Argo Rollouts is a Kubernetes controller for Progressive Delivery (blue/green and canary deployments). The controller already supports a plugin system for traffic providers (Istio, Traefik, Gateway API, etc.) and for metric providers (Prometheus, Datadog, etc.). In the latest release, the Argo team completed the trilogy by implementing support for Canary Step plugins. This extends Argo Rollouts capabilities and enriches the progressive delivery experience to accommodate a multitude of scenarios.

With Canary step plugins, you can now fully control what happens DURING the canary process and implement any custom functionality that you want within the canary steps. Did you always want to do canary gating? Deployment sync between different controllers? Custom notifications while the canary is running? Now you can!

In this talk we will see the architecture of the new plugin mechanism and explain how you can extend canary deployments with your own custom workflows.
