Kubernetes nginx入口控制器不转发带下划线的头

我遇到了一个问题，我的kubernetes nginx ingress控制器NOT转发带有下划线的头部。
我使用以下条目创建了一个名为my-release-ingress-nginx-controller的configMap。

enable-underscores-in-headers: "true"

在此之后，我通过描述nginx入口控制器pod检查了nginx.conf文件，使用此命令kubectl exec -it my-release-ingress-nginx-controller-d7648bcc8-6lfxv cat nginx.conf。在那里我发现了这个underscores_in_headers on;。即使在此切换之后，nginx仍然不会转发带有下划线的头部。
配置Map：

apiVersion: v1
kind: ConfigMap
metadata:
  name: my-release-ingress-nginx-controller
  namespace: default
data:
  enable-underscores-in-headers: "true"
  ignore-invalid-headers: "false"

ConfigMap描述：

Name:         my-release-ingress-nginx-controller
Namespace:    default

PS：我已经在AWS ec2服务器中使用minikube设置了一个单节点Kubernetes集群。此外，入口配置为部署而不是daemonset。配置的入口是来自此存储库的kubernetes入口-https://github.com/kubernetes/ingress-nginx

请试试这个

apiVersion: v1
kind: ConfigMap
data:
  enable-underscores-in-headers: "true"
  ignore-invalid-headers: "false"
metadata:
  name: nginx-configuration
  namespace: default

并将其包含在nginx-ingress-controller-deployment中

containers:
  - name: nginx-ingress-controller
    image: <YOUR NGINX INGRSS IMAGE_NAME>
    args:
      - /nginx-ingress-controller
      - --configmap=$(POD_NAMESPACE)/nginx-configuration
    env:
      - name: POD_NAME
        valueFrom:
          fieldRef:
            fieldPath: metadata.name
      - name: POD_NAMESPACE
        valueFrom:
          fieldRef:
            fieldPath: metadata.namespace

apiVersion: v1

  enable-underscores-in-headers: "true"
metadata:

  namespace: default

在标题中启用下划线
在将其添加到配置中之后，需要滚动重启以获取配置。

使用下面的menifest创建新的configmap &删除nginx控制器的pod，这基本上是使用新的configmap配置创建新的nginx控制器。

apiVersion: v1
data:
  enable-underscores-in-headers: "true"
  ignore-invalid-headers: "false"
kind: ConfigMap
metadata:
  name: my-release-ingress-nginx-controller
  namespace: default

如果有人使用ingress-nginx helm chart，解决方案是：https://github.com/kubernetes/ingress-nginx/blob/e09e40af1ad33cf748ee92502f61ec2b6f741b96/charts/ingress-nginx/templates/controller-configmap.yaml#L26
配置值：

values: |
    controller:
      config:
          enable-underscores-in-headers: "true"
          ignore-invalid-headers: "false"
          allow-snippet-annotations: "true"
