无法使用 @kubernetes/client-node 获取集群内的所有作业

Question

I am using "@kubernetes/client-node" to access kubernetes server API. I can get Namespaces and Pods from default using:


const k8s = require('@kubernetes/client-node');

const kc = new k8s.KubeConfig();
kc.loadFromDefault();

const k8sApi = kc.makeApiClient(k8s.CoreV1Api);

k8sApi.listNamespace().then((res) => {  // or using listAllNamespacedPods
    console.log(res.body);
});



but when i am using kc.loadFromFile('pathToKubeConfigFile'), it is unable to read it



import { KubeConfig, CoreV1Api } from '@kubernetes/client-node';

const kc = new KubeConfig();
kc.loadFromFile('./config/k8sConfig.yaml');

const k8sApi = kc.makeApiClient(CoreV1Api);

k8sApi.listPodForAllNamespaces().then((res) => {
    console.log(res.body);
});

我需要返回所有活动作业，例如部署、pod 和服务。 任何人都可以建议我如何实现它。

Answer 1

您必须传递 Kube 配置文件位置而不是任何 YAML 文件

const { KubeConfig } = require('kubernetes-client')
const kubeconfig = new KubeConfig()
kubeconfig.loadFromFile('~/some/path')
const Request = require('kubernetes-client/backends/request')

const backend = new Request({ kubeconfig })
const client = new Client({ backend, version: '1.13' })

但是，如果您计划在 K8s 集群上运行 POD 或容器，您也可以使用： kc.loadFromCluster();

如果您想传递任何 YAML 并将这些更改应用于集群，您可以使用
