【问题描述】：

Traefik.toml

defaultEntryPoints = ["http","https"]

[web]
address = ":8080"

[entryPoints]
  [entryPoints.http]
  address = ":80"
  [entryPoints.http.auth.forward]
  address = "http://forward-oauth:4181"
    [entryPoints.http.redirect]
      entryPoint = "https"
  [entryPoints.https]
  address = ":443"
    [entryPoints.https.tls]
[docker]
endpoint="unix:///var/run/docker.sock"
domain="docker.localhost"
watch=true
exposedByDefault = false

[acme]
email = "tim@tim.com"
storage = "acme.json"
caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
entryPoint = "https"
[acme.dnsChallenge]
provider = "namecheap"
delayBeforeCheck = 0

[[acme.domains]]
  main = "*.tim.com"
  sans = ["timelfelt.com"]

[file]

[backends]
  [backends.backend1]
    [backends.backend1.servers.server1]
       url = "http://192.168.192.116"

[frontends]
  [frontends.frontend1]
      backend = "backend1"
      passHostHeader = true
      [frontends.frontend1.routes.adfs]
          rule = "Host:adfs.blah.com"

我在 Traefik docker 日志中收到一条错误消息：

time="2018-11-10T06:29:28Z" level=error msg="Unable to get ACME certificate for domain \".tim.com,tim.com\" : 无法生成通配符域 \".tim.com,tim.com\" 的 ACME 提供商中的证书：ACME 需要 DNSChallenge"

namecheap API 和用户名都在主机上设置。 80 和 443 也可用。

【问题讨论】：

标签： docker dns traefik

【解决方案1】：

错误ACME needs a DNSChallenge 是在未定义 DNS 质询配置时出现的。

ACME 配置是静态配置的一部分，因此更改此部分时需要停止并重新启动 Traefik。
