使用 Lets Encrypt Cloudflare DNS-01 & TLS-ALPN-01 & HTTP-01 挑战的简单 Traefik docker-compose 设置

English Deutsch 简体中文

这是我使用 docker-compose 启动 Traefik 的设置，支持所有主要加密提供者。我建议创建 /opt/traefik 目录并将以下文件保存为 /opt/traefik/docker-compose.yml。此配置默认启用 file 和 docker 提供者。

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.web.http.redirections.entryPoint.scheme=https"
      - "--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"

将 letsencrypt@mydomain.com 替换为注册证书的电子邮件地址。还要确保更改

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

可选地，创建 Pilot 令牌并设置它（不要忘记取消该行的注释）使用

pilot_token_example.txt
# - "--pilot.token=PILOT_TOKEN_HERE"

现在让我们使用docker-compose systemd .service 生成器中详细说明的方法使服务在启动时自动启动（并立即启动它）：在 /opt/traefik 中运行以下命令

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

我们将在后续文章中详细介绍如何访问 Traefik API。
