Description

Today vagrantfile_template needs to be a file path.

Allow to specify vagrantfile_template_content in Vagrant post processor so I can use templatefile with it.

Use Case(s)

I want to specify my own SSH to be used in Vagrant instead of the public one therefore I would like to inject a vagrant with the following:

Vagrant.configure("2") do |config|
  config.ssh.private_key_path = ${my_ssh_key}
  config.ssh.forward_agent = true
end

This could be applied many configurations in the Vagrantfile. This is only an example.

Potential configuration

locals {
   vagrantfile = templatefile("vagrantfile.pkrtpl.hcl", { 
      my_ssh_key = "~/.ssh/rsa
    })
 }
 ....
 post-processor "vagrant" {
    vagrantfile_template_content = local.vagrantfile
 }
