A cookbook is the fundamental unit of configuration and policy distribution.
What is a Cookbook?
A cookbook is the chef-client's unit of configuration and policy distribution which defines a scenario and contains everything that is required to support it:
The chef-client uses Ruby as its reference language for its cookbooks and recipes.
What is Chef-solo?
Chef-solo is an open source version of the chef-client that allows using cookbooks with nodes without requiring access to a Chef server. chef-solo runs locally and requires that a cookbook (and any of its dependencies) be on the same physical disk as the node.
This box allows you to include legacy chef's cookbooks or recipes into your Application Catalog within ElasticBox. It downloads a Chef Cookbook's configuration files for be used by chef-solo. It's intended to customize a cookbook with its own default.rb and metadata.rb files that will define recipe's attributes and its needed dependencies.
CHEF_COOKBOOK_NAME: Name of the cookbook and its directory
CHEF_DEFAULT_RB: is the attributes file to be configured and saved into the cookbook folder (CHEF_COOKBOOK_NAME). For each cookbook, attributes in the default.rb file are loaded first. When the cookbook attributes take precedence over the default attributes, the chef-solo client will apply those new settings and values when chef-solo client run on the instance.
CHEF_METADATA_RB: Every cookbook requires a small amount of metadata stored in a file called metadata.rb that lives at the top of CHEF_COOKBOOK_NAME’s directory. The contents of the metadata.rb file provides hints to chef-solo so that cookbook is deployed correctly.
Accelerate Cloud Adoption
As you move your applications to the cloud, Chef makes your adoption path not just smooth, but fast. Migrate your workloads quickly, consistently, and at a pace that suits your needs.
Manage Multiple Cloud Environments
Take control of all your cloud environments. Chef is cloud agnostic, which means you’re free to pick the cloud providers that meet your requirements, based on features and cost.
Manage Both Data Center and Cloud Environments
Chef lets you manage all your environments. Manage Windows, Linux, AIX, and Solaris servers, whether in the cloud or on premises.
Maintain High Availability
Keep the Chef Server API available even in case of partial network or hardware failure. The Chef server can operate in a high availability configuration that provides automated load balancing and failover for stateful components in the system architecture.
This open source software is free to use.
An instance executing this box will use bash scripting to download and save the configuration of a Cookbook. Box events handle the chef-cookbook lifecycle on the instance as follows:
pre_configure event script: creates cookbook's folder and download and configure the default.rb and metadata.rb files defined in the box variables.
The box supports deploying to these linux distributions:
