This is where automated provisioning comes in. Once you have your VMs defined, you can obviously then do whatever you want with them, but as soon as you issue a ‘vagrant destroy’ command any changes will be lost. This network is created and destroyed along with the vagrant guests.Īgain, the network config can be specified for all guests, or per guest as shown in the public network example above. This will create a new network in libvirt, usually named something like “vagrant-private-dhcp” – you can see this with the command sudo virsh net-list while the VM is running. If you’re creating multiple guests you can put the network configuration in the vm namespace, and even allocate IPs based on iteration too:Ĭonfig.vm.network "private_network", ip: "192.168.50.4" If you wish to assign a static IP address, you can add one to the end of the network declaration: config.vm.network “public_network”, ip: “192.168.0.1” This will use DHCP to obtain a network address.

To configure a public network, add config.vm.network “public_network” to your Vagrantfile. As Vagrant is not designed to be secure, you should be aware of any vulnerabilities and take steps to protect against them. This creates a network card for the Vagrant VM which connects to your host network, and will therefore be visible to all machines on that network. In addition to this, anyone on your network can access these ports if they know your IP address, so that’s something you should be aware of. If you then add multiple machines the complexity can really become too much. Obviously for more complex configurations this might not be ideal, as you need to specify every single port you want to forward. If you need to use a UDP port, simply add, protocol: “udp” to the end of that line (notice that comma which should come immediately after the second port number).

This listens to port 8080 on your local machine and forwards connections to port 80 on the Vagrant machine. This uses a simple format like most Vagrant config: config.vm.network “forwarded_port”, guest: 80, host: 8080 The simplest change to default networking is port forwarding. If you use dhcp for your guests, you can find the individual IP addresses with the virsh net-dhcp-list command: sudo virsh net-dhcp-leases vagrant-libvirt Port Forwarding The network is named “vagrant-libvirt” and can be seen either in the Virtual Networks tab of virt-manager’s connection details or by issuing a sudo virsh net-list command. This is automated and will always be present even if you define your own networks. The vagrant-libvirt plugin creates a network for the guests to use.

There are a number of configuration options available which allow you to interact with your VMs in various ways. If you create more than one VM then you must use the VM name to identify which one you wish to connect to – vagrant ssh vmname. Vagrant generally creates its own network for VM access, and you use this with ‘vagrant ssh’. This uses a combination of multiple machine calls and a small loop to build 4 VMs with a single ‘vagrant up’ command. In this case the provider is libvirt, and the specific config looks like this:Ĭonfig.vm.define "loadbal", primary: true do |loadbal|Ĭonfig.vm.define "db", primary: true do |db| They can be found at Īlso in this section you can configure provider-specific options. There are many options here, and a read of the documentation pages is strongly recommended.

The config structure is broken down into namespaces:Ĭonfig.vm – modify the configuration of the machine(s) that Vagrant manages.Ĭonfig.ssh – for configuring how Vagrant will access your machine over SSH.Ĭonfig.winrm – configuring how Vagrant will access your Windows guest over WinRM.Ĭonfig.winssh – the WinSSH communicator is built specifically for the Windows native port of OpenSSH.Ĭonfig.vagrant – modify the behavior of Vagrant itself.Įach line in a namespace begins with the word ‘config’: Unless you need to use the older version simply stick with the latest. The “2” represents the version of Vagrant, and is currently either 1 or 2.
