Vagrant is a tool for building and managing virtual machine environments in a single workflow. With an easy-to-use workflow and focus on automation, Vagrant lowers development environment setup time, increases production parity, and makes the "works on my machine" excuse a relic of the past.
Why Vagrant?
Vagrant provides easy to configure, reproducible, and portable work environments built on top of industry-standard technology and controlled by a single consistent workflow to help maximize the productivity and flexibility of you and your team.
Run the command to init a new vagrant development environment using ubuntu 20.04.
vagrant init bento/ubuntu-20.04
The script will generate a initial Vagrantfile.
# -*- mode: ruby -*- # vi: set ft=ruby :
# All Vagrant configuration is done below. The "2" in Vagrant.configure # configures the configuration version (we support older styles for # backwards compatibility). Please don't change it unless you know what # you're doing. Vagrant.configure("2") do|config| # The most common configuration options are documented and commented below. # For a complete reference, please see the online documentation at # https://docs.vagrantup.com.
# Every Vagrant development environment requires a box. You can search for # boxes at https://vagrantcloud.com/search. config.vm.box = "bento/ubuntu-20.04"
# Disable automatic box update checking. If you disable this, then # boxes will only be checked for updates when the user runs # `vagrant box outdated`. This is not recommended. # config.vm.box_check_update = false
# Create a forwarded port mapping which allows access to a specific port # within the machine from a port on the host machine. In the example below, # accessing "localhost:8080" will access port 80 on the guest machine. # NOTE: This will enable public access to the opened port # config.vm.network "forwarded_port", guest: 80, host: 8080
# Create a forwarded port mapping which allows access to a specific port # within the machine from a port on the host machine and only allow access # via 127.0.0.1 to disable public access # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
# Create a private network, which allows host-only access to the machine # using a specific IP. # config.vm.network "private_network", ip: "192.168.33.10"
# Create a public network, which generally matched to bridged network. # Bridged networks make the machine appear as another physical device on # your network. # config.vm.network "public_network"
# Share an additional folder to the guest VM. The first argument is # the path on the host to the actual folder. The second argument is # the path on the guest to mount the folder. And the optional third # argument is a set of non-required options. # config.vm.synced_folder "../data", "/vagrant_data"
# Provider-specific configuration so you can fine-tune various # backing providers for Vagrant. These expose provider-specific options. # Example for VirtualBox: # # config.vm.provider "virtualbox" do |vb| # # Display the VirtualBox GUI when booting the machine # vb.gui = true # # # Customize the amount of memory on the VM: # vb.memory = "1024" # end # # View the documentation for the provider you are using for more # information on available options.
# Enable provisioning with a shell script. Additional provisioners such as # Ansible, Chef, Docker, Puppet and Salt are also available. Please see the # documentation for more information about their specific syntax and use. # config.vm.provision "shell", inline: <<-SHELL # apt-get update # apt-get install -y apache2 # SHELL end
Enable config.vm.synced_folder "./", "/vagrant_data" to share folder with the virtual machine.
Enable config.vm.network "forwarded_port", guest: 80, host: 8080 to expose virtual machine port 80 to localhost:8080
