Body

I’m setting up GitHub Actions workflows that deploy to multiple environments (e.g., dev, staging, production), and I’m wondering what the best practices are for managing secrets securely across them.

Questions:

Should secrets be stored at the repository or environment level?

How do you prevent accidental leaks between environments?

Any tips for rotating secrets or using external secret managers?

Appreciate any insights or examples from your setup!

Use environment-level secrets in GitHub Actions for better separation between dev, staging, and production. This way, each workflow can access only the secrets it needs based on the deployment environment.

For added security:

Enable required reviewers for production environments.

Use external secret managers like AWS Secrets Manager or HashiCorp Vault for rotation and centralized control.

Avoid hardcoding secrets—always reference them via ${{ secrets.SECRET_NAME }}.
