Simple Traefik docker-compose setup s Lets Encrypt Cloudflare DNS-01 & TLS-ALPN-01 & HTTP-01 challenges

Toto je můj setup pomocí docker-compose pro spuštění Traefik, podporující všechny major encryption providers. Doporučuji vytvořit /opt/traefik adresář a uložit následující soubor jako /opt/traefik/docker-compose.yml. Tento config má file a docker providers povolené by default.

docker-compose.yml

services:
  traefik:
    image: "traefik:v3.2"
    network_mode: "host"
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--providers.file.directory=/etc/traefik/conf"
      - "--providers.file.watch=true"
      - "--entrypoints.web.address=:80"
      - "--entryPoints.web.http.redirections.entryPoint.to=websecure"

      - "--entrypoints.websecure.address=:443"
      - "--entryPoints.websecure.http3"
      - "--entryPoints.websecure.http3.advertisedport=443"
      - "--log.level=info"
      - "--serversTransport.insecureSkipVerify=true"

    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"

Nahraďte letsencrypt@mydomain.com Email adresou, na kterou registrovat certifikáty. Také se ujistěte, že změníte

cloudflare_env_vars.yml

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

Volitelně vytvořte Pilot token a nastavte ho (nezapomeňte odkomentovat řádek) pomocí

pilot_token_example.txt

# - "--pilot.token=PILOT_TOKEN_HERE"

Nyní udělejte službu autostart při bootu (a spusťte ji hned) pomocí metody detailované v docker-compose systemd .service generátor: Spusťte následující v /opt/traefik

create_docker_compose_service.sh

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

Budeme detailovat, jak získat přístup k Traefik API v followup příspěvcích.
