How To Manage Remote Servers with Ansible
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. The topics that it covers include how to: - Become familiar with configuration management tools and processes, and the benefits of using them to manage your infrastructure. - 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. - Build inventory files and organize your servers into groups to selectively control how and where Ansible commands are run. - Run Ad Hoc commands to execute individual tasks on one, or multiple remote servers. - Package individual commands into Playbooks that you can use to automate the provisioning of m ...

GitOps and Kubernetes
GitOps and Kubernetes introduces a radical idea - managing your infrastructure with the same Git pull requests you use to manage your codebase. In this in-depth tutorial, you'll learn to operate infrastructures based on powerful-but-complex technologies such as Kubernetes with the same Git version control tools most developers use daily. With these GitOps techniques and best practices, you'll accelerate application development without compromising on security, easily roll back infrastructure changes, and seamlessly introduce new team members to your automation process. With GitOps you use the Git version control system to organize and manage your infrastructure just like any other codebase. It's an excellent model for applications deployed as containers and pods on Kubernetes. GitOps and Kubernetes teaches you how to use Git and the GitOps methodology to manage a Kubernetes cluster. The book interleaves theory with practice, presenting core Ops concepts alongside easy-to-implemen ...

React Hooks in Action
Build stylish, slick, and speedy-to-load user interfaces in React without writing custom classes. React Hooks are a new category of functions that help you to manage state, lifecycle, and side effects within functional components. React Hooks in Action teaches you to use pre-built hooks like useState, useReducer and useEffect to build your own hooks. Your code will be more reusable, require less boilerplate, and you'll instantly be a more effective React developer. Get started with React Hooks and you'll soon have code that's better organized and easier to maintain. React Hooks are targeted JavaScript functions that let you reuse and share functionality across components. Use them to split components into smaller functions, manage state and side effects, and access React features without classes - all without having to rearrange your component hierarchy. React Hooks in Action teaches you to write fast and reusable React components using Hooks. You'll start by learning to create c ...

Convolutional Neural Networks with Swift for Tensorflow
Dive into and apply practical machine learning and dataset categorization techniques while learning Tensorflow and deep learning. This book uses convolutional neural networks to do image recognition all in the familiar and easy to work with Swift language. It begins with a basic machine learning overview and then ramps up to neural networks and convolutions and how they work. Using Swift and Tensorflow, you'll perform data augmentation, build and train large networks, and build networks for mobile devices. You'll also cover cloud training and the network you build can categorize greyscale data, such as mnist, to large scale modern approaches that can categorize large datasets, such as imagenet. Convolutional Neural Networks with Swift for Tensorflow uses a simple approach that adds progressive layers of complexity until you have arrived at the current state of the art for this field. ...
