Add Cheat Sheets for Chef, Jenkins, and Puppet
This pull request adds comprehensive cheat sheets for three key DevOps configuration management tools: Chef, Jenkins, and Puppet. These tools are widely used in automation, infrastructure management, and continuous integration/continuous deployment (CI/CD) pipelines.
Why this is valuable:
Chef, Puppet, and Jenkins are cornerstones of modern DevOps workflows, enabling efficient and reliable management of infrastructure and software delivery.
The cheat sheets provide quick yet detailed references for commands, architecture, common use cases, and best practices, helping practitioners accelerate learning and day-to-day work.
Including these cheat sheets enriches the repository’s DevOps section, making it a more complete and practical resource for developers, sysadmins, and engineers.
Sources and Quality:
All added cheat sheets come from reputable providers such as Intellipaat, which offer free, up-to-date, and well-structured content accessible without paywalls.
Highlights from the added cheat sheets:
Chef: Covers configuration management concepts, cookbook recipes, and client-server architecture details.
Puppet: Explains manifests, modules, agent-server communication, and compliance reporting capabilities.
Jenkins: Includes pipeline creation, job configuration, plugin management, and CI/CD best practices.
This update is aligned with current DevOps trends and the increasing demand for reliable infrastructure automation and deployment tools.
