Chef Cookbooks

Chef also makes it possible to dynamically create and destroy servers in response to changes in load. Dive in for free with a 10-day trial of the O’Reilly learning platform—then explore all the other resources our members count on to build skills and solve problems every day. The second attribute that stood out to me, the book’s documentation. In fact, that might have been one of the very few minor negatives I found with the book — to many comments. The authors go to great lengths to thoroughly comment and document the code samples. As an IT professional, I use Chef for both Windows and Linux-based IT automation, on a regular basis.

Having separate environments for development, testing, and production is a good way to be able to develop and test cookbook updates, and other configuration changes in isolation. Chef enables you to group your nodes into separate environments so as to support an ordered development flow. And the Berksfile tells Berkshelf to read the metadata.rb file to find all the required cookbooks. Please see the following There’s more… section to find an example of a more advanced usage of the Berksfile.

Multi-Node Configuration for the Expert

…this book managed to glue all the information together…I`m using it today as a first go-to documentation page. Joining the email list for this book will allow the author to contact you to let you know about special offers and when updates for the book are available. This cronjob will run the Chef client every 15 minutes and swallow the first four retrying warning messages. https://remotemode.net/become-a-devops-engineer/chef/ This is important to avoid Cron sending out e-mails if the connection to the Chef server is a little slow and the Chef client needs a few retries. In the previous example, we specified 1,800 seconds, which results in the Chef client running every 30 minutes. Knife connects to the Chef server and deletes the node object with a given name, using the Chef server RESTful API.

What is difference between Ansible and Chef?

What are the differences between Ansible and Chef? Ansible is an open-source IT automation tool, whereas Chef is a commercial automation tool. Ansible is used for configuration management and automation of application deployment. It is good for short commands like updating of RHEL / Linux operating systems.

Specific examples like installing nginx are clear and easy to follow. At one place I worked recently, we used nginx quite extensively for internal (build & test) systems, and the nginx config file lends itself well to configuration via Chef. Incidentally, this is a good example of how you might choose certain applications (say nginx) over others (say Apache + mod_proxy) based on how easy they are to configure using Chef.

Windows PowerShell 4.0 for .NET Developers, Book Review

And it has strengths that—when combined with Ansible Automation Platform—work well to create efficiencies for many businesses. Recently, I had the opportunity to review the eBook edition of ‘Single Page Web Applications‘, by authors Michael S. Mikowski https://remotemode.net/become-a-mobile-developer/swiftui/ and Josh C. Powell, published by Manning Publications. Mikowski and Powell’s book, Single Page Web Applications, hit the market at a perfect time (release last September), and with just the right mix of timely learning opportunities for the reader.

Mikowski and Powell purposefully build a JavaScript-based SPA from the ground up, without simply plugging into a ready-made library or API. Although many readers may be heavily tied to a certain library or API, understanding how to build a SPA from the ground up is invaluable. Seasoned users of Chef will also find the ‘Managing Windows Servers with Chef’ useful. Professionals quickly master the Chef principles, and develop the means to automate their specific tasks with Chef.

DevOps Career Guide: A Comprehensive Playbook To Becoming A DevOps Engineer

Chef offers a tool named Habitat that targets software developers. The tool aims to eliminate time spent by developers rewriting the tooling to package and deploy application code, situating it within the container movement. Chef users commonly work with recipes through an integrated development environment.

  • The admin can use policy to define server types, identify environment stages, map data types and specify cookbook details.
  • Chef is an open source systems management and cloud infrastructure automation platform.
  • Mikowski and Powell purposefully build a JavaScript-based SPA from the ground up, without simply plugging into a ready-made library or API.
  • Otherwise, you need to add Berksfile.lock to your .gitignore manually.
  • Make sure you have a cookbook named my_cookbook, and the run_list of your node includes my_cookbook, as described in the Creating and using cookbooks recipe in this chapter.

Chapters 4 focuses on how PowerShell interfaces with SOAP and REST based services, web requests, and JSON. Windows Communication Foundation (WCF) based service-oriented application development has been a trend for the last few years. Being able to manage, test, and monitor SOAP and RESTful services and HTTP requests/responses is important to .NET developers. PowerShell can often quicker and easier than writing and compiling service utilities in Visual Studio, or using proprietary third-party applications. Watch the video below that will give you an in-depth understanding of the major configuration management tools ie. Ansible is open source software,and doesn’t rely on a client-server model.
