我会高度推荐大家看看Mike Greiling的博客文章Simplify OpsWorks开发Packer和他的github回购opsworks-vm 帮助你模拟整个opsworks堆栈，包括opsworks代理的安装，所以你也可以testing应用程序部署食谱，多层，同时有多个实例等等，这是非常令人印象深刻的。

在使用Mike Greiling的Packer Virtualbox构build之前，我已经包含了准备环境所需的所有设置。

在Ubuntu 14.04上快速启动

注意：这不能从Ubuntu虚拟机完成，因为virtualbox不支持64位机器的嵌套虚拟化。

1. 安装ChefDK
   1. mkdir /tmp/packages && cd /tmp/packages
   2. wget https://opscode-omnibus-packages.s3.amazonaws.com/ubuntu/12.04/x86_64/chefdk_0.8.1-1_amd64.deb
   3. sudo dpkg -i chefdk_0.8.0-1_amd64.deb
   4. cd /opt/chefdk/
   5. chef verify
   6. which ruby
   7. echo 'eval "$(chef shell-init bash)"' >> ~/.bash_profile && source ~/.bash_profile
2. 安装VirtualBox
   1. echo 'deb http://download.virtualbox.org/virtualbox/debian vivid contrib' > /etc/apt/sources.list.d/virtualbox.list
   2. wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -
   3. sudo apt-get update -qqy
   4. sudo apt-get install virtualbox-5.0 dkms
3. 安装Vagrant
   1. cd /tmp/packages
   2. wget https://dl.bintray.com/mitchellh/vagrant/vagrant_1.7.4_x86_64.deb
   3. sudo dpkg -i vagrant_1.7.4_x86_64.deb
   4. vagrant plugin install vagrant-berkshelf
   5. vagrant plugin install vagrant-omnibus
   6. vagrant plugin list
4. 安装Packer
   1. mkdir /opt/packer && cd /opt/packer
   2. wget https://dl.bintray.com/mitchellh/packer/packer_0.8.6_linux_amd64.zip
   3. unzip packer_0.8.6_linux_amd64.zip
   4. echo 'PATH=$PATH:/opt/packer' >> ~/.bash_profile && source ~/.bash_profile
5. 使用Packer构buildMike Greiling的opsworks-vm virtualbox映像
   1. mkdir ~/packer && cd ~/packer
   2. git clone https://github.com/pixelcog/opsworks-vm.git
   3. cd opsworks-vm
   4. rake build install
   5. 这将安装一个新的virtualbox虚拟机到〜/ .vagrant.d / boxes / ubuntu1404-opsworks /

要模拟一个opsworks实例，像这样创build一个新的Vagrantfile：

 Vagrant.configure("2") do |config| config.vm.box = "ubuntu1404-opsworks" config.vm.provision :opsworks, type: 'shell', args: 'path/to/dna.json' end 

dna.json文件path是相对于Vagrantfile设置的，应该包含任何你想发送给OpsWorks Chef的JSON数据。

例如：

 { "deploy": { "my-app": { "application_type": "php", "scm": { "scm_type": "git", "repository": "path/to/my-app" } } }, "opsworks_custom_cookbooks": { "enabled": true, "scm": { "repository": "path/to/my-cookbooks" }, "recipes": [ "recipe[opsworks_initial_setup]", "recipe[dependencies]", "recipe[mod_php5_apache2]", "recipe[deploy::default]", "recipe[deploy::php]", "recipe[my_custom_cookbook::configure]" ] } } 

要模拟多个opsworks实例并包含图层，请参阅他的AWS OpsWorks“入门”示例 ，其中包含下面的stack.json 。

Vagrantfile（用于多个实例）

 Vagrant.configure("2") do |config| config.vm.box = "ubuntu1404-opsworks" # Create the php-app layer config.vm.define "app" do |layer| layer.vm.provision "opsworks", type:"shell", args:[ 'ops/dna/stack.json', 'ops/dna/php-app.json' ] # Forward port 80 so we can see our work layer.vm.network "forwarded_port", guest: 80, host: 8080 layer.vm.network "private_network", ip: "10.10.10.10" end # Create the db-master layer config.vm.define "db" do |layer| layer.vm.provision "opsworks", type:"shell", args:[ 'ops/dna/stack.json', 'ops/dna/db-master.json' ] layer.vm.network "private_network", ip: "10.10.10.20" end end 

stack.json

 { "opsworks": { "layers": { "php-app": { "instances": { "php-app1": {"private-ip": "10.10.10.10"} } }, "db-master": { "instances": { "db-master1": {"private-ip": "10.10.10.20"} } } } }, "deploy": { "simple-php": { "application_type": "php", "document_root": "web", "scm": { "scm_type": "git", "repository": "dev/simple-php" }, "memcached": {}, "database": { "host": "10.10.10.20", "database": "simple-php", "username": "root", "password": "correcthorsebatterystaple", "reconnect": true } } }, "mysql": { "server_root_password": "correcthorsebatterystaple", "tunable": {"innodb_buffer_pool_size": "256M"} }, "opsworks_custom_cookbooks": { "enabled": true, "scm": { "repository": "ops/cookbooks" } } } 

对于那些不熟悉stream浪者的人，你只需要做一个vagrant up来启动实例。 那么你可以在本地修改你的食谱，任何改变都可以通过重新运行厨师来对付现有的无法提供vagrant provision.实例vagrant provision. 你可以做一个vagrant destroy和vagrant up到从头开始。
