different Git branches for each environment (more on this later) and you also introduce further manual steps just for release promotion. 3. “We only have one environment.” Great for small companies, but not and approve these pull requests. This means that practicing GitOps involves at least some manual steps for handling these Pull requests. In theory, one could practice Continuous Deployment while still any human intervention. This is the ultimate form of a deployment pipeline, as it takes manual steps completely out of the equation. Using Continuous Deployment and GitOps is an open question right

The monolithic application should be split up Amazon Web Service (AWS) Weavework’s invented and honed GitOps to accelerate and automate the installation of production-grade Kubernetes.

visibility and communication between development and business teams. It also automates the manual steps that slow down application delivery. The purpose of continuous delivery is to deploy new code with that get the cluster configured with the GitOps controller. The base directory contains YAML installation configuration, while overlays contain GitOps controller config- urations. There is only one overlay

declaratively. This declarative approach is focused on the result (desired state) rather than the steps needed to achieve the required result. This declarative approach allows users to specify the end

The opposite of declarative is an imperative approach where you try to define the sequence of steps, which unfortunately is an additional overhead on the operator. GitOps promotes a declarative
