【Azure APIM】解决APIM Self-hosted Gateway在AKS上，最开始访问时候遇见的404问题

问题描述

根据APIM官方文档，创建Self-hosted 网关在AKS中( 使用 YAML 将自承载网关部署到 Kubernetes ：https://docs.azure.cn/zh-cn/api-management/how-to-deploy-self-hosted-gateway-kubernetes)，但是访问AKS中Services的Endpoint，得到的确实 404页面。

{
    "statusCode": 404,
    "message": "Resource not found"
}

访问截图：

查看AKS POD的日志，也是显示404 错误
