Set up automated workflows to keep systems and applications consistent globally, regardless of architecture, cloud, or container runtime Purchase of the print or Kindle book includes a free PDF eBook Key Features Automate building and modifying complex software images across multiple OSs and container engines Minimize cost by keeping your systems ready across multiple architectures, including ARM and future RISC-V processors Speed up your time to market by building and testing apps using upstream and future releases Book Description Creating machine images can be time-consuming and error-prone when done manually. HashiCorp Packer enables you to automate this process by defining the configuration in a simple, declarative syntax. This configuration is then used to create machine images for multiple environments and cloud providers. The book begins by showing you how to create your first manifest while helping you understand the available components. You'll then configure the most common built-in builder options for Packer and use runtime provisioners to reconfigure a source image for desired tasks. You'll also learn how to control logging for troubleshooting errors in complex builds and explore monitoring options for multiple logs at once. As you advance, you'll build on your initial manifest for a local application that'll easily migrate to another builder or cloud. The chapters also help you get to grips with basic container image options in different formats while scaling large builds in production. Finally, you'll develop a life cycle and retention policy for images, automate packer builds, and protect your production environment from nefarious plugins. By the end of this book, you'll be equipped to smoothen collaboration and reduce the risk of errors by creating machine images consistently and automatically based on your defined configuration. What you will learn Build and maintain consistent system images across multiple platforms Create machine images that can be used in multiple environments Write a spec for a local Packer virtual machine in JSON and HCL Build a container image with Packer in different formats Automate Packer with continuous delivery pipelines Discover how to customize Packer by writing plugins Who this book is for This book is for DevOps engineers, Cloud engineers, and teams responsible for maintaining platform and application images for enterprise private, hybrid, or multi-cloud environments. Familiarity with operating systems and virtualization concepts, with or without using a cloud provider, is a prerequisite.

Continuous delivery adds enormous value to the business and the entire software delivery lifecycle, but adopting this practice means mastering new skills typically outside of a developer’s comfort zone. In this practical book, Daniel Bryant and Abraham Marín-Pérez provide guidance to help experienced Java developers master skills such as architectural design, automated quality assurance, and application packaging and deployment on a variety of platforms. Not only will you learn how to create a comprehensive build pipeline for continually delivering effective software, but you’ll also explore how Java application architecture and deployment platforms have affected the way we rapidly and safely deliver new software to production environments. Get advice for beginning or completing your migration to continuous delivery Design architecture to enable the continuous delivery of Java applications Build application artifacts including fat JARs, virtual machine images, and operating system container (Docker) images Use continuous integration tooling like Jenkins, PMD, and find-sec-bugs to automate code quality checks Create a comprehensive build pipeline and design software to separate the deploy and release processes Explore why functional and system quality attribute testing is vital from development to delivery Learn how to effectively build and test applications locally and observe your system while it runs in production

Kubernetes has become the dominant container orchestrator, but many organizations that have recently adopted this system are still struggling to run actual production workloads. In this practical book, four software engineers from VMware bring their shared experiences running Kubernetes in production and provide insight on key challenges and best practices. The brilliance of Kubernetes is how configurable and extensible the system is, from pluggable runtimes to storage integrations. For platform engineers, software developers, infosec, network engineers, storage engineers, and others, this book examines how the path to success with Kubernetes involves a variety of technology, pattern, and abstraction considerations. With this book, you will: Understand what the path to production looks like when using Kubernetes Examine where gaps exist in your current Kubernetes strategy Learn Kubernetes's essential building blocks--and their trade-offs Understand what's involved in making Kubernetes a viable location for applications Learn better ways to navigate the cloud native landscape

The days of separate dev and ops teams are over - knowledge silos and the "throw it over the fence" culture they create are the enemy of progress. As an engineer or developer, you need to confidently own each stage of the software delivery process. This book introduces a new paradigm, BEAMOps, that helps you build, test, deploy, and debug BEAM applications. Create effective development and deployment strategies; leverage continuous improvement pipelines; and ensure environment integrity. Combine operational orchestrators such as Docker Swarm with the distribution, fault tolerance, and scalability of the BEAM, to create robust and reliable applications. BEAMOps starts by building a solid foundation for your project. On the infrastructure side, see how to use Terraform before you even start coding to automate your deployment and operations. On the project management side, we show you how to use issues and milestones to simplify tracking; you'll use this foundation as you go through the book, implementing each of the steps required to deploy a scalable Elixir application. Now that you have a foundation, you can start building. Create a Phoenix LiveView application and explore mix releases. Make your deployments reliable with Docker. Continuously improve your codebase by implementing an efficient continuous deployment/integration pipeline with GitHub Actions. Scale the Phoenix LiveView application and operate a distributed BEAM system in production using AWS EC2 nodes, AWS load balancers, and a remote Docker swarm. Recognize which application metrics should be collected and monitored, and set alerts when certain thresholds are met to ensure that your application auto-scales. Ship less code more often, and ensure it works! The pragmatic BEAMOps approach that we teach in this book - an extension of the well-known DevOps paradigm - will help you become a multidisciplinary developer who is empowered to own each stage of the software delivery process. After reading this book, you'll understand how to apply the BEAMOps principles in your daily work, creating reliable, scalable, and easy to understand applications in a cooperative team environment. What You Need: Elixir 1.16.0 (compiled with Erlang/OTP 26) Phoenix framework 1.7.0 Erlang 26.2.1 Terraform v1.7.1 Docker v20.10.22 Packer v1.9.0 Docker Compose v2.21.0 SOPS 3.8.1 Age 1.1.1 An AWS account AWS CLI v2.15.15 A GitHub account GitHub CLI v2.42.1 jq v1.7
