What happened?

I tried to deploy k8s provider with provider name as kubernetes.

apiVersion: pkg.crossplane.io/v1
kind: Provider
metadata:
  name: kubernetes
spec:
  package: xpkg.upbound.io/crossplane-contrib/provider-kubernetes:v0.9.0
  runtimeConfigRef:
    apiVersion: pkg.crossplane.io/v1beta1
    kind: DeploymentRuntimeConfig
    name: kubernetes-provider

[swapnil@bharshankar crossplane]$ kubectl get providers.pkg
NAME         INSTALLED   HEALTHY   PACKAGE                                                         AGE

[swapnil@bharshankar crossplane]$ kubectl get pods -n crossplane-system

[swapnil@bharshankar crossplane]$ kubectl get svc -n crossplane-system

[swapnil@bharshankar crossplane]$

It showing below error in kubernetes-fd7ab5be249e-64969bb97d-97dcs pod.

How can we reproduce it?

install provider with name kubernetes

What environment did it happen in?

Crossplane version: 1.14.5

Provider deployments use the package name as the service name by default https://github.com/crossplane/crossplane/blob/master/internal/controller/pkg/revision/runtime.go#L267. Having a service named "kubernetes" shades the apiserver, and makes it so the provider can't start. This is not specific to provider-kubernetes. If you really want the provider to be named "kubernetes", you need to use the DeploymentRuntimeConfig to set the service name to something else:

apiVersion: pkg.crossplane.io/v1beta1
kind: DeploymentRuntimeConfig
metadata:
  name: kubernetes-provider
spec:
  serviceTemplate:
    metadata:
      name: something-other-than-kubernetes
