DevSecOps in Practice with VMware Tanzu

By: Parth Pandit, Robert Hardt

Overview of this book

As Kubernetes (or K8s) becomes more prolific, managing large clusters at scale in a multi-cloud environment becomes more challenging – especially from a developer productivity and operational efficiency point of view. DevSecOps in Practice with VMware Tanzu addresses these challenges by automating the delivery of containerized workloads and controlling multi-cloud Kubernetes operations using Tanzu tools. This comprehensive guide begins with an overview of the VMWare Tanzu platform and discusses its tools for building useful and secure applications using the App Accelerator, Build Service, Catalog service, and API portal. Next, you’ll delve into running those applications efficiently at scale with Tanzu Kubernetes Grid and Tanzu Application Platform. As you advance, you’ll find out how to manage these applications, and control, observe, and connect them using Tanzu Mission Control, Tanzu Observability, and Tanzu Service Mesh. Finally, you’ll explore the architecture, capabilities, features, installation, configuration, implementation, and benefits of these services with the help of examples. By the end of this VMware book, you’ll have gained a thorough understanding of the VMWare Tanzu platform and be able to efficiently articulate and solve real-world business problems.

Common day-2 operations with Tanzu Application Accelerator

Congratulations! If you’ve made it this far, you have set up an API publishing and consumption model that can unlock incredible value in your enterprise software development operation.

As is usually the case in the enterprise, the hard problem is not getting something installed and configured, it’s operating it over time. Let’s look at some of these day-2 operations.

Updating an API’s route definition

Let’s say we identify a typo in an API route’s description. We’d like to be able to update that route in real time and have it propagate to the API Portal without any additional configuration. Let’s do that. Navigate to the animal-rescue app that you cloned from GitHub and open the ./backend/k8s/animal-rescue-backend-route-config.yaml file in an editor. At line 17, you’ll see a description starting with Retrieve all the anmals. Fix it so that it reads Retrieve...
