GitOps is rapidly gaining popularity to extend the scope of DevOps further to include application infrastructure. In this article, we will have a look at GitOps and how to leverage it for delivering cloud-native underlying infrastructure of an application. It utilizes Git as the source code management tool for managing the infrastructure code. In other words, GitOps is an evaluation of infrastructure as code and and DevOps practices which uses Git as the single source of truth for provisioning infrastructure declaratively. The term GitOps was confined by Weaveworks in 2017 and was primarily aimed at managing Kubernetes

It works by using Git as a source of truth for declarative infrastructure and applications. Automated CI/CD pipelines roll out changes to your infrastructure when commits are pushed and approved in Git. Kubernetes is just one example of many modern cloud native tools that are “declarative” and that can be treated as code. Declarative means that configuration is guaranteed by a set of facts instead of by a back to and from Kubernetes. And even more importantly, when disaster strikes, your cluster’s infrastructure can also be dependably and quickly reproduced. ![Image](/uploads/documents/8/0/3/3/8033e374

the number of tools and systems needed to manage version control, configuration management, Infrastructure as Code, CI/CD, and observability have drastically increased. This puts an additional burden where infrastructure and application configuration changes revolve around Git, i.e., the version control ecosystem. The focus is entirely on keeping Git as a single source of truth for infrastructure and mechanism. Since Kubernetes and many other cloud-native technologies are almost entirely declarative, infrastructure definitions can be kept alongside application code in Git. Keeping your entire system in

It simplifies and standardizes the deployment and management in the cloud-native ecosystem, particularly in Kubernetes-based environments, where managing infrastructure as code is crucial.
