Machine Settings

Config namespace: config.vm

The settings within config.vm modify the configuration of the machine that Vagrant manages.

Available Settings

  • config.vm.allow_fstab_modification (boolean) - If true, will add fstab entries for synced folders. If false, no modifications to fstab will be made by Vagrant. Note, this may mean that folders will not be automatically mounted on machine reboot. Defaults to true.

  • config.vm.allow_hosts_modification (boolean) - If false, will prevent Vagrant from writing to /etc/hosts. Defaults to true.

  • config.vm.base_mac (string) - The MAC address to be assigned to the default NAT interface on the guest. Support for this option is provider dependent.

  • config.vm.base_address (string) - The IP address to be assigned to the default NAT interface on the guest. Support for this option is provider dependent.

  • config.vm.boot_timeout (integer) - The time in seconds that Vagrant will wait for the machine to boot and be accessible. By default this is 300 seconds.

  • config.vm.box (string) - This configures what box the machine will be brought up against. The value here should be the name of an installed box or a shorthand name of a box in HashiCorp's Vagrant Cloud.

  • config.vm.box_check_update (boolean) - If true, Vagrant will check for updates to the configured box on every vagrant up. If an update is found, Vagrant will tell the user. By default this is true. Updates will only be checked for boxes that properly support updates (boxes from HashiCorp's Vagrant Cloud or some other versioned box).

  • config.vm.box_download_checksum (string) - The checksum of the box specified by config.vm.box_url. If not specified, no checksum comparison will be done. If specified, Vagrant will compare the checksum of the downloaded box to this value and error if they do not match. Checksum checking is only done when Vagrant must download the box. If this is specified, then config.vm.box_download_checksum_type must also be specified.

  • config.vm.box_download_checksum_type (string) - The type of checksum specified by config.vm.box_download_checksum (if any). Supported values are currently "md5", "sha1", "sha256", "sha384", and "sha512".

  • config.vm.box_download_client_cert (string) - Path to a client certificate to use when downloading the box, if it is necessary. By default, no client certificate is used to download the box.

  • config.vm.box_download_ca_cert (string) - Path to a CA cert bundle to use when downloading a box directly. By default, Vagrant will use the Mozilla CA cert bundle.

  • config.vm.box_download_ca_path (string) - Path to a directory containing CA certificates for downloading a box directly. By default, Vagrant will use the Mozilla CA cert bundle.

  • config.vm.box_download_options (map) - A map of extra download options to pass to the downloader. For example, a path to a key that the downloader should use could be specified as {key: "<path/to/key>"}. The keys should be options supported by curl using the unshortened form of the flag. For example, use append instead of a.

  • config.vm.box_download_insecure (boolean) - If true, then SSL certificates from the server will not be verified. By default, if the URL is an HTTPS URL, then SSL certs will be verified.

  • config.vm.box_download_location_trusted (boolean) - If true, then all HTTP redirects will be treated as trusted. That means credentials used for initial URL will be used for all subsequent redirects. By default, redirect locations are untrusted so credentials (if specified) used only for initial HTTP request.

  • config.vm.box_url (string, array of strings) - The URL that the configured box can be found at. If config.vm.box is a shorthand to a box in HashiCorp's Vagrant Cloud then this value does not need to be specified. Otherwise, it should point to the proper place where the box can be found if it is not installed. This can also be an array of multiple URLs. The URLs will be tried in order.

    Note that any client certificates, insecure download settings, and so on will apply to all URLs in this list. The URLs can also be local files by using the file:// scheme. For example: file://tmp/test.box.

  • config.vm.box_version (string) - The version of the box to use. This defaults to ">= 0" (the latest version available). This can contain an arbitrary list of constraints, separated by commas, such as: >= 1.0, < 1.5. When constraints are given, Vagrant will use the latest available box satisfying these constraints.

  • config.vm.cloud_init - Stores various cloud_init configurations on the machine. Currently experimental! Read the documentation for more information on how to enable this feature.

  • config.vm.communicator (string) - The communicator type to use to connect to the guest box. By default this is "ssh", but should be changed to "winrm" for Windows guests.

  • config.vm.disk - Stores various virtual disk configurations on the machine. Currently experimental! Read the documentation for more information on how to enable this feature.

  • config.vm.graceful_halt_timeout (integer) - The time in seconds that Vagrant will wait for the machine to gracefully halt when vagrant halt is called. Defaults to 60 seconds.

  • config.vm.guest (string, symbol) - The guest OS that will be running within this machine. This defaults to :linux, and Vagrant will auto-detect the proper distro. However, this should be changed to :windows for Windows guests. Vagrant needs to know this information to perform some guest OS-specific things such as mounting folders and configuring networks.

  • config.vm.hostname (string) - The hostname the machine should have. Defaults to nil. If nil, Vagrant will not manage the hostname. If set to a string, the hostname will be set on boot. If set, Vagrant will update /etc/hosts on the guest with the configured hostname.

  • config.vm.ignore_box_vagrantfile (boolean) - If true, Vagrant will not load the the settings found inside a boxes Vagrantfile, if present. Defaults to false.

  • config.vm.network - Configures networks on the machine. Please see the networking page for more information.

  • config.vm.post_up_message (string) - A message to show after vagrant up. This will be shown to the user and is useful for containing instructions such as how to access various components of the development environment.

  • config.vm.provider - Configures provider-specific configuration, which is used to modify settings which are specific to a certain provider. If the provider you are configuring does not exist or is not setup on the system of the person who runs vagrant up, Vagrant will ignore this configuration block. This allows a Vagrantfile that is configured for many providers to be shared among a group of people who may not have all the same providers installed.

  • config.vm.provision - Configures provisioners on the machine, so that software can be automatically installed and configured when the machine is created. Please see the page on provisioners for more information on how this setting works.

  • config.vm.synced_folder - Configures synced folders on the machine, so that folders on your host machine can be synced to and from the guest machine. Please see the page on synced folders for more information on how this setting works.

  • config.vm.usable_port_range (range) - A range of ports Vagrant can use for handling port collisions and such. Defaults to 2200..2250.
