Wavefront - Kubernetes with Jaeger Configuration

This is a modified version of the configuration and installation instructions provided by Wavefront including updated kubernetes manifests. For the original documentation please follow the links below.

• Kubernetes Setup
• Jaeger Integration Setup

This has been tested with AKS.

Wavefront Proxy Deployment

Step 1: Deploy a Wavefront Proxy in Kubernetes

Download jaeger-wavefront.yaml to your system. Edit the file and set the following environment variables, container port and service port specifications.

Wavefront

env:
- name: WAVEFRONT_URL
    value: <WAVEFRONT URL>
- name: WAVEFRONT_TOKEN
    value: <WAVEFRONT TOKEN>

Wavefront Jaeger Integrations

Update the "JAEGER PORT" and "CLUSTER NAME" Environment Variables

env:
# Jaeger Tracing Environment Variable
- name: WAVEFRONT_PROXY_ARGS
    value: "--traceJaegerListenerPorts <JAEGER PORT> --traceJaegerApplicationName <CLUSTER NAME>"

Container Port

Update the container port with the same port specified in the WAVEFRONT_PROXY_ARGS environment variable.

# Jaeger Tracing Port
- containerPort: <JAEGER PORT>
  protocol: TCP

Service Port

Update the Service Port with the same Jaeger Port specified in the WAVEFRONT_PROXY_ARGS environment variable.

# Added for Jaeger Tracing
- name: jaeger
  port: <JAEGER PORT>
  targetPort: <JAEGER PORT>
  protocol: TCP

Run kubectl create -f jaeger-wavefront.yaml to deploy the proxy.

The Wavefront proxy and a wavefront-proxy service should now be running in Kubernetes.

Step 2: Deploy Kube-State Metrics Service in Kubernetes

Deploy the kube-state-metrics Service

Download kube-state.yaml to your system and run kubectl create -f kube-state.yaml.

The kube-state-metrics service should now be running on your cluster.

Steps 3: Deploy Wavefront Kubernetes Collector

Download the wavefront-collector-dir to your system:

• 0-collector-namespace.yaml
• 1-collector-cluster-role.yaml
• 2-collector-rbac.yaml
• 3-collector-service-account.yaml
• 4-collector-deployment.yaml

Edit 4-collector-deployment.yaml as follows:

Edit YOUR CLUSTER NAME to uniquely identify your Kubernetes cluster.

 command:
 - /wavefront-collector
 - --source=kubernetes.summary_api:''
 - --sink=wavefront:?proxyAddress=wavefront-proxy.default.svc.cluster.local:2878&clusterName=<YOUR CLUSTER NAME>&includeLabels=true
 - --v=2

Run kubectl create -f </path/to/wavefront-collector-dir>/ to deploy the collector on your cluster.

To verify the collector is deployed, run kubectl get pods -n wavefront-collector.

If you do not see metrics in the Kubernetes dashboard, check the logs from the collector and proxy pods.
