Service Meshes Available


Linkerd Dashboard

Introduction to Linkerd Dashboard

The Dashboard provides a clickable user interface for administration of Linkerd. The Dashboard provides measurements of success rate, requests/second and latency for services on the mesh. Run the Linkerd Dashboard, by executing:

1linkerd dashboard &

This command port-forwards from your local system to the linkerd-web service. You can also expose the dashboard using Kubernetes ingress, which we will see later in this section.

Since Linkerd's control plane components have the Linkerd proxy sidecarred, you can examine statistics of the traffic you are generating by looking at the dashboard. Execute:

1linkerd -n linkerd top deploy/linkerd-web

Exposing the dashboard

Instead of using linkerd dashboard & every time you'd like to see what's going on, you can expose the dashboard via an ingress. We will use the Nginx ingress, which we had deployed and used in Lab 3.

We will be applying Nginx ingress-traffic rule with basic authentication protocol

1apiVersion: v1
2kind: Secret
3type: Opaque
5 name: web-ingress-auth
6 namespace: linkerd
8 auth: YWRtaW46JGFwcjEkbjdDdTZnSGwkRTQ3b2dmN0NPOE5SWWpFakJPa1dNLgoK
10apiVersion: extensions/v1beta1
11kind: Ingress
13 name: web-ingress
14 namespace: linkerd
15 annotations:
16 "nginx"
17 $service_name.$namespace.svc.cluster.local:8084
18 |
19 proxy_set_header Origin "";
20 proxy_hide_header l5d-remote-ip;
21 proxy_hide_header l5d-server-id;
22 basic
23 web-ingress-auth
24 "Authentication Required"
26 rules:
27 - host:
28 http:
29 paths:
30 - backend:
31 serviceName: linkerd-web
32 servicePort: 8084

This exposes the dashboard at and protects it with basic auth with credentials admin,admin.

From here you may need to modify your resolv.conf to add to localhost or use an alternative approach in order to see the dashboard deployment. We will not cover this in the workshop.

Tools exposed by dashboard

Linkerd dashboard exposes various CLI tools which may come handy while you debug your application running on mesh.

Mainly there are three tools which Linkerd exposes as an extension to it's CLI commands


This will show the “golden” metrics for each deployment:

  1. Success rates
  2. Request rates
  3. Latency distribution percentiles
