EC2 InvalidAMIID.NotFound error when trying to launch an EC2 instance.

The specified AMI ID does not exist or is incorrect.

Understanding Amazon EC2 and Its Purpose

Amazon Elastic Compute Cloud (EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. EC2 allows you to launch virtual servers, known as instances, which can be used to run applications, host websites, or perform other computing tasks.

Identifying the Symptom: InvalidAMIID.NotFound

When attempting to launch an EC2 instance, you may encounter the error code InvalidAMIID.NotFound. This error indicates that the Amazon Machine Image (AMI) ID you specified does not exist or is incorrect. As a result, the instance launch process cannot proceed.

Explaining the Issue: Invalid AMI ID

The InvalidAMIID.NotFound error occurs when the AMI ID provided does not match any existing AMI in the specified region. This can happen if the AMI ID is mistyped, the AMI has been deregistered, or if the AMI is located in a different AWS region.

Common Causes of the Error

  • Typographical errors in the AMI ID.
  • The AMI has been deleted or deregistered.
  • The AMI ID is from a different AWS region.

Steps to Fix the InvalidAMIID.NotFound Error

To resolve this issue, follow these steps:

Step 1: Verify the AMI ID

Ensure that the AMI ID you are using is correct. You can do this by checking the AMI ID in the AWS Management Console:

  • Navigate to the EC2 Dashboard.
  • Click on AMIs in the left-hand menu.
  • Search for the AMI ID to confirm its existence.

Step 2: Check the AMI's Region

Ensure that the AMI ID is available in the region where you are trying to launch the instance. AMI IDs are region-specific, and using an AMI ID from a different region will result in this error.

  • Switch to the correct region using the region selector in the top-right corner of the AWS Management Console.

Step 3: Confirm AMI Availability

If the AMI has been deregistered, it will not be available for use. You may need to select a different AMI or contact the AMI owner for more information.
