Argo Rollouts

Jan 1, 0001

Definition

Argo Rollouts is a Kubernetes controller and set of CRDs (Custom Resource Definitions) that provide advanced deployment capabilities such as blue-green deployments, canary releases, and progressive delivery strategies. It enhances the Kubernetes native deployment mechanisms by allowing more control over the rollout process, enabling features like automated analysis, traffic shaping, and rollback capabilities.
