could anyone confirm that we can put the frontend instead of pointing to gms in the ingestion recipe? ie

sink:
  type: "datahub-rest"
  config: 
    server: "<http://localhost:9002/api/gms>"

I thought i read somewhere that we can point via frontend proxy to gms, but i cant seem to find it anymore. I was trying to remove the need for a GMS ingress. however, curl to http://localhost:9002/api/gms/config doesnt work.

You CAN but only if you have Metadata Service Authentication enabled. That means you’ll have to pass an authentication token in the Authorization header also. More here:

oh, you mean

<http://localhost:9002/api/gms>"

works only if authentication is enabled?

Yes!
