我正在 "Sequence contains no elements error" 而 运行 Azure DevOps 服务中的构建管道部署云服务（经典）

Question

我已经创建了一个 Azure 经典类型的服务连接。有什么我想念的吗？

然后我使用这个 Azure 经典服务连接将云服务部署到 Azure。

通过下面的报错信息，问题就很明显了。喜欢这张图

##[error]Sequence contains no elements

##[error]There was an error with the Azure credentials used for the deployment.

你需要通过下面的脚本获取$cred。（有一些限制，更多细节，请阅读相关帖子。）

$username = "**.com"
$password = "***"
$secstr = New-Object -TypeName System.Security.SecureString
$password.ToCharArray() | ForEach-Object {$secstr.AppendChar($_)}
$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist $username, $secstr
Add-AzureRmAccount -Credential $cred

Answer 2

##[error]There was an error with the Azure credentials used for the deployment.

您可以更改为使用 Certificate Based 作为验证方法。

要使用 Certificate Based 方法，您可以使用以下脚本创建 .cer 文件。

$cert = New-SelfSignedCertificate -DnsName yourdomain.cloudapp.net -CertStoreLocation "cert:\LocalMachine\My" -KeyLength 2048 -KeySpec "KeyExchange"
$password = ConvertTo-SecureString -String "your-password" -Force -AsPlainText
Export-PfxCertificate -Cert $cert -FilePath ".\my-cert-file.pfx" -Password $password
Export-Certificate -Type CERT -Cert $cert -FilePath .\my-cert-file.cer

那么你可以得到 upload certificate with the management portal.

同时，您可以通过.cer文件获得Public密钥。

此密钥用于服务连接。
