Add named ports to your services that have the name '{{ .Values.linkerd.portName }}'
and linkerd will act as a proxy for them.

For example:
apiVersion: v1
kind: Service
metadata:
  name: my-http-service
spec:
  type: ClusterIP
  ports:
  - name: {{ .Values.linkerd.discoveryPortName }}
    port: 8080
  selector:
    app: my-http-service

1. Get the linkerd admin interface URL by running these commands:
{{- if contains "NodePort" .Values.service.type }}
  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "linkerd.fullname" . }})
  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
  echo http://$NODE_IP:$NODE_PORT/login
{{- else if contains "LoadBalancer" .Values.service.type }}
     NOTE: It may take a few minutes for the LoadBalancer IP to be available.
           You can watch the status of by running 'kubectl get svc --namespace= {{ .Release.Namespace }} -w {{ template "linkerd.fullname" . }}'
  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "linkerd.fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
  echo http://$SERVICE_IP:9990
{{- else if contains "ClusterIP"  .Values.service.type }}
  export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "linkerd.fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
  echo "Visit http://127.0.0.1:9990 to use your application"
  kubectl port-forward --namespace {{ .Release.Namespace }} $POD_NAME 9990:9990 4140:4140
{{- end }}
