• We impl'd missing functionality to identify the kube config file that contains the current-context name (not the context object, the pointer so to say):

  Lines 20 to 42 in 52ad428

  	fun getFileWithCurrentContext(): Pair<File, Config>? {
  	return io.fabric8.kubernetes.client.Config.getKubeconfigFilenames()
  	.asSequence()
  	.mapNotNull { filepath: String? ->
  	if (filepath != null) {
  	File(filepath)
  	} else {
  	null
  	}
  	}
  	.filter { file: File ->
  	file.exists()
  	&& file.isFile
  	}
  	.mapNotNull { file: File ->
  	val config = KubeConfigUtils.parseConfig(file) ?: return@mapNotNull null
  	Pair(file, config)
  	}
  	.filter { pair: Pair<File, Config> ->
  	pair.second.currentContext?.isNotEmpty() != null
  	}
  	.firstOrNull()
  	}

• given multiple kubeconfigs with competing current-context properties, the last defined property is used

fabric8io/kubernetes-client#6787 (comment) turned out to be invalid, caused by a misconfiguration in my files.
