About PSLinodeDnsClient Module

The PSLinodeDnsClient module is a PowerShell module that provides a set of functions to interact with the Linode API for managing domains and domain records. It allows users to perform operations such as retrieving a list of domains and records, fetching specific domains or records, and updating domain records. This module makes it easy for you to manage your Linode DNS settings programmatically using PowerShell.

Prerequisites

1. This module was tested with Powershell 7.3, but should also work with 5.1. It was tested on Windows and Ubuntu Linux, you can find the install instructions below.
   • Powershell Core for Windows
   • Powershell Core for Linux
2. This module uses PSFramework so make sure you install that before hand.
   • Make sure your pwsh or terminal is running with elevated privileges and run the below command to install

     Install-Module PSFramework

   • You can confirm the module installed by running the following command

     Get-Module -ListAvailable PSFramework

3. Make sure to edit the config.json file and change the DomainId and Authentication header with your API key. The config file is loaded when the module is imported.
   • After putting your API key in the config, you can use Get-DomainList to fetch a list of your domains and get the Id of the domain you want to run the script against.

Example uses

Take a look at the Example script for a working script to automatically update your Linode DNS's.
