Un ejemplo de máquina virtual lista para PHP+Symfony2+XDebug

Home / Uncategorized / Un ejemplo de máquina virtual lista para PHP+Symfony2+XDebug

Charlando con algunos amigos desarrolladores php surgió un tema que les estaba resultando complicado, así que decidí poner mi pequeño granito de arena (para ellos y para otros que tal vez estén pasando por lo mismo).

Ya habíamos hablado del por qué usar una máquina virtual para proyectos PHP. Ya estaba claro que usar un framework es más conveniente que no usarlo (independientemente de cuál fuera) y les había comentado sobre mis herramientas favoritas de automatización (Ansible y Vagrant).

Todos estábamos de acuerdo “en la teoría”, pero a la hora de pasar a la práctica se veían algo frustrados por no poder lograr tener una máquina virtual que fuese fácil de usar y que soportara, entre otras cosas, el uso de XDebug.

Lo que te voy a mostrar a continuación son los archivos de configuración que yo usé en el último proyecto que hice en php:

El archivo playbook.yml:

Para iniciar el proyecto, basta con copiar y pegar esto en un archivo llamado Vagrantfile (en la raíz de tu proyecto):

# -*- 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 = "ubuntu/trusty64"

# 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 # `vagrant box outdated`.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.
 config.vm.network "forwarded_port", guest: 80, host: 8080

# 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 = "2048"
 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

#
 # Run Ansible from the Vagrant Host
 #
 config.vm.provision "ansible" do |ansible|
   ansible.playbook = "ansible/playbook.yml"
   ansible.verbose = "vv"
 end

# Symfony needs to be able to write to it's cache, logs and sessions directory in var/
 config.vm.synced_folder "./var", "/vagrant/var",
   :owner => 'vagrant',
   :group => 'www-data',
   :mount_options => ["dmode=777","fmode=777"]
 end

y ejecutar el comando (Obviamente, habiendo instalado Vagrant previamente…):

 vagrant up

Y comienza la magia 🙂

Un ratito después (Dependiendo de la conexión que tengas) vas a tener una máquina lista para desarrollar tu aplicación basada en Symfony2.

Y ahora… ¡a codear!
