docker - 使用 traefik 将 ssl 路由到不同 docker 上的不同服务器

Question

我对此一窍不通，但在阅读了一些好的指南后，我遇到了以下问题......

我在 Ubuntu 上设置了一个家庭服务器，使用 docker 为不同的应用程序运行容器； plex、我的世界、portainer 和 traefik。我已经成功地设置了带有反向代理的 traefik，https，带有 lets encrypt 和 duckdns.org 的 ssl 路由。

从昨天开始，我已经为我的家庭自动化设置了一个带有 hass.io 的 RaspberryPi。要让 hass.io 连接到我的 Alexa 帐户，我需要它是 https，因为我已经使用 traefik 来证明我与服务器的连接......我想我也可以使用它......

但我无法让它工作。我如何设置 traefik 以便它也可以处理我服务器上 docker 之外的服务器？`

来 self 的 docker-compose.yaml

#traefik networks block, to set up reverse proxy
networks:

和我的 traefik.toml

#debug = true

logLevel = "ERROR" #DEBUG, INFO, WARN, ERROR, FATAL, PANIC
InsecureSkipVerify = true
defaultEntryPoints = ["https", "http"]

# WEB interface of Traefik - it will show web page with overview of frontend an$
[api]
  entryPoint = "traefik"
  dashboard = true
  address = ":8080"

# Force HTTPS
[entryPoints]
  [entryPoints.http]
  address = ":80"
    [entryPoints.http.redirect]
    entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]

[file]
  watch = true
  filename = "/etc/traefik/rules.toml"

# Let's encrypt configuration
[acme]
email = "john.doe@notreal.com" #any email id will work
storage="/etc/traefik/acme/acme.json"
entryPoint = "https"
acmeLogging=true
onDemand = false #create certificate when container is created
[acme.dnsChallenge]
  provider = "duckdns"
  delayBeforeCheck = 300
[[acme.domains]]
   main = "notmine.duckdns.org"
[[acme.domains]]
   main = "*.notmine.duckdns.org"

# Connection to docker host system (docker.sock)
[docker]
endpoint = "unix:///var/run/docker.sock"
domain = "notmine.duckdns.org"
watch = true
# This will hide all docker containers that don't have explicitly
# set label to "enable"
exposedbydefault = false

以上是工作代码，我只是想不出如何进行调整而不破坏一切...

正如我所说，这很棘手，菜鸟，但可以通过向 rules.toml 添加另一个域并创建一个指向另一台服务器后端的前端来解决。我使用本指南来解决问题:docs.traefik.io/v1.5/configuration/backends/file

所以我不得不将我的“非 docker 服务器”作为需要证书的新域添加到 traefik.toml

# Domain for my server on the Raspberry
[[acme.domains]]
   main = "eklandaresidenset.duckdns.org"

我还必须使用 key 编辑我的 acme.json 文件...当您重新启动 trefik 时，它应该会自行完成，但我从来没有做到这一点，所以我自己编辑了它并复制了我已经拥有的 key 在文件中。 :-)

然后我设置了我已经在 traefik.toml 中引用但尚未创建的 rules.toml，所以我这样做并添加了这个:

# Putting non-docker apps behind traefik proxy.
[backends]
  [backends.backend-anotherserver]
    [backends.backend-anotherserver.servers.anotherserver]
        url = "http://xxx.xxx.xxx.xxx:yyy" #the other servers local IP and port
        weight = 1

[frontends]
  [frontends.frontend-anotherserver]
    backend = "backend-anotherserver"
     passHostHeader = true
     passTLSCert = true
    [frontends.frontend-anotherserver.routes.domain]
        rule = "Host:anotherserver.duckdns.org"  #created another server dns-subdirectory at duckdns.org pointing to the same IP as before... just to get another header!
     [frontends.frontend-anotherserver.headers]
       SSLRedirect = true
       SSLHost = "anotherserver.duckdns.org"
       STSSeconds = 315360000
       STSIncludeSubdomains = true
       STSPreload = true
       forceSTSHeader = true
       frameDeny = true
       browserXSSFilter = true

问题解决了!
