如何測試 ClusterIssuer 求解器？

Question

我正在嘗試在 DigitalOcean 上使用 LetsEncrypt 部署帶有 SSL 證書的 Kubernetes 集群。 我按照這些說明進行操作，直到 ClusterIssuer 創建挑戰訂單之前一切正常。 然后我得到這個錯誤：

cert-manager/controller/orders "msg"="Failed to determine the list of Challenge resources needed for the Order" "error"="no configured challenge solvers can be used for this challenge" "resource_kind"="Order" "resource_name"="letsencrypt-prod-cert-458163912-1173127706"

我已經嘗試過使用 http 並嘗試配置 DigitalOcean 的dns01解析器，但都不起作用，並且出現了類似的錯誤。 該網站由 ip 和 dns 名稱直播（盡管我收到了無 ssl 證書警告）。 這是 ClusterIssuer 描述：

有沒有辦法查看求解器本身來驗證它們的配置是否正確？ 有沒有辦法鍛煉它們來證明它們有效？ 有沒有其他方法可以診斷情況是什么？ 我完全被卡住了，因為似乎沒有很多在線支持？

上面引用的方法對我有用，tls-cert 是在預期的命名空間中自動生成的，密鑰和證書都是。 為此，您應該將 nginx 負載均衡器的 IP 指向 DNS

它對我有用，acme 挑戰將得到自動測試，一旦完成，證書會將其狀態從 false 更改為 true
