Question

我已使用Let'sencrypt ACME配置了Traefik（舵图），但没有收到任何证书。 Traefik Ingress在端口80和443上公开了互联网。

traefik.toml

logLevel = "INFO"
InsecureSkipVerify = true
defaultEntryPoints = ["http","https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"
  compress = true
  [entryPoints.https]
  address = ":443"
  compress = true
    [entryPoints.https.tls]
      [[entryPoints.https.tls.certificates]]
      CertFile = "/ssl/tls.crt"
      KeyFile = "/ssl/tls.key"
[kubernetes]
[acme]
email = "email@email.com"
storage = "/acme/acme.json"
entryPoint = "https"
onHostRule = true
caServer = "https://acme-staging-v02.api.letsencrypt.org/directory"
acmeLogging = true
  [acme.httpChallenge]
  entryPoint = "http"
[web]
address = ":8080"

以Traefik作为IngressClass的Ingress

                "serviceName": "domain",
                "servicePort": 443
              }
            }
          ]
        }
      },
      {
        "host": "www.domain.com",
        "http": {
          "paths": [
            {
              "backend": {
                "serviceName": "www-domain",
                "servicePort": 443
              }
            }
          ]
        }
      }
    ]
  },
  "status": {
    "loadBalancer": {}
  }
}

我尝试同时使用http-01和tls-sni-01挑战。 dns-01是没有选择的，因为我的DNS提供程序没有API。

如何将letsencrypt配置注入traefik Ingress服务/守护程序集？

Traefik在Kubernetes Ingress文档上没有正式的letencrypt。但这是good guide。查找“外部Traefik入口控制器”，您需要一个kv后端来存储您的证书。

您也可以尝试与Traefik一起使用的cert-manager。

当前不建议在Kubernetes上使用对Traefik的内置ACME支持，因为设置故障转移/冗余变得很困难。正如Rico提到的那样，证书管理器是一种更好的解决方案，并且是Traefik团队目前推荐的解决方案：）

Traefik Ingress（Kubernetes）未收到letencrypt证书
