Setting up a Vagrant box on EC2, how to get the "session token"

Question

I have:

An AWS account with free tier
An Ubuntu 14.04 LTS laptop with a PEM file, and I can create EC2 instances, and SSH into them.
AWS command line installed on my laptop
Vagrant installed on the laptop
AWS plugin installed on Vagrant

In the AWS plugin readme file it gives a template for a Vagrant file:

Vagrant.configure("2") do |config|
  config.vm.box = "dummy"

  config.vm.provider :aws do |aws, override|
    aws.access_key_id = "YOUR KEY"
    aws.secret_access_key = "YOUR SECRET KEY"
    aws.session_token = "SESSION TOKEN"
    aws.keypair_name = "KEYPAIR NAME"

    aws.ami = "ami-7747d01e"

    override.ssh.username = "ubuntu"
    override.ssh.private_key_path = "PATH TO YOUR PRIVATE KEY"
  end
end

How do I get aws.session_token = "SESSION TOKEN" ?

session_token is the STS (Security Token Service) session token.

you would get the value from amazon CLI (installed and configured to work with your account)

fhenri@machine:~$ aws sts get-session-token --duration-seconds 129600
{
    "Credentials": {
        "SecretAccessKey": "xxxxxxxx",
        "SessionToken": "your token value",
        "Expiration": "2015-11-12T14:23:22Z",
        "AccessKeyId": "xxxxxx"
    }
}
