Deploy to AWS via GitHub Actions using OIDC — no long-lived access keys needed

A technical guide published on DEV Community outlines how engineering teams can build a secure, reproducible AWS deployment pipeline using GitHub Actions without storing long-lived AWS access keys in their repositories. The approach relies on OpenID Connect (OIDC), which allows GitHub Actions to obtain short-lived AWS credentials by assuming a scoped IAM role, eliminating the risk of key leakage or rotation failures. The setup targets containerized applications on Amazon ECS and introduces two separate IAM roles — one for building and pushing Docker images, another for deploying to production — each restricted to specific repositories and branches. The guide also emphasizes defining explicit pre- and post-deployment checks, including blocking controls such as tests, linting, and manual approvals. A key principle stressed throughout is that a rollback procedure must be written down and successfully tested by a team member before it is ever needed in a real incident.
