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.
CFLAGS
If set the contents of this environment variable will be appended to the value generated by the Vagrant launcher.
CPPFLAGS
If set the contents of this environment variable will be appended to the value generated by the Vagrant launcher.
CURL_CA_BUNDLE
If set this environment variable will be passed through to the Vagrant process. By default Vagrant will use the CA certificate included with the Vagrant installation.
LDFLAGS
If set the contents of this environment variable will be appended to the value generated by the Vagrant launcher.
SSL_CERT_FILE
If set this environment variable will be passed through to the Vagrant process. By default Vagrant will use the CA certificate included with the Vagrant installation.
VAGRANT_ALIAS_FILE
VAGRANT_ALIAS_FILE
can be set to change the file where Vagrant aliases are
defined. By default, this is set to ~/.vagrant.d/aliases
.
VAGRANT_ALLOW_PLUGIN_SOURCE_ERRORS
If this is set to any value, then Vagrant will not error when a configured plugin source is unavailable. When installing a Vagrant plugin Vagrant will error and halt if a plugin source is inaccessible. In some cases it may be desirable to ignore inaccessible sources and continue with the plugin installation. Enabling this value will cause Vagrant to simply log the plugin source error and continue.
VAGRANT_BOX_UPDATE_CHECK_DISABLE
By default, Vagrant will query the metadata API server to see if a newer
box version is available for download. This optional can be disabled on a
per-Vagrantfile basis with config.vm.box_check_update
, but it can also be
disabled globally setting VAGRANT_BOX_UPDATE_CHECK_DISABLE
to any non-empty
value.
This option will not affect global box functions like vagrant box update
.
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 suppress these
calls, set the environment variable VAGRANT_CHECKPOINT_DISABLE
to any
non-empty value.
If you use other HashiCorp tools like Packer and would prefer to configure this
setting only once, you can set CHECKPOINT_DISABLE
instead.
VAGRANT_CWD
VAGRANT_CWD
can be set to change the working directory of Vagrant. By
default, Vagrant uses the current directory you are 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_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_DEFAULT_PROVIDER
This configures the default provider Vagrant will use.
This normally does not need to be set since Vagrant is fairly intelligent
about how to detect the default provider. By setting this, you will force
Vagrant to use this provider for any new Vagrant environments. Existing
Vagrant environments will continue to use the provider they came up
with.
Once you vagrant destroy
existing environments, this will take effect.
VAGRANT_DEFAULT_TEMPLATE
This configures the template used by vagrant init
when the --template
option
is not provided.
VAGRANT_DETECTED_ARCH
This environment variable may be set by the Vagrant launcher to help determine the current runtime architecture in use. In general Vagrant will set this value when running on a Windows host using a cygwin or msys based shell. The value the Vagrant launcher may set in this environment variable will not always match the actual architecture of the platform itself. Instead it signifies the detected architecture of the environment it is running within. If this value is set, the Vagrant launcher will not modify it.
VAGRANT_DETECTED_OS
This environment variable may be set by the Vagrant launcher to help determine the current runtime platform. In general Vagrant will set this value when running on a Windows host using a cygwin or msys based shell. If this value is set, the Vagrant launcher will not modify it.
VAGRANT_DISABLE_RESOLV_REPLACE
Vagrant can optionally use the Ruby Resolv library in place of the libc resolver. This can be disabled setting this environment variable.
VAGRANT_DISABLE_VBOXSYMLINKCREATE
If set, this will completely disable the ability to create symlinks with all VirtualBox
shared folders. If this environment variable is not set, the VirtualBox synced
folders option SharedFoldersEnableSymlinksCreate
will be enabled by default.
This option can be overridden on a per-folder basis within your Vagrantfile
config by setting the SharedFoldersEnableSymlinksCreate
option to true if you
do not wish to completely disable this feature for all VirtualBox guests.
More information on the option can be read in the VirtualBox synced folders docs page.
VAGRANT_DISABLE_SMBMFSYMLINKS
If set, this will disable the mfsymlinks
option for mounting SMB filesystems. If not set, then the mfsymlinks
option will be enabled by default. This option can be overriden on a pre-folder basis with your Vagrantfile by setting mount_options: ['mfsymlinks']
.
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_ENABLE_RESOLV_REPLACE
Use the Ruby Resolv library in place of the libc resolver.
