Making GitOps is the practice of deploying applications by using Git Operations only (and not clicking UI buttons). The paradigm already existed in one form or another but was officially named as ​“GitOps” configuration changes). ● It puts unnecessary strain on the CI system that has to check/rebuild/unit test each individual branch. Also, if you have a large number of environments, handling multiple

deployment (CI/CD) [1.2]? As a matter of fact, GitOps unifies a collection of different topics in automation, application delivery, infrastructure management, and security. In this chapter, I will go through linear, basing each stage on previous ones. That’s why the term commonly used for the CI/CD build/test/deploy process is a pipeline. It can provide integration, delivery, and deployment in a continuous automated tests). Continuous deploy- ment supersedes continuous delivery and is now seen as full DevOps automation. Where does GitOps fit in? GitOps doesn’t replace CI/CD, but participates in it. While traditional

reflected in the corresponding state of the associated infrastructure and applications through automation. GitOps is a natural evolution of Agile and DevOps methodologies What is GitOps? 3 Why GitOps to provision an environment The application behaves different in production than it did in test Environments are all manually configured (“pets vs. cattle”) Production deployments have declared and Kubernetes scheduler makes it happen ● GitOps in traditional environments requires automation/scripting, declarative environment minimizes or eliminates this need ● Declarations are yaml

benefits GitOps brings to Kubernetes. INCREASED SPEED AND PRODUCTIVITY Continuous deployment automation with integrated feedback and control loops speeds up your deployment frequency. Declarative allow developers to use familiar workflows, reducing the time it takes to spin up new development, test environments, or deploy new features to a cluster. Teams can ship more changes per day, and this have the following properties that make them perfect for GitOps-style deployment workflows: • Automation: Kubernetes provides a built-in mechanism for automating the deployments.

and applies them to infrastructure automation. Whereas DevOps is the practice of automating the software development lifecycle, GitOps contributes to the automation of infrastructure. This includes version relies on CI/CD tools like Jenkins to deploy code changes from the Git repository but lacks the automation benefits of pull-based deployments.

alongside purpose-built software agents (the backbone of the Weave Kubernetes Platform) and the automation already built into Kubernetes. But this increase in deployment velocity needn’t mean relinquishing productivity Mean time to deployment is reduced significantly, thanks to continuous deployment automation and an integrated feedback control loop. The results are transformative: teams can ship 30-100
