Cómo configurar el tamaño del encabezado de la solicitud nginx en k8s

En términos generales, usamos el ingreso de nginx basado en los servicios abiertos de k8s, si necesitamos modificar la configuración relevante de ingreso client_header_buffer_size.

  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/proxy-body-size: 5M
    nginx.ingress.kubernetes.io/server-snippet: client_header_buffer_size 2046k;
