普尔米:如何正确使用HorizontalPodAutoscaler

Question

我正在尝试用Pulumi为我的吊舱安装HPA v1

  new HorizontalPodAutoscaler(
    `${prefixedHPAName}`,
    {
        apiVersion: 'autoscaling/v1',
        kind: 'HorizontalPodAutoscaler',
        metadata: {
            name: 'worker',
            clusterName: 'redacted',
            namespace: namespaceName
       },
        spec: {
            maxReplicas: 3,
            minReplicas: 1,
            scaleTargetRef: {
                apiVersion: 'apps/v1',
                kind: 'Deployment',
                name: 'worker'
            },
            targetCPUUtilizationPercentage: 50,
        }
    }
  );

但我一直收到以下错误

kubernetes:autoscaling/v1:HorizontalPodAutoscaler (tushar-routex-routex-hpa):
    error: configured Kubernetes cluster is unreachable: unable to load Kubernetes client configuration from kubeconfig file: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable

有什么例子说明如何通过普鲁米为我的舱设置HPA？

Answer 1

这个问题与HPA或pulumi无关，这是kubectl/kubernetes客户端常见的问题，客户端无法找到连接到K8S API的kubectl文件。检查路径~/.kube/config中是否有配置文件，然后尝试在使用pulumi之前导出路径

export KUBECONFIG=~/.kube/config

如果您没有文件，您可以检查云提供商的文档来创建它。
