504 Gateway Time-out

[invokerbyxv]

I have an OCR service that receives larger files and takes longer to process.

I followed the tutorial and created ClientSettingsPolicy. It does work for Request entity too large error. But 504 Gateway Time-out still occurs.

Maybe I should set proxy_connect_timeout, proxy_read_timeout, proxy_send_timeout. But I don't know how to set them. Can anyone help me?

kubectl apply -n nginx-gateway -f - <<EOF
apiVersion: gateway.nginx.org/v1alpha1
kind: ClientSettingsPolicy
metadata:
  name: gateway-client-settings
spec:
  targetRef:
    group: gateway.networking.k8s.io
    kind: Gateway
    name: all-gateway
  body:
    maxSize: "100m"
    timeout: "10m"
  keepAlive:
    time: "10m"
    timeout:
      server: "10m"
EOF

Hi @invokerbyxv, see if you can take advantage of the SnippetsFilter API. The guide shows an example by setting some rate limiting fields, but you should be able to instead set timeout fields in this filter object to attach to your Route.

For example, here's a SnippetsFilter that you could attach to your Route:

apiVersion: gateway.nginx.org/v1alpha1
kind: SnippetsFilter
metadata:
  name: timeouts
spec:
  snippets:
    - context: http.server.location
      value: proxy_read_timeout 60s;
