wait #4459

[zirain]

configmap updates to the pod take at least 30 seconds to effect in pod, increase timeout for this.

EG controller support reload configuration, rollout is unnecessary.

LGTM thanks !
would be great if you can also attach some manual testing logs to the PR

there's no more manual test, our e2e change the envoy-gateway-config during set up.
wasm http server changes catched by another e2e test, which spend me a lot of time to find out.

Ah nice !

Let's remember to delete all the rollout commands in the docs in a follow PR which we suggest when editing EnvoyGateway config
