java - io.fabric8.kubernetes.client.KubernetesClientException：10000 MILLISECONDS 后未准备好

Question

我能够使用 kubernetes-client Java[io Fabric] 检索集群详细信息，如命名空间版本等，但无法通信或执行任何活动，如获取 pod 名称或服务名称 [kubectl get po/svc] 等。

openjdk 版本“1.8.0_292” OpenJDK 运行时环境（内部版本 1.8.0_292-b10） OpenJDK 64 位服务器 VM（内部版本 25.292-b10，混合模式）

kubernetes-client-5.5.0 -io:fabric

以下是错误，请提供任何建议：
