Docker installation behind Traefik as Reverse Proxy

[stritti]

If you use Traefik for reverse proxy on your system you have to enhance the docker-compose.yml by following labels:

services:
  # listmonk app
  app:
   
   [...]

    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.listmonk-http.rule=Host(`example.com`)"
      - "traefik.http.routers.listmonk-http.entrypoints=web"
      - "traefik.http.routers.listmonk.rule=Host(`example.com`)"
      - "traefik.http.routers.listmonk.entrypoints=web-secure"
      - "traefik.http.routers.listmonk.tls=true"
      - "traefik.http.routers.listmonk.middlewares=secHeaders@file"
      - "traefik.http.services.listmonk.loadbalancer.server.port=9000"
      - "traefik.http.routers.listmonk.middlewares=myheader@docker"
      - "traefik.http.middlewares.myheader.headers.customFrameOptionsValue=ALLOW-FROM https://example.com"
      - "traefik.http.middlewares.myheader.headers.contentSecurityPolicy=frame-ancestors https://example.com"

The last three lines (myheader middleware) are important to get working preview of campaigns.
example.comhould be replaced by your server domain.
