AWS App Mesh Controller For K8s

AWS App Mesh Controller For K8s is a controller to help manage App Mesh resources for a Kubernetes cluster. The controller watches custom resources for changes and reflects those changes into the App Mesh API. It is accompanied by the deployment of three custom resource definitions (CRDs): meshes, virtualnodes, and virtualservices. These map to App Mesh API objects which the controller manages for you.

Getting started

• Install using steps under install.md
• Follow the walkthroughs under aws-app-mesh-examples, e.g. howto-k8s-fargate, howto-k8s-retry-policy.

Custom Resource Examples

First, create a Mesh resource, which will trigger the controller to create a Mesh via the App Mesh API. Then, define VirtualServices for each application that you want to route traffic to, and finally create VirtualNodes for each Deployment that will make up that Application.

Mesh

apiVersion: appmesh.k8s.aws/v1beta1
kind: Mesh
metadata:
  name: my-mesh

Virtual Node

apiVersion: appmesh.k8s.aws/v1beta1
kind: VirtualNode
metadata:
  name: my-app-a
  namespace: prod
spec:
  meshName: my-mesh
  listeners:
    - portMapping:
        port: 9080
        protocol: http
  serviceDiscovery:
    dns:
      hostName: my-app-a.prod.svc.cluster.local

    - virtualService:
        virtualServiceName: my-svc-a

Virtual Service

apiVersion: appmesh.k8s.aws/v1beta1
kind: VirtualService
