      How To Manage Remote Servers with Ansible eBook in PDF format

      Introduction to the eBook

      This book is designed to introduce you to using Ansible to manage your servers. You’ll learn how to install and configure Ansible on a control node, and then how to use it to configure and run commands on remote servers. You’ll also learn how to collect tasks into complete Playbooks to automate server setup from start to finish.

      This book is based on the How To Manage Remote Servers with Ansible tutorial series found on DigitalOcean Community. The topics that it covers include how to:

      1. Become familiar with configuration management tools and processes, and the benefits of using them to manage your infrastructure.

      2. Install and configure Ansible on an Ubuntu 20.04 control node, ensuring that your servers are properly set up and that you are able to execute remote instructions through Ansible.

      3. Build inventory files and organize your servers into groups to selectively control how and where Ansible commands are run.

      4. Run Ad Hoc commands to execute individual tasks on one, or multiple remote servers.

      5. Package individual commands into Playbooks that you can use to automate the provisioning of multiple servers, and how to run specific sets of tasks in Playbooks using tags.

      Each chapter is usable on its own as a reference, or as part of a progressive guide to learning how to manage your servers with Ansible. If you’re familiar with a topic, or are more interested in a particular section, feel free to jump to the chapter that best suits your purpose.

      Rails on Containers eBook in PDF format

      Introduction to the eBook

      This book is designed to introduce you to using containers and Kubernetes for full-stack development. You’ll learn how to develop a full-stack application using Ruby on Rails and PostgreSQL with Sidekiq, and how to manage them all — first with Docker, then with Docker Compose, and finally with Kubernetes.

      This book is based on the Rails on Containers tutorial series found on DigitalOcean Community. The topics that it covers include how to:

      1. Get started developing an application about sharks using the Ruby on Rails framework

      2. Extend the application’s data model to incorporate user submitted information about sharks

      3. Add the Stimulus JavaScript and Bootstrap CSS frameworks to your application to create visually appealing, interactive pages

      4. Integrate Sidekiq into your application to handle asynchronous data processing

      5. Containerize your application and streamline your development workflow using Docker Compose

      6. Migrate your Docker Compose development workflow to Kubernetes, finishing with a completely cloud-native application

      Each chapter is is designed to build progressively from the first. However, if you’re familiar with a topic, or are more interested in a particular section, feel free to jump to the chapter that best suits your purpose.

      How To Code in Node.js eBook in PDF format

      Introduction to the eBook

      Node.js is a popular open-source runtime environment that can execute JavaScript outside of the browser. The Node runtime is commonly used for back-end web development, leveraging its asynchronous capabilities to create networking applications and web servers. Node is also a popular choice for building command line tools.

      In this book, you will go through exercises to learn the basics of how to code in Node.js, gaining skills that apply equally to back-end and full stack development in the process.

      By the end of this book you will be able to write programs that leverage Node’s asynchronous code execution capabilities, complete with event emitters and listeners that will respond to user actions. Along the way you will learn how to debug Node applications using the built-in debugging utilities, as well as the Chrome browser’s DevTools utilities. You will also
      learn how to write automated tests for your programs to ensure that any features that you add or change function as you expect.
