What is Chef? Tutorial

Chef is well-suited for cloud environments as it can manage both data centers and cloud environments. It provides a consistent approach to infrastructure configuration, regardless of whether your systems are on-premise or in the cloud. Assume you are a DevOps engineer managing a large web application that runs on multiple servers in the cloud. The application components include a web server, a database server, and a load balancer. Each component has its configuration requirements; manually managing these can be time-consuming and error-prone.

• DevOps is a combination of “development” (Dev) and “operations” (Ops), with the goal to break down the traditional barriers between both teams.
• A) Use the SSL_CERT_FILE environment variable to specify the location for the SSL certificate authority (CA) bundle that is used by the chef-client.
• Implement Continuous Integration and Deployment (CI/CD) for your Chef cookbooks.
• Nodes are managed by Chef and each node is configured by installing Chef-Client on it.

Chef server is the central hub for storing all the data needed for configuration of the nodes. The Chef Workstation is the host accountable for modifying cookbooks and configuration data. The workstation forwards cookbooks and configuration data to the Chef server. Chef had shown a promising rise with its growth to 37% in 2019 from 36% in 2018. Therefore, training and certification in chef can fetch promising salaries and job roles in the DevOps landscape.

What’s your career objective in your role as a DevOps engineer?

A certification in your resume also acts as an add-on and increases your chances of getting selected. Test Kitchen gives the ability for using different virtualization providers for creating a container or virtual machine instances locally. Both the workstation and the cloud are preferable options for creation of instances using the Test Kitchen. In the fourth week of the course, we'll learn the concepts of Chef-client and Chef-server in a detailed manner. Y the end of this week, we'll be able to implement the installation of Chef Development Kit on Chef workstation. Integrating your infrastructure on the cloud has a lot of implications for the company.

• Answer) Use the apt_package resource to manage packages on Debian and Ubuntu platforms.
• In the second week of this course, we'll learn about Chef DevOps and explore how Chef can help in DevOps Culture.
• Chef enables you to deploy software and applications across your entire infrastructure using a few lines of code and some clicks on buttons.
• The information from the workstations is pushed on to the Chef server.
• Automate testing of your cookbooks with tools like ChefSpec and Test Kitchen.
• This is probably the trickiest question that you might face in the interview.

Talk about your leadership skills to handle and motivate the team to solve problems together. Talk about CI, release management, and other tools to keep interdisciplinary projects on track. Demonstrate as much as you can, a clear understanding of both the environments chef certification devops including the key tools. My passion is breaking down the barriers and building and improving processes, so that the engineering and operations teams work better and smarter. It’s an opportunity to be involved in the entire delivery system from start to finish.
