eni-manager

Overview ¶

Package main implements the AWS Multi-ENI Manager, which is responsible for bringing up secondary network interfaces on AWS EC2 instances.

The ENI Manager can run in two modes: 1. Polling mode: periodically checks for network interfaces that are in the DOWN state 2. Netlink subscription mode: subscribes to netlink events and reacts immediately to interface changes

When it finds interfaces that need to be brought up, it attempts to do so using either the netlink library or the 'ip' command as a fallback. This ensures that secondary ENIs attached by the controller are properly configured and ready for use.
