How to Execute PowerShell Scripts Remotely on an Amazon EC2 Instance from Your Local Computer

In the era of cloud computing, being able to execute scripts remotely is a crucial skill for any software engineer or data scientist. Amazon Web Services (AWS) EC2 instances are an excellent example of remote resources that can be managed through scripts. This blog post will guide you on how to execute PowerShell scripts remotely on an Amazon EC2 instance from your local computer.

Prerequisites

Before we start, ensure that you have:

• An Amazon EC2 instance up and running, preferably with Windows Server as the operating system.
• AWS CLI installed on your local machine. You can download it from here.
• PowerShell 5.1 or later on your local machine.

Step 1: Enable PowerShell Remoting on EC2 Instance

PowerShell remoting needs to be enabled on your EC2 instance. This can be done through the AWS Management Console. Connect to your instance and run the following command in the PowerShell terminal:

Enable-PSRemoting -Force

Step 2: Set Up Your Local Machine

On your local machine, open PowerShell with administrative privileges and run the following command to ensure that your machine can establish remote connections:

Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*"

Replace * with your EC2 instance’s public IP address if you want to restrict remote connections to that EC2 instance only.

Step 3: Establish Remote Session

Now you’re ready to establish a remote session. Replace <username> with your EC2 instance username and <public-ip> with your EC2 instance’s public IP address:

$session = New-PSSession -ComputerName <public-ip> -Credential <username>

This command will prompt you to enter your password. Once entered correctly, it will establish a remote session and save it in the $session variable.

Step 4: Execute Your PowerShell Script

With the session established, you can invoke commands or scripts on your EC2 instance. Let’s say the script you want to run is located on your local machine at C:\scripts\myscript.ps1. To execute it remotely, run:

Invoke-Command -Session $session -FilePath C:\scripts\myscript.ps1

The above command will execute the script on your EC2 instance.

Step 5: Close the Session

After executing your commands or scripts, it’s a good practice to close the session. This can be done with:

Remove-PSSession -Session $session

Conclusion

In this post, we’ve seen how to execute PowerShell scripts remotely on an Amazon EC2 instance from your local computer. This method is valuable when automating tasks on your EC2 instances. It’s essential to remember that PowerShell remoting should be managed securely to avoid potential security risks. Always restrict your trusted hosts and use secure passwords for your EC2 instances.

Remember, with great power(shell) comes great responsibility!
