How to add consul registry in istio

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!

Solution

  • 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}]"
