Failed to update listener port of a Gateway CR #3111
Description
Description:
After updating the Gateway listener’s port, Envoy should listen on the new port and stop listening on the old port.
Reproduction Steps:
- Set up the Envoy gateway and Custom Resources (CRs) by following the quickstart guide. Initial setup works fine.
- Update the listener port in the Gateway Custom Resource (CR) to change it from 80 to 8001. After applying the updated Gateway CR, Envoy is not ready on either port 80 or 8001.
