Traefik 将域重定向到子域

Question

我想在 TLS 环境中将所有请求永久重定向到example.com和www.example.com到blog.example.com 。

我目前的配置：

traefik.toml ：

[entryPoints]
  [entryPoints.web]
    address = ":80"
    [entryPoints.web.http.redirections.entryPoint]
      to = "websecure"
      scheme = "https"

  [entryPoints.websecure]
    address = ":443"

[providers.docker]
  exposedbydefault = false
  watch = true
  network = "web"
[providers.file]
  filename = "traefik_dynamic.toml"

[certificatesResolvers.lets-encrypt.acme]
  email = "mymail@example.com"
  storage = "/letsencrypt/acme.json"
  [certificatesResolvers.lets-encrypt.acme.dnsChallenge]
    provider = "myprovider"

traefik_dynamic.toml ：

[http.middlewares] 
  [http.middlewares.goToBlog.redirectregex] 
    regex = "^https://(.*)example.com/(.*)" 
    replacement = "https://blog.example.com/$${2}"
    permanent = true
 
[http.routers] 
  [http.routers.gotoblog] 
    rule = "Host(`example.com`) || Host(`www.example.com`)" 
    entrypoints = ["websecure"] 
    middlewares = ["goToBlog"] 
    service = "noop@internal" 
    [http.routers.gotoblog.tls] 
      certResolver = "lets-encrypt"

当我尝试访问example.com时，它给了我一个 SSL 协议错误。 我的所有其他端点，包括blog.example.com都在工作。 我究竟做错了什么？

好吧，显然这与我的重定向配置无关。 似乎是 traefik / docker 中的一个小插曲，类似于 traefik 的ACME 证书超时。 只等了一天，一切都按预期进行。 只需两个小更新即可更正重定向配置。 也许有一个更优雅的解决方案。

traefik_dynamic.toml ：

[http.middlewares] 
  [http.middlewares.goToBlog.redirectregex] 
    regex = "^https://(.*)example.com/(.*)" 
    replacement = "https://blog.example.com/${2}"         # no double $$
    permanent = true
 
[http.routers] 
  [http.routers.gotoblog] 
    rule = "Host(`example.com`, `www.example.com`)"       # just an array of domains is fine, too
    entrypoints = ["websecure"] 
    middlewares = ["goToBlog"] 
    service = "noop@internal" 
    [http.routers.gotoblog.tls] 
      certResolver = "lets-encrypt"
