![]() ![]() Let's create a file called site.yml in the same folder as our Vagrantfile. Essentially, it will log in to servers that we specify using 'ssh' and run commands on them. To automate the steps for deploying an app to a virtual machine, we will use Ansible. Note that having the ansible.verbose option enabled will instruct Vagrant to show the full ansible-playbook command used behind the scene. This will re-run the playbook against the existing VM. To re-run a playbook on an existing VM, just run: It downloads the Ubuntu image that we specified as the config.vm.box value and create our server as a virtual machine. Let's start the VM, and run the provisioning playbook (on the first VM startup): Vagrant runs the provisioner once the virtual machine has booted and is ready for SSH access. Notice the config.vm.provision section that refers to an Ansible playbook called playbook.yml in the same directory as the Vagrantfile. ![]() An access from outside devices to this IP address is not available as the network interface is private to our host machine. The guest is assigned an IP address of 192.168.33.15 and our host machine is able to access it on that IP. # to upgrade instead of disabling the requirement below.Ĭonfig.vm.network "private_network", ip: "192.168.33.15"Ĭonfig.vm.provision "ansible" do |ansible|Ī private network is created by VirtualBox between our host machine and the guest machine. # Although versions 1.6.x should behave very similarly, it is recommended # This guide is optimized for Vagrant 1.7 and above. ![]() The first step once we've installed Vagrant is to create a Vagrantfile and customize it to use the Ansible provisioner to manage a single machine: The controlling machine deploys modules to nodes using SSH protocol and these modules are stored temporarily on remote nodes and communicate with the Ansible machine through a JSON connection over the standard output. The location of nodes are specified by controlling machine through its inventory.Īnsible can interact with clients through either command line tools or through its configuration scripts called Playbooks. In other words, the controlling machine, where Ansible is installed and clients (nodes) are managed by this controlling machine over SSH. So, any computer that you can administer through SSH, we can also administer through Ansible. Ansible is agent-less which means no need of any agent installation on remote nodes, so with Ansible, there are no any background daemons or programs are executing for Ansible.Īnsible does not require any additional software to be installed on the client computers since Ansible communicates over normal SSH channels in order to retrieve information from remote machines, issue commands, and copy files. We installed Vagrant and VirtualBox in VirtualBox and Vagrant.Īmong popular configuration management tools such as Chef, Puppet, Salt, and Ansible, we chose Ansible because it has a much smaller overhead to get started. In this tutorial, we'll go through the stages of setting up a Vagrant configuration for a virtual machine, and how to provision the virtual machine using Ansible playbooks. Any developer can pickup a project and start working on it with little work with the same environment as everyone else. Once a virtual machine is generated and a provisioner is ready, we can quickly start a development environment on our machine without having to worry about finding, installing, and configuring project dependencies. In this tutorial, we'll use Ansible for the configuration. Fortunately, Vagrant is easily integrates with existing provisioners such as Chef, Puppet, and Ansible. So, it's up to us to handle the installation and configuration of the packages we want to work. Though Vagrant handles the generation and basic imaging of virtual machines to form isolated development environments, it doesn't do the provisioning of these virtual machines. Vagrant is a tool to manage virtual machine environments, and allows us to configure and use reproducible work environments on top of various virtualization and cloud platforms. In this tutorial, we'll install our Flask app into a virtual machine with Vagrant using Ansible. ![]()
