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.

Unboxing Tanzu Build Service

As described previously, TBS is built on top of two main open source projects: CNB and kpack. The following figure depicts the whole packaging of TBS:

As shown in the preceding figure, kpack includes engine and CLIs, whereas CNB includes things such as Builder, buildpacks and their groups, the stack, build and run images, and the life cycle process. Additionally, there are some VMware-supplied components for additional functionalities that are bundled in TBS. Let’s understand them in detail.

Cloud-native buildpacks

The concept of CNB was derived from the concept of buildpacks in Cloud Foundry, which is another container orchestration platform for cloud-native applications. The buildpacks in Cloud Foundry have been proven a battle-tested tool for over a decade. Buildpacks in Cloud Foundry are used to scan application source code, determine application requirements...
