Managing Load Balancer Listeners

This topic is part of the setup and maintenance of a load balancer. For more Load Balancing information about managing load balancers, see Managing a Load Balancer.

Warning

Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

Required IAM Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a An IAM document that specifies who has what type of access to your resources. It is used in different ways: to mean an individual statement written in the policy language; to mean a collection of statements in a single, named "policy" document (which has an Oracle Cloud ID (OCID) assigned to it); and to mean the overall body of policies your organization uses to control access to resources. written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which A collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization. you should work in.

For administrators: For a typical policy that gives access to load balancers and their components, see Let network admins manage load balancers.

Also, be aware that a policy statement with inspect load-balancers gives the specified group the ability to see all information about the load balancers. For more information, see Details for Load Balancing.

If you're new to policies, see Getting Started with Policies and Common Policies.

Working with Listeners

A listener is a logical entity that checks for incoming traffic on the load balancer's IP address.

To handle TCP, HTTP, and HTTPS traffic, you must configure at least one listener per traffic type.

When you create a listener, you must ensure that your VCN's security rules allow the listener to accept traffic.

Tip

To accommodate high-volume traffic, Oracle strongly recommends that you use stateless security rules for your load balancer subnets.

You can have one SSL certificate bundle per listener. You can configure two listeners, one each for ports 443 and 8443, and associate SSL certificate bundles with each listener. For more information about SSL certificates for load balancers, see Managing SSL Certificates.

Using the API
