5.使用 Cloudflare DNS 的 Caddy 2.x

Dockerfile(Caddy 构建器):

FROM caddy:builder AS builder
RUN xcaddy build --with github.com/caddy-dns/cloudflare

FROM caddy:latest
COPY --from=builder /usr/bin/caddy /usr/bin/caddy

构建命令:

docker build -t [YOUR-NAME]/caddycfdns .

Caddyfile(作为反向代理):

[YOUR-DOMAIN] {

  tls {
        dns cloudflare [API-KEY]
  }

#  encode gzip

#  header / {
#       # 启用 HTTP Strict Transport Security (HSTS)
#       Strict-Transport-Security "max-age=31536000;"
#       # 启用 cross-site filter (XSS) 并告诉浏览器阻止检测到的攻击
#       X-XSS-Protection "0"
#       # 禁止在框架内呈现网站 (clickjacking protection)
#       X-Frame-Options "DENY"
#       # 阻止搜索引擎编制索引(可选)
#       X-Robots-Tag "noindex, nofollow"
#       # 禁止嗅探 X-Content-Type-Options
#       X-Content-Type-Options "nosniff"
#       # 服务器名称移除
#       -Server
#       # 移除 X-Powered-By 应该不会引起问题,但最好移除 opsec
#       -X-Powered-By
#       # 移除 Last-Modified 因为 etag 具有相同的效果
#       -Last-Modified
#   }
#  # 代理到 Rocket
#  reverse_proxy vaultwarden:80 {
#       # 将真正的远程 IP 发送给 Rocket,以便 vaultwarden 可以将其
#       # 放入日志,以便 fail2ban 可以禁止正确的 IP。
#       header_up X-Real-IP {remote_host}
#  }

#  其余配置,请参阅 ”代理示例“ 部分
