kubernetes - Traefik Ingress (Kubernetes) 没有收到 letsencrypt 证书

Question

我已经使用 let'sencrypt ACME 配置了 Traefik(helm chart)，但我没有收到任何证书。 Traefik Ingress 在端口 80 和 443 上暴露给互联网。

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"

Ingress 使用 Traefik 作为 IngressClass

        ],
        "secretName": "cert" // without is also not working
      }
    ],
    "rules": [
      {
        "host": "domain.com",
        "http": {
          "paths": [
            {
              "backend": {
                "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 质询。 dns-01 不是选项，因为我的 DNS 提供商没有 API。

您如何将 letsencrypt 配置注入(inject)您的 traefik Ingress 服务/守护进程？

Traefik 没有在 Kubernetes Ingress 文档中正式提供 letsencrypt。但这是一个 good guide .寻找“外部 Traefik 入口 Controller ”，您需要一个 kv 后端来存储您的证书。

你也可以试试cert-manager与 Traefik 配合使用。
