What is awscurl?

awscurl is a command-line tool that extends the functionality of curl by automatically signing HTTP requests with AWS Signature Version 4 (SigV4). This signing is necessary for making authenticated requests to AWS services, allowing users to interact with AWS APIs directly from the command line in a secure manner.

Why is it useful?

• Security: It handles the complex task of request signing, which is essential for security when interacting with AWS services that require authentication.
• Convenience: It simplifies the process of making authenticated requests to AWS services, much like curl does for general HTTP requests, but with the added layer of AWS authentication.
• Versatility: Supports various AWS services like S3, EC2, API Gateway, etc., making it versatile for developers and system administrators who need to test or interact with AWS resources programmatically or manually.
• Compatibility: It can be used in environments where direct AWS SDK usage might be cumbersome or not feasible, like in CI/CD pipelines or quick testing scenarios.

Where is the documentation?

Documentation for awscurl can be found in several places:

• GitHub:

1. For one of the implementations, you can refer to the GitHub repository by okigan. This repo includes usage instructions, installation guides, and examples of how to use awscurl with different AWS services.

2. Another implementation by legal90 provides detailed command-line options and usage examples on their GitHub page.

• AWS Documentation: Specific uses of awscurl for AWS services like Amazon Neptune or Amazon Managed Service for Prometheus can be found in AWS's official documentation, where they provide examples and explanations on how to connect or query these services using awscurl. See examples:

1. Connecting to Amazon Neptune databases using IAM authentication from the command line
2. Use awscurl to query with Prometheus-compatible APIs

• PyPI: If you're using the Python version, awscurl on PyPI has basic installation instructions and usage examples (awscurl - PyPI). See repo at https://pypi.org/project/awscurl/

These resources should provide comprehensive guidance on how to use awscurl, its features, and how to integrate it into your AWS workflow.
