Argo Rollouts is a Kubernetes controller that facilitates progressive delivery by enabling canary deployments, which gradually shift traffic to new application versions to minimize disruption. This approach contrasts with blue/green deployments by incrementally redirecting a subset of live traffic, using a smart proxy or load balancer to initially send a small percentage, such as 10%, to the new version, allowing issues to be detected with minimal user impact. As confidence in the new version grows, traffic can be increased in stages, reaching full deployment if no problems arise. Argo Rollouts offers integration with networking and metric solutions for traffic splitting and automatic canary stage promotions, enhancing the deployment's resilience and reliability. The use of automation tools like Codefresh and Prometheus metrics allows for further optimization of the deployment process, enabling automatic promotion or rollback based on predefined performance thresholds, thus achieving continuous deployment. The controller's flexibility and support for multiple service configurations make it adaptable to various network setups, ensuring that deployments are both efficient and customizable.
