Basic Usage of Networking

Vagrant offers multiple options for how you are able to connect your guest machines to the network, but there is a standard usage pattern as well as some points common to all network configurations that are important to know.

Configuration

All networks are configured within your Vagrantfile using the config.vm.network method call. For example, the Vagrantfile below defines some port forwarding:

Vagrant.configure("2") do |config|
  # other config here

  config.vm.network "forwarded_port", guest: 80, host: 8080
end

Every network type has an identifier such as :forwarded_port in the above example. Following this is a set of configuration arguments that can differ for each network type. In the case of forwarded ports, two numeric arguments are expected: the port on the guest followed by the port on the host that the guest port can be accessed by.

Multiple Networks

Multiple networks can be defined by having multiple config.vm.network calls within the Vagrantfile. The exact meaning of this can differ for each provider, but in general the order specifies the order in which the networks are enabled.

Enabling Networks

Networks are automatically configured and enabled after they've been defined in the Vagrantfile as part of the vagrant up or vagrant reload process.
