Kanary - Automated and Integrated Canary Testing Using CRD and an Operator
summary
Kanary is a CRD-based Operator that runs canary tests entirely inside Kubernetes, using Prometheus queries (PromQL), Istio for traffic when available, HPA support, and a kubectl plugin to generate canary YAML. It spawns a temporary deployment and service, runs live/test/shadow traffic, validates via PromQL, HTTP probes or label/watch, can run several canaries concurrently, automatically fails or triggers a rolling update on success, and works in the demo; multi-component app canaries are not yet supported.
