Use Linkerd

What Will You Do

In this exercise,

  • You will be deploying a sample application with linkerd proxy


  • You have already provisioned or imported a Kubernetes cluster using the controller.
  • You have successfully published a linkerd addon based cluster blueprint to your cluster.

For this example, we will use a emojivoto application available at

Step 1: Download emojivoto sample application

Download the sample application provided in website.

curl --proto '=https' --tlsv1.2 -sSfL -o emojivoto.yml

Step 2: Create workload

  • Login into the Web Console and navigate to your Project as an Org Admin or Project Admin
  • Under Infrastructure (or Applications if accessed with Project Admin role), select "Namespaces" and create a new namespace called "emojivoto"
  • Next in the Wizard, in the general section add the following annotation enabled and click save and go to placement.
  • Select the appropriate cluster(s) and publish the namespace.
  • Go to Applications > Workloads
  • Select "New Workload" to create a new workload called "emojivoto"
  • Ensure that you select "k8s YAML" for Package Type and select the namespace as "emojivoto"
  • Click CONTINUE to next step
  • Select Choose File and upload emojivoto.yml file downloaded earlier
  • Save and Go to Placement
  • In the Placement step, select the cluster(s) that you would like to deploy the application
  • Publish the emojivoto workload to the selected cluster(s)

Step 3: Verify deployment

You can optionally verify whether the correct resources have been created on the cluster.

  • First, we will verify the pod status
kubectl get po -n emojivoto
NAME                        READY   STATUS    RESTARTS   AGE
emoji-56c95cbfd-ct6x7       2/2     Running   0          47m
vote-bot-84f555bcc9-nvsfh   2/2     Running   0          47m
voting-86c68ddd5-q7z9s      2/2     Running   0          47m
web-865b89955c-2vbfm        2/2     Running   0          47m
  • Then, we will verify linkerd-proxy is attached to each of the pods.
kubectl get pods --all-namespaces -o jsonpath='{range .items[*]}{"\n"}{}{":\t"}{range .spec.containers[*]}{.image}{", "}{end}{end}'

web-865b89955c-2vbfm:,, %

You can see that all the pods have a linkerd proxy attached. You can also check this from Rafay console -> cluster resources

emojivoto sidecar


Congratulations! You successfully deployed an application with Linkerd sidecar injection.
