kubernetes nginx 入口请求 header 或 Cookie 太大

Question

我的 nginx-ingress-controller 在 ingress-nginx 中命名空间，我已将大型客户端头缓冲区设置为 4 16k , 4 32k等等。

kind: ConfigMap
apiVersion: v1
metadata:
  name: nginx-configuration
  namespace: ingress-nginx  
data:
  proxy-buffer-size: "16k"
  large-client-header-buffers: "4 16k"

当我检查 nginx-controller pod 中的配置时，我看到:

 kubectl exec -n ingress-nginx nginx-ingress-controller-65fd579494-jptxh cat /etc/nginx/nginx.conf | grep large_client_header
        large_client_header_buffers     4 16k;

所以一切似乎都配置正确，但我仍然收到错误消息 400 Bad Request
Request Header Or Cookie Too Large

Answer 1

确保请求通过的每个 nginx/ingress 都应该包含配置

入口:在配置中添加“large_client_header_buffers”

nginx:在 nginx 配置中添加 'http2_max_header_size' 'http2_max_field_size'
