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.

Why Tanzu Build Service?

There are various business, technical, and security challenges in building container images for applications. This becomes even more complex when we do it at scale in a large enterprise. Let’s understand what those challenges are and how TBS addresses them.

Increasing developer productivity

As discussed, one of the most popular approaches to building container images today is using Dockerfiles. And, in most cases, the application teams are responsible for building and maintaining such Dockerfiles for their applications. These Dockerfiles contain details such as the base container operating system and its version, application bundles such as JAR files for a Java application, environment variables, and useful libraries and their versions.

JAR files

A Java ARchive (JAR) file is a package of an application containing compiled source code files, configuration files, and external libraries required by the application. A JAR file can either be a...
