Hi everyone, I'm trying to use the controller API to create tenants and assign them brokers and servers but running into some issues. All of our broker and server instances are created with a "DefaultTenant" tag and when I make a POST request to /tenants I end up with a 500 error with message "Failed to allocate broker instances to Tag" due to not having enough untagged instances. Is there a way to create the instances without the "DefaultTenant" tag? I've tried manually changing the tag to "untagged" using the /instances endpoint per this page in the docs but I'm still running into the same issue. It works ok if I just use the /instances endpoint to update the tag but it feels like a hack doing it that way. Can someone advise on whether I'm missing a step and/or the best approach please? Thanks

Using the update endpoint is a legit way. But if you want to do it with the create ending, try updating the tag to ""

Hey @User, thank you so much for getting back to me! I tried

pinotControllerClient.updateInstanceTags("Broker_172.17.0.3_8000", Map.of("instanceTags", List.of("")));

And got the following:

[400 Bad Request] during [PUT] to [<http://localhost:55387/instances/Broker_172.17.0.3_8000/updateTags?instanceTags>] [PinotControllerClient#updateInstanceTags(String,Map)]: [{"code":400,"error":"Must provide tags to update"}]

I see. Will check that out. We should allow empty tagging. In the meantime, please use the update API. It is stable and an acceptable way to achieve what you want

Thank you, I really appreciate that! Just out of curiosity, are all servers/brokers/minions created with the tag "DefaultTenant" by default or can we create them without tags? For context, we're setting up our pinot cluster in kubernetes

yes, just dug that up
