问题描述
我们正在使用公开的Nginx Ingress控制器在GKE上运行，该控制器暴露在由Kubernetes自动配置的TCP负载均衡器下.
We are running on GKE using a public-facing Nginx Ingress Controller exposed under a TCP Load Balancer which is automatically configured by Kubernetes.
问题在于，我们的请求中有0.05％的状态码为499(Nginx唯一的状态码，表示客户端已取消).我们的P99延迟平均总是低于100毫秒.
The problem is that 0.05% of our requests have status code 499 (An Nginx unique status code which means that the client cancelled). Our P99 Latency on average is always below 100ms.
推荐答案
按照 .
As per DerSkythe's answer.
我的问题通过在配置映射中添加以下内容来解决.
My problem is solved by adding the following in the config map.
apiVersion: v1
kind: ConfigMap
data:
http-snippet: |
proxy_ignore_client_abort on;
请参见 http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_ignore_client_abort
启用此功能后，我的499错误几乎为零！
After turning this on, I have almost zero 499 errors!
如果您遇到相同的问题，我强烈建议尝试此配置.
I highly recommend trying this configuration if you are encountering the same problem.