VAGRANT_FORCE_COLOR
If this is set to any value, then Vagrant will force colored output, even if it detected that there is no TTY or the current environment does not support it.
The equivalent behavior can be achieved by using the --color
flag on a
command-by-command basis. This environmental variable is useful for setting
this flag globally.
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_IGNORE_WINRM_PLUGIN
Vagrant will not display warning when vagrant-winrm
plugin is installed.
VAGRANT_INSTALL_LOCAL_PLUGINS
If this is set to any value, Vagrant will not prompt for confirmation prior to installing local plugins which have been defined within the local Vagrantfile.
VAGRANT_IS_HYPERV_ADMIN
Disable Vagrant's check for Hyper-V admin privileges and allow Vagrant to assume the current user has full access to Hyper-V. This is useful if the internal privilege check incorrectly determines the current user does not have access to Hyper-V.
VAGRANT_LOCAL_PLUGINS_LOAD
If this is set Vagrant will not stub the Vagrantfile when running
vagrant plugin
commands. When this environment variable is set the
--local
flag will not be required by vagrant plugin
commands to
enable local project plugins.
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 are 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_MAX_REBOOT_RETRY_DURATION
By default, Vagrant will wait up to 120 seconds for a machine to reboot. However, if you're finding your OS is taking longer than 120 seconds to reboot successfully, you can configure this environment variable and Vagrant will wait for the configured number of seconds.
VAGRANT_NO_COLOR
If this is set to any value, then Vagrant will not use any colorized output. This is useful if you are logging the output to a file or on a system that does not 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_PARALLEL
If this is set, Vagrant will not perform any parallel operations (such as parallel box provisioning). All operations will be performed in serial.
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 do not load any
plugins, so if you do install any unstable plugins, you can always use
the vagrant plugin
commands without having to worry.
VAGRANT_POWERSHELL_VERSION_DETECTION_TIMEOUT
Vagrant will use a default timeout when checking for the installed version of PowerShell. Occasionally the default can be too low and Vagrant will report being unable to detect the installed version of PowerShell. This environment variable can be used to extend the timeout used during PowerShell version detection.
When setting this environment variable, its value will be in seconds. By default, it will use 30 seconds as a timeout.
VAGRANT_PREFERRED_PROVIDERS
This configures providers that Vagrant should prefer.
Much like the VAGRANT_DEFAULT_PROVIDER
this environment variable normally
does not need to be set. By setting this you will instruct Vagrant to
prefer providers defined in this environment variable for any new
Vagrant environments. Existing Vagrant environments will continue to use
the provider they came up
with. Once you vagrant destroy
existing environments,
this will take effect. A single provider can be defined within this environment
variable or a comma delimited list of providers.
VAGRANT_PREFER_SYSTEM_BIN
If this is set, Vagrant will prefer using utility executables (like ssh
and rsync
)
from the local system instead of those vendored within the Vagrant installation.
Vagrant will default to using a system provided ssh
on Windows. This
environment variable can also be used to disable that behavior to force Vagrant to
use the embedded ssh
executable by setting it to 0
.
VAGRANT_WINCURL_DISABLE
If set Vagrant will use the mingw build of curl which uses the installer provided ca-certificates bundle instead of the native Windows curl executable.
VAGRANT_SERVER_URL
This configures the remote server which Vagrant will connect to for fetching Vagrant boxes. By default this is configured for Vagrant Cloud (https://vagrantcloud.com)
VAGRANT_SERVER_ACCESS_TOKEN_BY_URL
If this is set Vagrant will change the way it authenticates with the configured Vagrant server. When set, the authentication behavior will be reverted to the deprecated authentication behavior of:
- not adding an authentication header to the request
- setting the configured access token as a query parameter on URLs
This behavior can be useful for third party servers which do not accept the authentication header currently used with Vagrant Cloud.
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 during 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 VAGRANT_SKIP_SUBPROCESS_JAILBREAK
.
VAGRANT_USER_AGENT_PROVISIONAL_STRING
Vagrant will append the contents of this variable to the default user agent header.
VAGRANT_USE_VAGRANT_TRIGGERS
Vagrant will not display the warning about disabling the core trigger feature if the community plugin is installed.
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.
VAGRANT_WINPTY_DISABLE
If this is set, Vagrant will not wrap interactive processes with winpty where required.
