快速构建安全的（HTTPS）本地开发环境（DNS Challenge版本）

上文使用了dev.localhost域名来进行本地开发的https配置，这次我们换用自购域名解析到127.0.0.1的形式来进行配置。

首先我们需要购买一个域名并且添加解析到127.0.0.1：

因为我们的域名指向本地而不是公网可访问的IP，所以我们需要使用DNS challenge的形式来获取tls证书。各大厂商的DNS challenge的配置方式和需要的环境变量在这里：dnsChallenge 可以找到。下面使用alidns来进行配置：

version: "3.3"

networks:
  traefik-public:
    external: true

使用docker network create traefik-public创建外部网络后使用docker-compose up便可以启动服务，访问https://traefik.bilibill.site/dashboard/#/可以看到traefik自带的webUI。
