Vagrant as you may know is one of the hottest tools in Devops for provisioning consistent development environments.
In this tutorial we will show how to provision a CentOS 7 box with Vagrant as well as the relevant support libraries for your development environment.
You will need to install the following on your local machine:
In this example I am using a Mac / OSx but you can find the relevant install instructions on their websites linked above.
On Mac you can also use Homebrew as follows:
brew cask install virtualbox brew cask install vagrant
Provision a Box
Use vagrant’s command line tool to provision your box as follows:
vagrant init centos/7; vagrant up --provider virtualbox
This command will make the Centos 7 box resource available to your local vagrant and add a Vagrant file to your local directory. View the contents:
and you will see something like this:
# -*- 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://atlas.hashicorp.com/search. config.vm.box = "centos/7" # 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 If you disable this, then # boxes will only be checked for updates when the user runs # `vagrant box outdated`.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. # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies # such as FTP and Heroku are also available. See the documentation at # https://docs.vagrantup.com/v2/push/atlas.html for more information. # config.push.define "atlas" do |push| # push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME" # end # Enable provisioning with a shell script. Additional provisioners such as # Puppet, Chef, Ansible, Salt, and Docker 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
Connect with your new box using secure shell:
You should now be on the box andsee a vagrant command prompt as follows:
you are now ready to start having fun!
