Traefik through Docker

Traefik through Docker Compose seems to be a much cleaner way than manually installing and configuring Nginx, like I used to do earlier.

traefik.yaml:

entryPoints:
  web:
    address: ":80"
    http:
      redirections:
        entryPoint:
          to: websecure
  websecure:
    address: ":443"

providers:
  docker: {}

certificatesResolvers:
  myresolver:
    acme:
      email: you@example.com
      storage: /data/letsencrypt.json
      httpChallenge:
        entryPoint: web

And docker-compose should contain something like the following:

services:
  traefik:
    image: traefik:v2.5 # TODO: try with "latest" instead of "2.5".
    restart: unless-stopped
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "./traefik.yaml:/etc/traefik/traefik.yaml"
      - "./traefik/data:/data"
      - "/var/run/docker.sock:/var/run/docker.sock"

  some-web-service-that-needs-a-reverse-proxy:
    # ...
    labels:
      - "traefik.http.routers.photoprism.rule=Host(`example.com`)"
      - "traefik.http.routers.photoprism.tls=true"
      - "traefik.http.routers.photoprism.tls.certresolver=myresolver"
