10 pull requests each time you do a release. ● 10 Git repositories. This means that you need to write your own solution that copies commits between the repositories (or uses Pull Requests between them) GitOps by definition is powered by Pull requests on a repository that contains your manifests. And in most cases, a human needs to look and approve these pull requests. This means that practicing GitOps GitOps involves at least some manual steps for handling these Pull requests. In theory, one could practice Continuous Deployment while still adopting GitOps by fully automating the Pull request part

entire system in Git means that your development team uses familiar Git-based workflows and pull requests to deploy both application and infrastructure changes to Kubernetes. With the entire state declarative application stacks. Every developer on your team is familiar with Git and can make pull requests. Now, they can use Git to accelerate and simplify application deployments to Kubernetes as well applications. With Git as the central hub for your automated CI/CD pipelines, developers can make pull requests to accelerate and simplify application and infrastructure deployments to Kubernetes. In the

developers do not need to learn to use new tools. They can work in a world they know, using pull requests to accelerate deployment and operations tasks. The benefits for development teams include increased developers access to a GitOps-based platform, they can use familiar tools and workflows (like pull requests) to optimize their efficiency. And because security and compliance are baked into the process

also use the same workflow to make infrastructure changes by creating issues, and reviewing pull requests. GitOps allows you to roll back any kind of change made in your cluster.

each change is tracked in a new version without altering previous versions (except if the user requests a change explicitly, an extreme and rare event).
