it can be declar- ative based on a source of truth. Based on a reconciliation loop, the GitOps controller makes changes to the cluster by deploying new instances, once those changes have been committed by the GitOps controller. What’s powerful about this method is that you no longer have to wait for the CI/CD process to finish before detecting and correcting drift. The GitOps controller acts as both containers provide an advantage. Containers Change the Game Containers represent a totally different view of continuity in your infrastructure. You make software changes not by updating an existing configuration

Deployment Pipeline GitOps implements a Kubernetes controller that listens for and synchronizes deployments to your Kubernetes cluster. The controller uses the operator pattern. This is significant instance. Weave Cloud instances are the primary workspaces for your application and provides a view onto your cluster and the application that is running on it. 1. Step through the setup screens and see several objects created in your cluster. 3. Weave Cloud is now connected to your instances. View your cluster by clicking on the Explore tab. For automated deployments and GitOps, there is one

both high-level and low-level representations. On one hand, we need a way to provide a bird’s eye view of the whole company/department deployments to all stakeholders who need an easy and understandable problem by combining these two kinds of information (git hashes and features) in a single cohesive view. You can now use the new Codefresh dashboard and correlate extra information on top of a single
