Configuration simple docker-compose Traefik avec Lets Encrypt Cloudflare DNS-01 & TLS-ALPN-01 & HTTP-01 challenges

Ceci est ma configuration utilisant docker-compose pour démarrer Traefik, supportant tous les principaux fournisseurs de chiffrement. Je recommande de créer le répertoire /opt/traefik et de sauvegarder le fichier suivant comme /opt/traefik/docker-compose.yml. Cette configuration a les fournisseurs file et docker activés par défaut.

docker-compose.yml

services:
  traefik:
    image: "traefik:v3.2"
    network_mode: "host"

    environment:
      - CLOUDFLARE_EMAIL=cloudflare@mydomain.com
      - CLOUDFLARE_API_KEY=XYZABC123
    volumes:
      - "./letsencrypt:/letsencrypt"
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./conf:/etc/traefik/conf:ro"

Remplacez letsencrypt@mydomain.com par l’adresse Email à laquelle enregistrer les certificats. Assurez-vous aussi de changer

cloudflare_env_vars.yml

- CLOUDFLARE_EMAIL=cloudflare@mydomain.com
- CLOUDFLARE_API_KEY=XYZABC123

Optionnellement, créez un token Pilot et définissez-le (n’oubliez pas de dé-commenter la ligne) en utilisant

pilot_token_example.txt

# - "--pilot.token=PILOT_TOKEN_HERE"

Maintenant faisons en sorte que le service démarre automatiquement au boot (et démarrons-le maintenant) en utilisant la méthode détaillée dans générateur de service systemd docker-compose : Exécutez ce qui suit dans /opt/traefik

create_docker_compose_service.sh

curl -fsSL https://techoverflow.net/scripts/create-docker-compose-service.sh | sudo bash /dev/stdin

Nous détaillerons comment obtenir l’accès à l’API Traefik dans les posts suivants.
