Environmental Variables
Vagrant has a set of environmental variables that can be used to configure and control it in a global way. This page lists those environmental variables.
VAGRANT_DEBUG_LAUNCHER
For performance reasons, especially for Windows users, Vagrant uses a static
binary to launch the actual Vagrant process. If you have very early issues
when launching Vagrant from the official installer, you can specify the
VAGRANT_DEBUG_LAUNCHER environment variable to output debugging information
about the launch process.
VAGRANT_CHECKPOINT_DISABLE
Vagrant does occasional network calls to check whether the version of Vagrant
that is running locally is up to date. We understand that software making remote
calls over the internet for any reason can be undesirable. To surpress these
calls, set the environment variable VAGRANT_CHECKPOINT_DISABLE to any
non-empty value.
VAGRANT_CWD
VAGRANT_CWD can be set to change the working directory of Vagrant. By
default, Vagrant uses the current directory you're in. The working directory
is important because it is where Vagrant looks for the Vagrantfile. It
also defines how relative paths in the Vagrantfile are expanded, since they're
expanded relative to where the Vagrantfile is found.
This environmental variable is most commonly set when running Vagrant from a scripting environment in order to set the directory that Vagrant sees.
VAGRANT_DOTFILE_PATH
VAGRANT_DOTFILE_PATH can be set to change the directory where Vagrant stores VM-specific state, such as the VirtualBox VM UUID. By default, this is set to .vagrant. If you keep your Vagrantfile in a Dropbox folder in order to share the folder between your desktop and laptop (for example), Vagrant will overwrite the files in this directory with the details of the VM on the most recently-used host. To avoid this, you could set VAGRANT_DOTFILE_PATH to .vagrant-laptop and .vagrant-desktop on the respective machines. (Remember to update your .gitignore!)
VAGRANT_HOME
VAGRANT_HOME can be set to change the directory where Vagrant stores
global state. By default, this is set to ~/.vagrant.d. The Vagrant home
directory is where things such as boxes are stored, so it can actually become
quite large on disk.
VAGRANT_LOG
VAGRANT_LOG specifies the verbosity of log messages from Vagrant.
By default, Vagrant does not actively show any log messages.
Log messages are very useful when troubleshooting issues, reporting bugs, or getting support. At the most verbose level, Vagrant outputs basically everything it is doing.
Available log levels are "debug," "info," "warn," and "error." Both "warn" and "error" are practically useless since there are very few cases of these, and Vagrant generally reports them within the normal output.
"info" is a good level to start with if you're having problems, because while it is much louder than normal output, it is still very human-readable and can help identify certain issues.
"debug" output is extremely verbose and can be difficult to read without some knowledge of Vagrant internals. It is the best output to attach to a support request or bug report, however.
VAGRANT_NO_COLOR
If this is set to any value, then Vagrant will not use any colorized output. This is useful if you're logging the output to a file or on a system that doesn't support colors.
The equivalent behavior can be achieved by using the --no-color flag
on a command-by-command basis. This environmental variable is useful
for setting this flag globally.
VAGRANT_NO_PLUGINS
If this is set to any value, then Vagrant will not load any 3rd party plugins. This is useful if you install a plugin and it is introducing instability to Vagrant, or if you want a specific Vagrant environment to not load plugins.
Note that any vagrant plugin commands automatically don't load any
plugins, so if you do install any unstable plugins, you can always use
the vagrant plugin commands without having to worry.
VAGRANT_SKIP_SUBPROCESS_JAILBREAK
As of Vagrant 1.7.3, Vagrant tries to intelligently detect if it is running in the installer or running via Bundler. Although not officially supported, Vagrant tries its best to work when executed via Bundler. When Vagrant detects that you have spawned a subprocess that lives outside of Vagrant's installer, Vagrant will do its best to reset the preserved environment dring the subprocess execution.
If Vagrant detects it is running outside of the officially installer, the
original environment will always be restored. You can disable this automatic
jailbreak by setting the VAGRANT_SKIP_SUBPROCES_JAILBREAK.
VAGRANT_VAGRANTFILE
This specifies the filename of the Vagrantfile that Vagrant searches for. By default, this is "Vagrantfile." Note that this is not a file path, but just a filename.
This environmental variable is commonly used in scripting environments where a single folder may contain multiple Vagrantfiles representing different configurations.
