authorized_keys

Vagrantfile

id_rsa_key_pub = File.read(File.join(Dir.home, ".ssh", "id_rsa.pub"))

config.vm.provision :shell,
        :inline => "echo 'appending SSH Pub Key to ~vagrant/.ssh/authorized_keys' && echo '#{id_rsa_key_pub }' >> /home/vagrant/.ssh/authori
zed_keys && chmod 600 /home/vagrant/.ssh/authorized_keys"

config.ssh.insert_key = false

Hi, thanks for the useful gist but there is one problem here, you need to add chown vagrant:vagrant /home/vagrant/.ssh/authorized_keys in order for it to work, because with these command the file is owned by root and has 0600 permissions which prevent vagrant user from reading it.
