VAGRANT+PUPPET

= TRUE


Who, Me?

Mikke Schirén
Developer at Wunderkraut Sweden
(former actor, journalist, whatever)

Worked with Drupal since 4.7

d.o: MiSc , Twitter: mikkdroid

advanced

because

it's simple

WE NEED A

CONTROLLED

DEVELOPMENT

ENVIRONMENT


So WHY THE

NEED FOR VAGRANT

AND PUPPET?

MOST COMMON DRUPAL

DEVELOPMENT ENVIRONMENT

(I'm guessing here...)

MOST COMMON DRUPAL

PRODUCTION
ENVIRONMENT

(That we know for a fact)


AND THAT'S NO PROBLEM,

OR?

DEVELOPMENT ENVIRONMENT SHOULD BE LIKE PRODUCTION

AND IT SHOULD

BE EASY TO SETUP

NODEONE STORY


What we had before

One Virtual machine that should fit

all projects and developers,

the Virtualnode.

NODEONE STORY

Problem

Developers fixing their VMs so it fitted them
(updated php version, mysql, special vhost entries etc.),

OR

Developers developed locally  because it was to much work to get the virtualnode to work.
(For a while we even had an internal project - "Problem with local enviroment")


SOLUTION


Easy to set-up local environment

  • Vagrant
  • Plus provisioner(s)

VAGRANT

Vagrant is free and open-source software for creating and configuring virtual development environments. (Wikipedia)


Supports Virtualbox, VMWare,  Amazon EC2 etc.

Written in Ruby.


AND A PROVISIONER

Puppet, CHEF, ANSIBLE, SALT, DOCKER?

PUPPET

  • We are using on production servers to control them
  • We had better knowledge in Puppet than Chef
  • We could reuse what we are using for production

VAGRANTFILE

 Vagrant.configure("2")  do |config|
    # Every Vagrant virtual environment requires a box to build off of.
    config.vm.box = "precise64"
    config.vm.synced_folder '.', '/vagrant', :id => 'vagrant-root', :disabled => true
    # The url from where the 'config.vm.box' box will be fetched if it
    # doesn't already exist on the user's system.
    config.vm.box_url = "http://files.vagrantup.com/precise64.box"


VAGRANTFILE

    # Assign this VM to a host only network IP, allowing you to access it
    # via the IP.
    config.vm.network :private_network, ip: "192.168.50.91"
    config.vm.hostname = "marvin.dev.com"

    config.vm.provider "virtualbox" do |v|
        v.name = config.vm.hostname
        v.customize ["modifyvm", :id, "--memory", "2048"]
        v.customize ["modifyvm", :id, "--cpus", "1"]
    end

VAGRANTFILE

 # Provisioning settings.
     config.vm.provision :puppet do |puppet|
       puppet.facter = {
        'drupal_root' => '/srv/www/marvin/web'
       }
       puppet.manifests_path = "./"
       puppet.manifest_file = "manifests/manifest.pp"
       puppet.module_path = "./manifests/modules"
     end

    # The path to the platform
    config.vm.synced_folder "./", "/srv/www/marvin", :nfs => true
end

VAGRANTFILE - PROVISION SCRIPT

config.vm.provision :shell do |shell|
  shell.inline = "drush dl drush-7.x-5.9 -y"
end
Some extra provision could be done with shell scripting
inside the virtualmachine.

VAGRANTFILE - PROVISION SCRIPT

config.vm.provision :shell do |shell|
  shell.path = "script.sh"
end


[script.sh]
#!/bin/bash
if [ ! -d foo ]; then
  mkdir foo
fi

VAGRANTFILE - PROVISION SCRIPT

And whatever you could do with a script, like:

  • Create database

  • Add ssh-keys

  • Download databasedumps

  • Etc.



But better to use...

PUPPET manifest

class { 'systools': }
class { 'apache':
    port => 8081
}
class { 'php':
  development => true
}
class { 'drush': }
class { 'varnish': }
class { 'phpmyadmin': }
class { 'postfix': }
class { 'memcached':
  max_memory => '30%',
}


MANIFEST.PP

class { 'mysql':
  local_only     => true,
  hostname => $fqdn
}
apache::vhost { "drupal":
  document_root => $drupal_root
}

AND THE PUPPET MODULES


Like


apache  drush  jetty  memcached  mysql  php  phpmyadmin  postfix  solr  systools  varnish


And whatever you need to have.

EXAMPLE - PHP MODULE

 class php (
  $packages = [
    'php5',
    'php5-cli',
    'php5-common',
    'php5-mysql',
    'php5-gd',
    'php5-curl',
    'php5-dev',
    'php5-mcrypt',
    'php-pear',
    'php5-sqlite',
    'build-essential',
    'php5-ldap',
    'libapache2-mod-php5',
    'php5-memcache',
  ],



And DEV SETTINGS

; Development flags.
error_reporting = E_ALL | E_STRICT
display_errors = On
display_startup_errors = On
html_errors = 1
memory_limit = 256M
max_execution_time = 0

zend_extension=/usr/lib/php5/20090626/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=192.168.50.91
xdebug.remote_port=9000
xdebug.profiler_enable_trigger=1

AND MORE

  • Development environment in repository (but not the virtualbox itself)
  • Version controlled
  • No more local development
  • No more Homebrew, XAMP, WAMP. etc.

NO MORE

"It worked in my environment!"




(Or not so much of it)
