when I try to override kubernetes config file it will not be working,
it is looking ".kube/config" file.
I have added a config file inside my project,
I want to use my customize config file.
how can I do it?
The Config
class, which you've already found, has many setters to override specific settings; but it looks you want load config from another path. In that case, you can use fromKubeconfig method.
File file = ResourceUtils.getFile("classpath:kubernetes_config");
String kubeconfigContents = Files.readString(file.toPath());
Config config = Config.fromKubeconfig(kubeconfigContents);
try (KubernetesClient k8s = new DefaultKubernetesClient(config)) {
NodeMetricsList nodeMetricsList = k8s.top().nodes().metrics();
for (NodeMetrics nodeMetrics : nodeMetricsList.getItems()) {
System.out.println(nodeMetrics.getMetadata().getName());
System.out.println(nodeMetrics.getUsage().get("cpu"));
System.out.println(nodeMetrics.getUsage().get("memory"));
}
}
