Listeners define how traffic enters the service
A listener describes the port, protocol, and forwarding behavior used by the load balancer. It is the layer that turns a public or internal endpoint into an actual application path.Listener design questions
- Which ports should accept traffic
- Which protocols the service needs
- Whether TLS should terminate at the load balancer
- Which backend group should receive that traffic
Good listener habits
- Keep listener configuration aligned with the application deployment model.
- Review listener rules when domains, certificates, or backend ports change.
- Avoid leaving old listeners active after migrations or cutovers.
