disable events?

[tooptoop4]

What would you like to be added?

looking at kubectl events I see things like "message": "Started container bla" with "userAgent": "kubelet" and "involvedObject" "kind": "Pod"

is there any config option to prevent these events being sent?

Why is this needed?

etcd can fill up

kube-apiserver default event ttl is 1h. So etcd will not be filled up by events unless the recent 1 hour events is with a too large amount.

`--event-ttl` duration     Default: 1h0m0s
 Amount of time to retain events.

Another solution is to use separated etcd for events. https://openai.com/index/scaling-kubernetes-to-2500-nodes/ openai blog also include the etcd-servers-overrides flag usage. With this solution, events are saved separately.

--etcd-servers-overrides strings

  | Per-resource etcd servers overrides, comma separated. The individual override format: group/resource#servers, where servers are URLs, semicolon separated. Note that this applies only to resources compiled into this server binary.

@pacoxu can i put ttl as 0? really not interested in the events

[pacoxu]

You may set it to a quite small duration IIUC.

Zero means no TTL, not expire immediately.
