# Introduction
|
|
|
|
[Flagger](https://github.com/weaveworks/flagger) is a **Kubernetes** operator that automates the promotion of canary
|
|
deployments using **Istio**, **Linkerd**, **App Mesh**, **NGINX** or **Gloo** routing for traffic shifting and **Prometheus** metrics for canary analysis.
|
|
The canary analysis can be extended with webhooks for running system integration/acceptance tests, load tests, or any other custom validation.
|
|
|
|
Flagger implements a control loop that gradually shifts traffic to the canary while measuring key performance
|
|
indicators like HTTP requests success rate, requests average duration and pods health.
|
|
Based on analysis of the **KPIs** a canary is promoted or aborted, and the analysis result is published to **Slack** or **MS Teams**.
|
|
|
|
|
|
|
|
Flagger can be configured with Kubernetes custom resources and is compatible with
|
|
any CI/CD solutions made for Kubernetes. Since Flagger is declarative and reacts to Kubernetes events,
|
|
it can be used in **GitOps** pipelines together with Weave Flux or JenkinsX.
