Get Vagrant to run as different user and copying the pub key

[Byron Kim]

So I know you can use the following to run as a different user:

config.ssh.username = "ubuntu"
config.ssh.private_key_path = File.expand_path("../ssh_key", __FILE__)

I'm provisioning the default ubuntu/trusty64 on Virtualbox and if i use the --provider=aws flag, it will spin up an EC2 instance.  I'm also using Ansible to configure the VM/instance.  

The problem I'm running into is using the 'ubuntu' user to be configured.  I was hoping that there is a way to run a shell script prior to vagrant ssh'ing into the Virtualbox.  I tried running this as a shell script:

sudo cp -f /vagrant/ssh_key /home/ubuntu/.ssh/authorized_keys
sudo sed -i '/PasswordAuthentication yes/c\PasswordAuthentication no' /etc/ssh/sshd_config
sudo service ssh restart

But I believe vagrant will try to ssh first and then run the shell script.  Is there any way around this or do I have to build my own vagrant box and have this setting in place?

The reason I need to do this is because I'm referencing files in my Ansible playbook and it doesn't always interpret ~/ with the correct directory.  I could write out the whole path, vagrant's home path is /home/vagrant/ and the EC2 instance is /home/ubuntu/ and that would look messy.  I'm not 100% sure how I can have conditionals in place (as in Ansible knowing I'm running this on Virtualbox or AWS).

Hello.

Vagrant requires ssh to connect to the AWS box.

So you can use the keys that AWS give you.

If the AMI you want to use is not fit, and need some changes, then you can use packer to configure it and create a new ami:
