Repository: envoyproxy/gateway

Issue:
Graceful shutdown is not working as expected with default setup.
*Description*:
I'm working on implementing envoy-gateway as a replacement for our nginx controller.  I have some basic tests, a pod that returns a json block when hit an endpoint.  Using K6 as a testing sweet. I set up the following test.

```js
import http from 'k6/http';
import { sleep } from 'k6';

export const options = {
  stages: [
    { duration: '2m', target: 50 }, // ramp-up to 50 users
    { duration: '6m', target: 50 }, // stay at 50 users
    { duration: '2m', target: 0 },  // ramp-down to 0 users
  ],
};

export default function () {
  http.get(<url>/);
  sleep(1);
}
````

When I run this test and start a rollout restart of the envoy pods. I get the following errors

```sh

```

When I do this on nginx I do not get these errors. 

I added these to my custom proxy config and it seemed to fix the issue
``sh
shutdown:
    drainTimeout: 600s
    minDrainDuration: 60s
```
However there's no documentation on this. I happened to find it with kube-explain

I'm on v1.0.1
>Any extra documentation required to understand the issue.


Discussion:
@arkodg: @davem-git which L3/L4 load balancer are you using ? have you setup health checks ?@davem-git: I'm hosted in azure and gcp. Those test ended with the similar results on both clouds @arkodg: you'll need to setup health checks on the load balancer so they can stop routing to the envoy that is shutting down (draining), the first step when shutting dowm is failing health checks so the LB can route newer connections to a newer envoy pod
* either use the global one in envoy (`/ready` on port 19001)
* or a listener specific one (only available on v1.1) https://gateway.envoyproxy.io/docs/api/extension_types/#healthchecksettings@davem-git: How are these set? @davem-git: any documentation? envoy gateway stands up these load balancers. I see I can set annotations, but I don't see any annotations for health checks for gcp. @arkodg: I do see some health check info for 
* Azure
https://cloud-provider-azure.sigs.k8s.io/topics/loadbalancer/#custom-load-balancer-health-probe
https://cloud-provider-azure.sigs.k8s.io/topics/loadbalancer/#loadbalancer-annotations
* AWS
https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.3/guide/service/annotations/#health-check
@arkodg: hey @davem-git we just merged https://github.com/envoyproxy/gateway/pull/4021 that should help you with graceful shutdown on GKE with the default settings (no settings), you can try it out by using the `v0.0.0-latest` tag of. the helm chart@arkodg: hey @davem-git did you get a chance to try this out ? @davem-git: I've looked around and haven't found those settings for all of our cloud providers. I will test it out on azure today. So far though adding those settings I listed above seemed to have helped from my testing @arkodg: @davem-git with #4021 (which is now available with `v0.0.0-latest`) you may not need explicit health checks because we've reduced the time to detect failure for the envoy endpoints@ncsham: hey @arkodg  , just a basic doubt

is there no need for adding pod readiness gates on namespace where envoy proxies are running(proxies receiving traffic via nlb or alb) like for eg. on eks with aws-load-balancer-controller running,  ref: https://kubernetes-sigs.github.io/aws-load-balancer-controller/latest/deploy/pod_readiness_gate/ @davem-git: I tried testing this, The health checks failed to work. Envoy-proxy didn't function. I reverted @arkodg: > hey @arkodg , just a basic doubt

@ncsham afaik the controller is reading the endpoint slices of the service from the API server and will detect any endpoints that are down (whose `readinessProbe` has failed) and shouldnt route to them@github-actions: This issue has been automatically marked as stale because it has not had activity in the last 30 days.@davem-git: This is no longer an issue the past few upgrades have gone smoothly no interuptions

+
+1. Delete `BackendTLSPolicy` CRD (and resources):
