| ## Flagger Add-On | ||
|
|
||
| [Flagger](https://flagger.app/) is a progressive delivery tool that automates the release process for applications running on Kubernetes. It reduces the risk of introducing a new software version in production by gradually shifting traffic to the new version while measuring metrics and running conformance tests. The Flagger add-on provisions the necessary Helm chart, and namespace to allow support for flagger in an EKS workload. | ||
|
|
||
| ## Usage | ||
|
|
||
| ```typescript | ||
| import 'source-map-support/register'; | ||
| import * as cdk from 'aws-cdk-lib'; | ||
| import * as blueprints from '@aws-quickstart/eks-blueprints'; | ||
|
|
||
| const app = new cdk.App(); | ||
|
|
||
| const addOn = new blueprints.addons.Flagger(); | ||
|
|
||
| const blueprint = blueprints.EksBlueprint.builder() | ||
| .addOns(addOn) | ||
| .build(app, 'my-stack-name'); | ||
| ``` | ||
|
|
||
| ## Functionality | ||
|
|
||
| 1. Creates the `flagger` namespace. | ||

Changed it to this: 1. Creates the 'flagger' namespace. This parameter is optional and may be provided by the user in the namespace field of your addon props. |
||
| 2. Deploys the `flagger` Helm chart into the cluster. | ||
| 3. Supports [standard helm configuration options](./index.md#standard-helm-add-on-configuration-options) | ||
|
|
||
| ## Configuration Options | ||
|
|
||
| - `prometheus`: Pass true or false if you wish to track deployment metrics via prometheus. `True by default`. | ||
| - `meshProvider`: Pass from the following enum list of meshProviderOptions. `KUBERNETES by default`. | ||
|
|
||
| ```typescript | ||
| export const enum MeshProviderOptions { | ||
| KUBERNETES = 'kubernetes', | ||
| ISTIO = 'istio', | ||
| LINKERD = 'linkerd', | ||
| APPMESH = 'appmesh', | ||
| CONTOUR = 'contour', | ||
| NGINX = 'nginx', | ||
| GLOO = 'gloo', | ||
| SKIPPER = 'skipper', | ||
| TRAEFIK = 'traefik', | ||
| OSM = 'osm' | ||
| } | ||
| ``` | ||
|
|
||
| - Example Configuration: | ||
|
|
||
| ```typescript | ||
| import * as blueprints from '@aws-quickstart/eks-blueprints'; | ||
|
|
||
| const flagger = new blueprints.addons.FlaggerAddOn(); | ||
