1.首先優化ingress-controller

通過 Helm 安裝 Nginx Ingress 的預設關聯配置對映例項名稱為 nginx-ingress-controller，使用者可以通過修改資源物件 Deployment/DaemonSet 例項 nginx-ingress-controller 中的引數 --configmap 自定義關聯配置對映例項的名稱。

於是參考nginx-ingress-controller的ConfigMap配置方法，這裡配置了下：

$ kubectl -n kube-system edit configmap nginx-configuration
...
apiVersion: v1
kind: ConfigMap
data:
  allow-backend-server-header: 'true'
  enable-underscores-in-headers: 'true'
  generate-request-id: 'true'
  ignore-invalid-headers: 'true'
  keep-alive: '75'
  keep-alive-requests: '1000'
  max-worker-connections: '65536'
  proxy-body-size: 80m
  proxy-connect-timeout: '10'
  reuse-port: 'true'
  server-tokens: 'false'
  ssl-redirect: 'false'
  upstream-keepalive-connections: '1000'
  upstream-keepalive-requests: '10000'
  upstream-keepalive-timeout: '60'
  worker-cpu-affinity: auto

2.參考ingress的Annotations配置方法，優化具體deployment.yml裡的ingress 配置

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-connect-timeout: "20"
    nginx.ingress.kubernetes.io/proxy-send-timeout: "20"
    nginx.ingress.kubernetes.io/proxy-read-timeout: "20"
    nginx.ingress.kubernetes.io/connection-proxy-header: "keep-alive"
    nginx.ingress.kubernetes.io/proxy-http-version: "1.1"
    nginx.ingress.kubernetes.io/proxy-body-size: 80m
