How to ssh to vagrant without actually running “vagrant ssh”?

Question

I would like to reproduce the way Vagrant logs in to my VM within a shell script using an ssh command, so I create an alias to my Vagrant instance.

Vagrant stores the private key in ~/.vagrant.d/insecure_private_key and uses it to connect to every machine through ssh, considering that it is configured to connect on port 2200 (default) it would be something like:

ssh vagrant@localhost -p 2200 -i ~/.vagrant.d/insecure_private_key

Note: make sure that the private key is owned by the user running Vagrant.

Though if your aim is to have a multi-machine environment you may do so using config.vm.define.

Here's an example illustrating an environment with 2 machines, one called web and the other is databases:

config.vm.define 'web', primary: true do |web|
        web.vm.box = 'CentOS64'
        web.vm.hostname = 'vic-develop'
        web.vm.network 'private_network', ip: '192.168.50.10', virtualbox__intnet: true
        web.vm.synced_folder '../code', '/var/www/project', :mount_options => ["dmode=777,fmode=777"]

        web.vm.provision 'ansible' do |ansible|
            ansible.playbook = 'development-web.yml'
            ansible.sudo = true
        end
end

config.vm.define 'databases' do |db|
    db.vm.box = 'CentOS64'

    db.vm.network 'private_network', ip: '192.168.50.20', virtualbox__intnet: true
    db.vm.network :forwarded_port, guest: 3306, host: 8206

    db.vm.provision 'ansible' do |ansible|
        ansible.playbook = 'development-db.yml'
        ansible.sudo = true
    end
end

Then you will have all Vagrant commands available per machine, i.e. vagrant ssh web and vagrant provision databases.
