• This project is Chef-Solo, this help to setup development base on Nodejs and Mysql

• This also includes a demo about Simple API which using Express and Mysql

What was including

• Using Chef-solo for cooking
• Using Knife-solo for initialazing, adding, editing cookbooks, roles, environment
• Using librarian-chef for managing cookbooks

Installing

• Installing librarian-chef and knife-solo

• initialazing librarian, this would create new forder with named cookbooks and a Cheffile

    librarian-chef init
  

• Adding nvm and msql cookbook to Cheffile

    cookbook 'mysql', '~> 5.5.2'
    cookbook 'nvm', '~> 0.1.0'  
  

• Initialazing knife-solo, this would create the folder structure

    knife-solo init
  

• Installing cookbooks from Cheffile

    libratian-chef install
  

• Creating an encryption key

    openssl rand -base64 512 | tr -d 'rn' > ~/.chef/encrypted_data_bag_secret
    chmod 600 ~/.chef/encrypted_data_bag_secret
  

• Adding the path of encryption key to .chef/knife.rb

    knife[:secret_file] = ".chef/encrypted_data_bag_secret"
  

• Creating a data bag, this stores the security inforamtion (ex database’s password)

     knife solo data bag create secrets myapp
  

Enter something

    {
        "id": "myapp",
         "aws_config": {
            "AWSAccessKeyId": "xxx",
            "AWSSecretKey": "xxx"
          },
      "db_config": {
        "dev": [
            {
                "name": "default",
                "mysql_root_password": "abc@123",
                "hostname": "localhost",
                "username": "root",
                "password": "abc@123",
                "database": "myqpp"
            }
        ]
      }
    }

• The encrypted data bag will be stored into data-bag/secrets/myapp.js

    {
      "id": "myapp",
      "aws_config": {
        "encrypted_data":               "RjARHBKLm0DTbHDeIB5XjTjdWovyvv5T3V9T79UyEOq4/5Km6LaZ4y7leP7/\nNLCNQaJsUZQASaAII3bzkmwamecn03q5XUp4yDzeYcCqyRhP18BnyCxYDcOm\nc0HD1xEVuOanTt5R7ppJMj3kzN02YESN4CA/+70f0Qkp6yexhVo=\n",

        "version": 1,
        "cipher": "aes-256-cbc"
      },
      "db_config": {
        "encrypted_data": "F6iPNUMY+dzao52SpQqHEWlFbGWUBMWSBAy4FinaCQ0Tbh06nDPgSdNI7qoJ\n3DjfrLBZOV1/8xD9t+SkJI3BEvW+yxCnnDPEz+iiZ8/jYJaypy/Bhrn42EC4\ni2VPb66HnVYD4Uq0pObVWzhLATXfqNZ/79I/bTdHTuhGcynDNzRNjyYEDfIF\nG9SuooNjUAduwmLotW//XxMM4uFNZ04hww==\n",

        "version": 1,
        "cipher": "aes-256-cbc"
      }
    }
  

• Creating a owner cookbook (I created myapp cookbook), this should create at site-cookbook folder

    knife cookbook create  myapp
  

• Configurating the default root password for mysql::server add site-cookbooks/myapp/attributes/default.rb (create one if this file is not existed)

    secrets = Chef::EncryptedDataBagItem.load("secrets", "myapp")
  
    default['mysql']['server_root_password']   = secrets["db_config"][node.chef_environment][0]["mysql_root_password"]
    default['mysql']['server_debian_password'] = secrets["db_config"][node.chef_environment][0]["mysql_root_password"]
    default['mysql']['server_repl_password']   = secrets["db_config"][node.chef_environment][0]["mysql_root_password"]
  

• Installing mysql and nvm and node 0.10.33 in site-cookbooks/myapp/attributes/recipes/default.rb

    include_recipe "mysql::client"
    include_recipe "mysql::server"
    include_recipe 'nvm'
  
    # install node.js v0.10.5
    nvm_install 'v0.10.33'  do
        from_source true
        alias_as_default true
        action :create
    end
  

• Creating deploy recipe, this recipe would help to deploy latest code from github to server and start/restart server

• Creating the enviroments (dev for Vagrant and prod for real server)

    kinfe evironment create dev
  

Enter something

    {
          "name": "dev",
          "description": "",
          "cookbook_versions": {

          },
          "json_class": "Chef::Environment",
          "chef_type": "environment",
          "default_attributes": {
            "myapp": {
              "root_path": "/vagrant"
            }
        },
        "override_attributes": {

        }
    }

• Creating the roles

    knife role create myapp
  

Enter something

    {
      "name": "myapp",
      "description": "",
      "json_class": "Chef::Role",
      "default_attributes": {

      },
      "override_attributes": {

      },
      "chef_type": "role",
      "run_list": [

      ],
      "env_run_lists": {
        "dev": [
          "recipe[myapp]",
          "recipe[myapp::deploy]"
        ]
      }
    }   

• Creating Vagrantfile which would use chef-solo as provision

Usage

Develop Environment using Vagrant

Notes:

• You must install Vagrant first

• Install vagrant-omnibus plugin

    vagrant plugin install vagrant-omnibus
  

Vagrant up

    vagrant up

You see something like that

    Running handlers:
    [2014-11-02T07:16:20+00:00] INFO: Running report handlers
    Running handlers complete
    [2014-11-02T07:16:20+00:00] INFO: Report handlers complete
    Chef Client finished, 30/36 resources updated in 756.082469267 seconds

Congratulation!!! You are Chef now :)
