How to download a file using BITS in a Packer provisioner?
Comment
1 / 1
To download a file using Background Intelligent Transfer Service (BITS) in a Packer provisioner, you can use a PowerShell script with the Start-BitsTransfer
cmdlet. Here's an example:
json{
"builders": [
// Your builder configuration here
],
"provisioners": [
{
"type": "powershell",
"inline": [
"$sourceUrl = 'https://example.com/file.zip'",
"$destinationPath = 'C:\\path\\to\\destination\\file.zip'",
"Start-BitsTransfer -Source $sourceUrl -Destination $destinationPath"
]
}
]
}
Explanation:
- Set the
$sourceUrl
variable to the URL of the file you want to download. Replace'https://example.com/file.zip'
with the actual download URL. - Set the
$destinationPath
variable to the path where you want to save the downloaded file. Replace'C:\path\to\destination\file.zip'
with the desired destination path. - Use the
Start-BitsTransfer
cmdlet to initiate the BITS transfer. The-Source
parameter specifies the download source (URL) stored in the$sourceUrl
variable, and the-Destination
parameter specifies the destination path stored in the$destinationPath
variable.
When Packer runs this provisioner, it will execute the PowerShell script and initiate the BITS transfer to download the file specified by the URL to the specified destination path.
Make sure to adjust the file URL and destination path according to your requirements.
Please note that BITS requires an internet connection, and the download speed may vary depending on the network conditions.
