<# .SYNOPSIS Download a file to Azure .DESCRIPTION Download any file to an Azure Storage Account .PARAMETER AccountId Storage Account Name / Storage Account Id where you want to fetch the file from .PARAMETER AccessToken The token that has the needed permissions for the download action .PARAMETER SAS The SAS key that you have created for the storage account or blob container .PARAMETER Blobname Name of the container / blog inside the storage account you where the file is .PARAMETER FileName Name of the file that you want to download .PARAMETER Path Path to the folder / location you want to save the file The default path is "c:\temp\d365fo.tools" .PARAMETER GetLatest Switch to tell the cmdlet just to download the latest file from Azure regardless of name .EXAMPLE PS C:\> Invoke-D365AzureStorageDownload -AccountId "miscfiles" -AccessToken "xx508xx63817x752xx74004x30705xx92x58349x5x78f5xx34xxxxx51" -Blobname "backupfiles" -FileName "OriginalUAT.bacpac" -Path "c:\temp" Will download the "OriginalUAT.bacpac" file from the storage account and save it to "c:\temp\OriginalUAT.bacpac" .EXAMPLE PS C:\> Invoke-D365AzureStorageDownload -AccountId "miscfiles" -AccessToken "xx508xx63817x752xx74004x30705xx92x58349x5x78f5xx34xxxxx51" -Blobname "backupfiles" -Path "c:\temp" -GetLatest Will download the file with the latest modified datetime from the storage account and save it to "c:\temp\". The complete path to the file will returned as output from the cmdlet. .EXAMPLE PS C:\> $AzureParams = Get-D365ActiveAzureStorageConfig PS C:\> Invoke-D365AzureStorageDownload @AzureParams -Path "c:\temp" -GetLatest This will get the current Azure Storage Account configuration details and use them as parameters to download the latest file from an Azure Storage Account Will download the file with the latest modified datetime from the storage account and save it to "c:\temp\". The complete path to the file will returned as output from the cmdlet. .EXAMPLE PS C:\> Invoke-D365AzureStorageDownload -GetLatest This will use the default parameter values that are based on the configuration stored inside "Get-D365ActiveAzureStorageConfig". Will download the file with the latest modified datetime from the storage account and save it to "c:\temp\d365fo.tools". .EXAMPLE PS C:\> Invoke-D365AzureStorageDownload -AccountId "miscfiles" -SAS "sv2018-03-28&siunlisted&src&sigAUOpdsfpoWE976ASDhfjkasdf(5678sdfhk" -Blobname "backupfiles" -Path "c:\temp" -GetLatest Will download the file with the latest modified datetime from the storage account and save it to "c:\temp\". A SAS key is used to gain access to the container and downloading the file from it. The complete path to the file will returned as output from the cmdlet. .NOTES Tags: Azure, Azure Storage, Config, Configuration, Token, Blob, File, Files, Latest, Bacpac Author: Mötz Jensen (@Splaxi) The cmdlet supports piping and can be used in advanced scenarios.
