Summary

This chapter provided a comprehensive overview of two important tools, OPA and Harbor, and their applications in modern DevOps workflows. OPA is a policy-as-code tool that enables organizations to manage and enforce policy decisions across their infrastructure. The chapter outlined several real-world use cases of OPA, such as API validation, authorization, and data filtering. It also covered the key features of OPA, including its flexible architecture, rich query language, and integrations with various platforms.

Harbor, on the other hand, is a cloud-native registry that provides secure storage, distribution, and management of Docker images. This chapter explained the need for Harbor in modern DevOps workflows and provided a step-by-step guide to installing Harbor with Kubernetes. A demo was also included to show how Harbor can be used to scan for vulnerabilities in Docker images, ensuring that the images used in production are secure and free from security threats.
