This file augments the standard Vagrantfile with some developer-specific settings.
You can override any settings you want. This file is in .gitignore, so can be specific
to your own environment.

By default this file mounts your local development version of the Deis codebase onto the
Deis Controller. It does this by mounting your code onto the VM at /vagrant, then moving
the original installed code base to /opt/deis/controller_ORIG and symlinking
/opt/deis/controller to the mounted code at /vagrant.

Because the deployed environment creates some extra files, like /deis/local_settings.py
for example, these need to be then symlinked into the symlinked mount. Sound complicated?
Yo dawg, I heard you like symlinks.

HOST_CODE_PATH = '/opt/deis/controller'

# These paths are either in .gitignore or created after installation.
# Therefore they need to be linked into the dev codebase.
symlinks = [
  'deis/local_settings.py',
  '.secret_key',
  'logs',
