Here is a 150 word summary of the blog post:

The blog post discusses how to securely configure AWS credentials in CI/CD pipelines. Traditionally, long-term AWS keys have been used which poses security risks if exposed. The recommended approach is using short-term credentials from AWS Security Token Service (STS) via an AWS IAM OpenID Connect provider. The post walks through setting up an OpenID Connect provider in AWS IAM, defining an IAM policy to allow assuming roles, and configuring GitHub Actions to obtain temporary AWS credentials using the awsactions/configure-aws-credentials GitHub Action. By adopting short-term credentials in CI pipelines, you can enhance security by reducing the lifespan of credentials thereby minimizing the window for potential unauthorized access. The post provides Terraform and YAML code snippets to demonstrate implementation. Overall, the core message is to avoid using long-term AWS keys in CI pipelines and instead leverage short-term credentials with limited access scoped to only necessary resources.
