    transport fastcgi
	}
}

example.com {
	root * /var/www
	file_server

# 定义片段
(redirect) {
	@http {
		protocol http
	}
	redir @http https://{host}{uri}
}

  respond "Yahaha! You found {args.0}!"
}

# 引用片段

重写 header 到 path

  • abc-dev.domain.co -> abc/def/{uri}
@parseHost header_regexp parsedHost Host ^([a-z0-9]+)-([a-z0-9]+)\.domain\.co$
root @parseHost /opt/serve/{re.parsedHost.2}/stages/{re.parsedHost.1}
  • abc.builds.wener.me -> abc/{uri}
    • http.request.host.labels 从 0 开始
*.builds.wener.me {
  root * /opt/serve/builds/{http.request.host.labels.3}
  try_files {path} /index.html
  file_server
