# Introduction
|
|
|
|
[Flagger](https://github.com/stefanprodan/flagger) is a **Kubernetes** operator that automates the promotion of canary deployments using **Istio** routing for traffic shifting and **Prometheus** metrics for canary analysis.
|
|
|
|
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 the **KPIs** analysis a canary is promoted or aborted and the analysis result is published to **Slack**.
|
|
|
|
|
|
|
|
Flagger can be configured with Kubernetes custom resources \(canaries.flagger.app kind\) 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.
