Originally, Flux was built as a monolithic “do it all” operator modeled after what Weaveworks felt that it meant to do a GitOps workflow.

(Learn how to build a CI/CD pipeline.) The differentiating factor of a GitOps pipeline is the GitOps operator. This mechanism sits between the pipeline and the infrastructure platform, acting as a middleman between them. There are multiple available operators such as: Kubernetes Operator Terraform Cloud Operator Azure Service Operator Etc. GitOps workflow Now, we’ve got a Git repository and a properly configured CI/CD pipeline. The pipeline will then inform the Git Operator, which will pick up all the modifications and the desired new state. The Git operator will then compare the state of the existing infrastructure

you try to define the sequence of steps, which unfortunately is an additional overhead on the operator. GitOps promotes a declarative approach. Every object you use in GitOps can be coded and declared to GitOps workflows. For example, when a group of configuration updates are made by a human operator, the Kubernetes orchestrator will keep applying those changes until the cluster's state is converged can also be extended and automated using Kubernetes Custom Resource Definitions (CRDs) with the operator pattern. These agents can then be used to automatically detect and apply configuration changes

and logos are property of their respective companies. Pull-based architecture requires a GitOps operator, or agent, to evaluate both the infrastructure and application configuration in the repository the Kubernetes cluster resources should automatically update based on config changes.

uses the operator pattern. This is significant on two levels: 1. It is more secure. 2. It automates complex error prone tasks like having to manually update YAML manifests. With the operator pattern
