【问题描述】：
我目前正在尝试将 Prometheus 适配器安装到我的 AWS EKS Kubernetes 集群中。但是，Prometheus 适配器的关联 APIService 在连接到 Prometheus 适配器时遇到问题，并且其状态未更改为“可用”
当我运行 kubectl edit apiservice custom.metrics.k8s.io 时，我得到以下信息和相应的错误消息：

另一方面，我可以使用 curl 命令从带有 kubectl 的 PC 访问服务“https://192.168.2.20:6443/apis/custom.metrics.k8s.io/v1beta1”，没有任何问题： 我得到命令
curl -k --header "Authorization: Bearer <<MYTOKEN>>" "https://172.20.44.186:443/apis/custom.metrics.k8s.io/v1beta1"
答案：
{
"kind": "APIResourceList",
"apiVersion": "v1",
"groupVersion": "custom.metrics.k8s.io/v1beta1",
"resources": [
{
"name": "namespaces/container_threads",
"singularName": "",
"namespaced": false,
"kind": "MetricValueList",
"verbs": [
"get"
]
},
{
"name": "pods/container_threads",
"singularName": "",
"namespaced": true,
"kind": "MetricValueList",
"verbs": [
"get"
]
}
]
}
但是，在适配器的日志中，我找不到任何有关来自 API 服务的请求的条目。 如何进一步分析错误并排除错误？
