traefik-real-ip-plugin

Traefik plugin to retrieve client IPs. Supports retrieving the IP from and writing the result to arbitrary headers.

If a list or a count of trusted proxies is specified, the header is parsed with the same format as the X-Forwarded-For header (1.2.3.4, 1.2.3.5, ...). Otherwise, the entire header is parsed as an IP.

The first valid IP retrieved is written to the configured destination headers.
