# This is a generic traefik configuration made for dockerised applications
# For an application to be visible and integrated into this traefik:
# 1. attach it to the "traefik" external network:
#        networks:
#          - traefik
#    networks:
#      traefik:
#        external: true
#
# 2. attach configuration for traefik as "labels" for the application to be exposed
#        labels:
#          - "traefik.docker.network=traefik"
#          - "traefik.enable=true"
#          - "traefik.basic.frontend.rule=Host:app.my-awesome-app.org"
#          - "traefik.basic.port=9000"
#          - "traefik.basic.protocol=http"
#          - "traefik.admin.frontend.rule=Host:admin-app.my-awesome-app.org"
#          - "traefik.admin.protocol=https"
#          - "traefik.admin.port=9443"
