The text discusses the challenges of deploying microservice-based applications with Kubernetes and how GitOps can address these issues. GitOps is a declarative approach to continuous delivery that uses version control to manage infrastructure and applications in a centralized repository. It aims to bring familiar developer workflows to infrastructure management, providing a single source of truth for managing both application code and infrastructure. The text explains how GitOps works in practice, including the use of CI/CD tools such as Argo CD and Flux, and how it can help promote releases across environments by enabling automated promotion criteria and visualization of different application instances. It also introduces best practices for implementing GitOps in a Kubernetes environment, including the use of version control, continuous monitoring, and visibility into deployment processes.
