Envoy 网关未分配地址

Question

您好，我正在尝试在 K8s 中部署 envoy-gateway。我已经创建了一个部署，如 envoy 示例 Github 存储库中所述。 部署成功，但不知何故特使没有为我分配 IP 地址。 粘贴 kubectl 描述 envoy-gateway 输出的片段。

Spec:
  Gateway Class Name:  example-gateway-class
  Listeners:
    Allowed Routes:
      Namespaces:
        From:  Same
    Name:      http

    Status:                True
    Type:                  Accepted

    Type:                  Programmed

任何帮助将不胜感激。非常感谢！！

您是在本地 K8s 集群上执行此操作吗？如果您没有 LoadBalancer（例如 MetalLB），您将不会暴露外部 IP，但您必须进行端口转发才能到达 EG。对于本地开发人员来说通常可以正常工作。
