EKS Charts

Add the EKS repository to Helm:

helm repo add eks https://aws.github.io/eks-charts

App Mesh

Create the appmesh-system namespace:

kubectl create ns appmesh-system

Apply the App Mesh CRDs:

kubectl apply -f https://raw.githubusercontent.com/aws/eks-charts/master/stable/appmesh-controller/crds/crds.yaml

Install the App Mesh CRD controller:

helm upgrade -i appmesh-controller eks/appmesh-controller \
--namespace appmesh-system

Install the App Mesh admission controller:

helm upgrade -i appmesh-inject eks/appmesh-inject \
--namespace appmesh-system \
--set mesh.create=true \
--set mesh.name=global

If you've installed the App Mesh controllers with scripts, you can switch to Helm by removing the controllers with:

# remove injector objects
kubectl delete ns appmesh-inject
kubectl delete ClusterRoleBinding aws-app-mesh-inject-binding
kubectl delete ClusterRole aws-app-mesh-inject-cr
kubectl delete  MutatingWebhookConfiguration aws-app-mesh-inject

# remove controller objects
kubectl delete ns appmesh-system
kubectl delete ClusterRoleBinding app-mesh-controller-binding
kubectl delete ClusterRole app-mesh-controller

Note that you shouldn't delete the App Mesh CRDs or the App Mesh custom resources (virtual nodes or services) in your cluster. Once you've removed the App Mesh controller and injector objects, you can proceed with the Helm installation as described above.

App Mesh add-ons

Prometheus monitoring

Install App Mesh Prometheus:

helm upgrade -i appmesh-prometheus eks/appmesh-prometheus \
--namespace appmesh-system

Access Prometheus UI on localhost:9090 with:

kubectl -n appmesh-system port-forward svc/appmesh-prometheus 9090:9090

To retain the monitoring data between chart upgrades or node restarts, you can create a PersistentVolumeClaim:

cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: prometheus
  namespace: appmesh-system
  labels:
    app.kubernetes.io/name: appmesh-prometheus
spec:
  storageClassName: gp2
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 100Gi
EOF

Install Prometheus with persistent storage:

helm upgrade -i appmesh-prometheus eks/appmesh-prometheus \
--namespace appmesh-system \
--set retention=12h \
--set persistentVolumeClaim.claimName=prometheus

Grafana

Install App Mesh Grafana:

helm upgrade -i appmesh-prometheus eks/appmesh-grafana \
--namespace appmesh-system

Grafana uses Prometheus as data source and comes with dashboards for monitoring the App Mesh control plane, Envoy data plane and Flagger canary releases.

Access Grafana on localhost:3000 with:

kubectl -n appmesh-system port-forward svc/appmesh-grafana 3000:3000

AWS X-Ray

Enable X-Ray tracing for the App Mesh data plane:

helm upgrade -i appmesh-inject eks/appmesh-inject \
--namespace appmesh-system \
--set tracing.enabled=true \
--set tracing.provider=x-ray

The above configuration will inject the AWS X-Ray daemon sidecar in each pod scheduled to run on the mesh. Note that you should restart all pods running inside the mesh after enabling tracing.

Jaeger tracing

Install App Mesh Jaeger:

helm upgrade -i appmesh-jaeger eks/appmesh-jaeger \
--namespace appmesh-system

For Jaeger persistent storage you can create a PersistentVolumeClaim and use --set persistentVolumeClaim.claimName=<PVC-CLAIM-NAME>.

Access Jaeger UI on localhost:16686 with:

kubectl -n appmesh-system port-forward svc/appmesh-jaeger 16686:16686

Enable Jaeger tracing for the App Mesh data plane:

helm upgrade -i appmesh-inject eks/appmesh-inject \
--namespace appmesh-system \
--set tracing.enabled=true \
--set tracing.provider=jaeger \
--set tracing.address=appmesh-jaeger.appmesh-system \
--set tracing.port=9411

Note that you should restart all pods running inside the mesh after enabling tracing.

Datadog tracing

Install the Datadog agent in the appmesh-system namespace and enable tracing for the App Mesh data plane:

helm upgrade -i appmesh-inject eks/appmesh-inject \
--namespace appmesh-system \
--set tracing.enabled=true \
--set tracing.provider=datadog \
--set tracing.address=datadog.appmesh-system \
--set tracing.port=8126

Note that you should restart all pods running inside the mesh after enabling tracing.
