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.

Protecting cluster data using TMC

Kubernetes is widely used to run business-critical applications in production environments. In these cases, a reliable disaster recovery mechanism should be present to make regular cluster data and configuration backups and restore them in the event of data loss for any reason. Although Kubernetes is mostly used to run stateless workloads where the persistent data is stored outside the clusters in the databases, running stateful software, such as caches, queues, and databases, is also being adopted slowly. In Chapter 6, Managing Container Images with Harbor, the Harbor registry deployment used the data stores that were deployed on Kubernetes itself. That makes backing up data even more important.

So, to cover this important topic, we will learn how to make cluster backups and restore them using TMC with the following high-level steps:

  1. Configure an S3-compatible remote backup storage location.
  2. Configure a cluster to use the remote storage...
