How to determine vagrant_machine_name from within VM

[grasmash]

I'd like to get the value of vagrant_machine_name while in the VM. Since I don't know what it may be for a given vm, I do not the path of the config.yml file (which I would otherwise parse for the value). I also cannot use hostname given the variability of domain name structure.

Is there an environmental variable or other means to determine this and other such ansible configuration values from within the VM?

@grasmash - A few things that should be helpful:

1. The root folder should always be mounted at /vagrant by default.
2. You could add a shell provisioner in a Vagrantfile.local or overriding Vagrantfile that runs inside the guest and stores the machine name in a file somewhere (see this answer).
3. IIRC, the hostname (determined by running hostname in the VM) should be the machine name...

Also, you can check if /home/vagrant exists, or if vagrant is in /etc/passwd.

Ah, knowing that the mount point is always at /vagrant is good enough!

VAGRANT_MACHINE_NAME=$(grep vagrant_machine_name: /vagrant/box/config.yml | cut -d' ' -f 2).

Thanks!

99% of the time—you can technically override it and not mount it, but people rarely do that :)
