How to add consul registry in istio

8/31/2020

I want to add a consul registry in istio, but the istio documentation only has the pilot-discovery discovery command with the parameters:

--consulserverURL <string>
--registries <stringSlice>

But I don’t know how to write command line parameters into the configuration file, and the istio document does not describe how to do this.

Please advise, thanks!

As mentioned in istio documentation you can use

pilot-discovery discovery [flags]

Pilot is part of istiod now, so you can get your istio pods with

kubectl get pods -n istio-system

Use kubectl exec to get into your istiod container with 

kubectl exec -ti <istiod-pod-name> -c discovery -n istio-system -- /bin/bash

Use above pilot-discovery command with appropriate flags

e.g.

pilot-discovery discovery --consulserverURL="asd.x.svc:9999" --registries="{Kubernetes,Consul}"

2020-09-01T09:16:43.529136Z     info    FLAG: --registries="[{Kubernetes,Consul}]"
