Desenvolver rapidamente, criando toda a estrutura PaaS virtualizada localmente, depois de maneira rápida homologar com o cliente e subir o ambiente produção na AWS facilmente.

1. Dev Ninja
Vagrant + Virtualbox +
Chef-Solo + Git + EC2

2. Como isso pode ajudar no meu trabalho ?

3. Vagrant (v 1.5)
- Overview
- Vagrant Boxes (packer)
- Vagrantfile
- Basic commands:
● Vagrant up
● Vagrant provision
● Vagrant destroy
● Vagrant ssh
● Vagrant http share

4. VirtualBox (provider)
- Overview
- Vboxmanager

5. EC2 (Provider)
- Overview
- Tecnologias (IAM, AMI, Elastic IP, Route53)

6. Chef-Solo (Chef-repo)
- Overview
- Cookbooks

15. My Application Cookbook Attributes
# Repositorio
default["webapp"]["home"] = "/var/lib/webapp"
default["webapp"]["repo"] = "git@github.com:yrosaguiar/webappcode.git"
default["webapp"]["revision"] = "0.0.1"
# Database Config File Params

default["webapp"]["dbupdatefile"] = "/Config/webappdbupdate.sql"
# Site Config File Params

16. Vagrantfile - Virtual Box Provider
Vagrant.configure("2") do |config|
config.vm.define "webapp" do |define|
define.vm.box_url = "http://files.vagrantup.com/precise64.box"
define.vm.box = "webapp"
define.ssh.forward_agent = true
define.vm.hostname = "webapp"
define.vm.network :private_network, ip: "172.16.0.100"
# Configuration provision
define.vm.provision :chef_solo do |chef|
chef.cookbooks_path = "./cookbooks"
# Recipes
chef.add_recipe "apt"
chef.add_recipe "git"
chef.add_recipe "apache2"
chef.add_recipe "php"
chef.add_recipe "mysql"
chef.add_recipe "webapp:deploy"
chef.json.merge!({
})
end
end
end

17. Vagrantfile - AWS Provider
Vagrant.configure("2") do |config|
config.vm.provider :aws do |aws, override|
override.vm.box_url ="http://files.vagrantup.com/precise64.box"
aws.access_key_id = "YOUR AWS ACCESS KEY"
aws.secret_access_key = "YOUR AWS SECRET KEY"
aws.keypair_name = "YOUR AWS KEYPAIR NAME"
aws.ami = "ami-23d9a94a"
aws.instance_type = "m1.large"
aws.region = "us-east-1"
aws.security_groups = ["open"]
aws.user_data = File.read('ec2-setup.sh')
override.ssh.username = "vagrant"
override.ssh.private_key_path = "AWS PRIVATE KEY"
define.vm.provision :chef_solo do |chef|
chef.cookbooks_path = "../cookbooks"
# Recipes
chef.add_recipe "apt"
chef.add_recipe "git"
chef.add_recipe "apache2"
chef.add_recipe "php"
chef.add_recipe "mysql"
#chef.add_recipe "webapp:deploy"
chef.json.merge!({
} )
end
end
end

18. Override Attributes
Atributos no Vagrantfile
chef.json.merge!({
}
:mysql => {
:server_root_password => "pass123"
:bind_address => "0.0.0.0"
},
}
})
Arquivo de atributos - Ex: default.rb
default['mysql']['data_dir'] = '/var/lib/mysql'
default['mysql']['server_root_password'] = '123'
default['mysql']['packages'] = %w{ mysql-server apparmor-utils }
default['mysql']['slow_query_log'] = 1
default['mysql']['slow_query_log_file'] = '/var/log/mysql/slow.log'
default['mysql']['bind_address']= '127.0.0.1'
# Platformisms.. filesystem locations and such.
default['mysql']['basedir'] = '/usr'
default['mysql']['tmpdir'] = ['/tmp']
