Overview

The download_file module allows you to download files on Windows

Module Description

The download_file module introduced a small define download_file that will allow you to download a file over http(s) for usage during an installation. This was created because the package resource does not support http as a source for packages. It is only supported on Windows.

Setup

What download_file affects

• Downloads files onto each node

Setup Requirements

• download_file makes use of Powershell so you will need to have at least version 2.0 installed in order to use this module.

Beginning with download_file

To download dotnet 4.0

    download_file { "Download dotnet 4.0" :
      url                   => 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe',
      destination_directory => 'c:\temp'
    }

To download dotnet 4.0 using a proxy

    download_file { "Download dotnet 4.0" :
      url                   => 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe',
      destination_directory => 'c:\temp',
      proxy_address         => 'http://corporateproxy.net:8080'
    }

The proxy will be used as part of the download using PowerShell. This does not set a system wide proxy

Usage

Reference

Defined Types

Public Types

• download_file: Download a give file

Parameters

url

The http(s) destination of the file that you are looking to download

destination_directory

The full path to the directory on the system where the file will be downloaded to

destination_file

The optional name of the file to download onto the system.

user

The optional userid is used when authenticating via Basic Auth with the server. user and password must be specified or this has no effect.

password

The optional password is used when authenticating via Basic Auth with the server. user and password must be specified or this has no effect.

proxy_address

The optional http proxy address to use when downloading the file

proxy_user

The optional http proxy user to use when downloading the file. proxy_address and proxy_password must be specified or this has no effect.

proxy_password

The optional http proxy password to use when downloading the file. proxy_address and proxy_user must be specified or this has no effect. By default this value accepts secure strings. A secure string is (unfortunately) tied to the machine that it is used for. To generate a secure string for a given machine, users should run the following powershell command on that machine (replacing PASSWORD with the desired password):

ConvertFrom-SecureString -securestring $(ConvertTo-SecureString "PASSWORD" -AsPlainText -Force)

It is possible to get this information then clear the command from history, but it's important to note that the -Force argument is there to suppress warnings that the plaintext password is in the history.

If this process sounds unappealing, you can send the password in plaintext (which sits in the download-<filename>.ps1 file on the machine being provisioned) by changing the is_password_secure variable to false.

is_password_secure

The optional switch to change the way that proxyPassword is interpreted from secure string to plaintext. This will send the password in plaintext to the machine being provisioned, which may be a security concern.

cookies

An optional array of cookies to add to the HTTP request for the download.
