Terraform is an open-source infrastructure as code (IaC) tool created by HashiCorp. It allows developers to define and provision data center infrastructure using a high-level configuration language. Terraform supports multiple cloud providers, including AWS, GCP, and Azure, enabling users to manage infrastructure across different platforms consistently.
When using Terraform with AWS, you might encounter the error: Error: No valid credential sources found for AWS Provider
. This error typically occurs during the execution of Terraform commands such as terraform plan
or terraform apply
, indicating that Terraform cannot authenticate with AWS due to missing or invalid credentials.
The error message "No valid credential sources found for AWS Provider" signifies that Terraform is unable to locate valid AWS credentials required to make API requests. AWS credentials are essential for Terraform to interact with AWS services and provision resources. This issue arises when Terraform is not configured to access AWS credentials through any of the supported methods.
To resolve this error, you need to ensure that Terraform can access valid AWS credentials. Here are the steps to fix the issue:
Set the AWS credentials using environment variables. This is a straightforward method and involves setting the following variables:
export AWS_ACCESS_KEY_ID=your_access_key_id
export AWS_SECRET_ACCESS_KEY=your_secret_access_key
Ensure these variables are set in your shell session before running Terraform commands.
Another method is to use the AWS shared credentials file, typically located at ~/.aws/credentials
. Ensure this file contains the necessary credentials:
[default]
aws_access_key_id=your_access_key_id
aws_secret_access_key=your_secret_access_key
For more information, refer to the AWS CLI Configuration Files documentation.
If you are running Terraform on an AWS EC2 instance, you can use IAM roles to provide credentials. Ensure the instance has an IAM role with the necessary permissions attached. Terraform will automatically use the instance profile credentials.
