How to configure keepalive-time

[csmarvz]

Hello, does someone know if there is a way to set keepalive-time? I'd like to increase it to something more than the default 1h.

Thanks and cheers!

Hi @csmarvz, Thank you for making this discussion.

I was wondering, which keepalive-time are you talking about?
Is it the upstream one or is it for http/server/location blocks as shown here?

Hi @AlexFenlon, thanks for the quick reply! I guess it is for the http/server/location, like for the keepalive-timeout here but I'm really not an expert, it's the first time I'm touching the nginx config. I'm trying to configure it for a websocket service which should keep the connection alive more or less all the time in best case.

Thanks for your help!

Hey @csmarvz,

For NIC, snippets can be used directly on the ConfigMap or VirtualServer/VirtualServerRote and TransportServer.

Snippets allow injecting nginx config where you want it so I recommend looking in to this as you will be able to set the keepalive-time directive here.

Thanks @AlexFenlon ! Looks like it yeah. If someone else is wondering, that's how my ConfigMap looks like:

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-config
  namespace: nginx-ingress
data:
  server-snippets: |
    keepalive_time 6h;
