Steps to Reproduce the Problem

Follow this docs https://ocelot.readthedocs.io/en/latest/features/kubernetes.html

services.AddOcelot(_configuration).AddKubernetes(false); // or true

My service in k8s: devices-api.dev:10010

Config:

{
    "ReRoutes": [
        {
            "DownstreamPathTemplate": "/{everything}",
            "DownstreamScheme": "http",
            "UpstreamPathTemplate": "/devices/{everything}",
            "ServiceName": "devices-api.dev",
            "UpstreamHttpMethod": [ "Get" ]
        }
    ],
    "GlobalConfiguration": {
        "ServiceDiscoveryProvider": {
            "Namespace": "dev",
            "Type": "kube"
        }
    }
}

@neetra no, I just don’t use it. I run Ocelot in kubernetes but without AddKubernetes

Hi @mot256

If you set this setting to false you are going to have an exception at runtime 😉

Nope. Works just fine. Its without setting it to false in runtime that we get an issue…
