azure - 如何让 AzureRM 应用程序网关将 ACME .PEM 证书作为 AGW SSL 端到端配置中的 trust_root_certificates？

Question

我正在尝试通过 ACME 提供程序使用 Terraform 和 Letsencrypt 在 Azure 应用程序网关 v2.0 中创建 azurerm backend_http_settings。

我可以成功创建证书并将 .pfx 导入前端 https 监听器，acme 和 azurerm 提供商提供处理 pkcs12 所需的一切。

不幸的是，后端需要一个 .cer 文件，大概是用 base64 编码的，而不是 DER，无论我如何尝试，我都无法让它工作。我的理解是，letsencrypt .pem 文件应该可以满足此要求，但是当我尝试使用 acme 提供程序的certificate_pem 作为trusted_root_certificate 时，我收到以下错误:

Error: Error Creating/Updating Application Gateway "agw-frontproxy" (Resource Group "rg-mir"): network.ApplicationGatewaysClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="ApplicationGatewayTrustedRootCertificateInvalidData" Message="Data for certificate .../providers/Microsoft.Network/applicationGateways/agw-frontproxy/trustedRootCertificates/vnet-mir-be-cert is invalid." Details=[]

terraform 计划工作正常，当 azurerm 提供商因证书数据无效而生气时，在 terraform 应用期间会发生上述错误。我已将证书写入磁盘，它们看起来正如我所期望的那样。这是包含相关代码的代码片段:

  https_setting_name             = "${azurerm_virtual_network.vnet-mir.name}-be-tls-htst"

 }
   trusted_root_certificate {
    name = local.https_backend_cert_name
    data = acme_certificate.certificate.certificate_pem
  }
    ssl_certificate {
    name     = local.https_frontend_cert_name
    data     = acme_certificate.certificate.certificate_p12
    password = "<your password here>"
  }

   port                  = 443

  }

对我来说，唯一有效的方法是使用紧密耦合的 Windows 工具。如果您遵循以下文档，它将起作用。花了 2 天时间解决同样的问题:)
