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 users to launch and manage server instances in Amazon's data centers and is integrated with AWS services like IAM (Identity and Access Management).
An IAM instance profile is a container for an IAM role that you can use to pass role information to an EC2 instance when the instance starts. This allows the instance to obtain temporary security credentials to access AWS resources.
When working with EC2, you might encounter the error code InvalidIAMInstanceProfileID.NotFound. This error typically occurs when you attempt to launch or modify an EC2 instance with an IAM instance profile that does not exist or is incorrectly specified.
The primary symptom of this issue is the failure to launch or modify an EC2 instance due to the specified IAM instance profile ID being unrecognized by AWS. This can halt your deployment process and prevent your instances from obtaining necessary permissions.
The InvalidIAMInstanceProfileID.NotFound error indicates that the IAM instance profile ID provided does not match any existing profiles in your AWS account. This could be due to a typo, an incorrect ID, or the profile being deleted.
To resolve this issue, follow these steps:
aws iam list-instance-profiles
aws iam get-instance-profile --instance-profile-name <ProfileName>
For more information on managing IAM instance profiles and roles, refer to the following resources:
By following these steps, you should be able to resolve the InvalidIAMInstanceProfileID.NotFound error and successfully launch or modify your EC2 instances with the correct IAM instance profile.
