# Short-Description: Traefik Reverse Proxy
# Description:       Traefik is an open-source reverse proxy and load balancer
#                    designed for microservices and containerized applications.
#                    It automatically discovers services and routes traffic
#                    based on defined rules. Traefik supports HTTP, HTTPS, and
#                    TCP protocols, offers automatic SSL certificate
#                    management, and provides a user-friendly dashboard for
#                    monitoring traffic and service health.
