Chef Effortless Patterns
Chef Effortless pattern is considered one of the best practices to use Chef InSpec and Chef Infra. This pattern runs a build process and pulls down all your cookbooks and profiles. This process creates a deployable package. The package stores your cookbooks and an updated Chef Infra Client if you are working with Chef Infra. Similarly, all your profiles and an updated Chef InSpec Client are stored in the package when using Chef InSpec.
The Effortless uses the Chef Habitat for proper dependency management. You can consider Effortless as a lighter version of Habitat.
The main advantage of using this pattern instead of Habitat is the reduced amount of code. It allows us to build Chef products with relatively less knowledge and much lesser code.
At runtime, the Chef Infra activates Chef Solo Mode. It works without getting connected to the Chef Infra server. Similarly, Chef InSpec vendors all the profiles at the build time. Thus, removing the need for Chef Automate. This method reduces the load and increases system performance.
Limitations of Chef Effortless Patterns
Every feature or software has its limitations. They give good performance under some constraints. If situations exceed those constraints, then the performance downgrades. Effortless is advantageous but only under certain conditions. As good programmers, we should always consider both sides of the coin. So let us discuss the scenarios where we should avoid using Effortless.
-
Since Effortless can be considered a lighter version of Habitat, it does not perform well for deploying complex applications. You should use Chef Habitat if you are working on complex applications.
-
We cannot use the Chef Infra server with Effortless. So if you want to use features of the Infra server in your cookbooks, you must use something other than Effortless. Now consider a tree with a single root. This tree has multiple children who may have children, and so on. Every node of this tree is dependent on the parent. Bringing change in the root node will change every child node.
-
If your cookbook dependency has a nested tree-like relationship, then it is better to use something other than Effortless. The management becomes difficult.
Now let us take a quick peek at setting up Effortless’s environment and configuring it.
Effortless Environment Setup and Configuration
You can set up the environment in three easy steps:
-
First, install Chef Workstation.
-
Run the hab setup command on your workstation and configure Chef Habitat.
-
Clone Chef’s Effortless git repository.
Congratulations ninja! You have successfully set up Chef Effortless in your system.
The last thing that remains is to configure it. Follow the below steps:
-
Go to the chef_repo_pattern directory inside the effortless_config folder.
examples>effortless_config>chef_repo_pattern.
- Search the kitchen.yml file and add your system’s origin to it.
provisioner:
arguments: ["<Your Origin>", "effortless-config-baseline"]
-
Run the hab pkg build command to build your package. This statement is the part where Habitat comes in.
- Your package is built! You can now run the test kitchen to see the cookbook work.
kitchen converge base-centos
All done! Great job, Ninja! You have successfully installed and configured Chef Effortless on your system.
Frequently Asked Questions
What is a recipe in Chef?
A recipe is a group of attributes that are used to manage the Chef’s infrastructure. Recipes load whenever we run the Chef client. Recipes modify or set the state of the infrastructure.
What do you mean by a Cookbook in chef?
As the name suggests, a Cookbook is a directory of recipes. It makes sure to provide the required infrastructure for the recipes present inside it.
How was Chef started?
Adam Jacob created Chef. He made it a tool for his consulting-based company. Initially, it started with the name “marionette.” Considering the long term, which was difficult to remember, Adam changed its name to Chef.
