Summary
Replaces static AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY GitHub secrets
with OIDC role assumption across all workflows. This is more secure
as it eliminates long-lived AWS credentials stored as GitHub secrets.
Changes
main.yml — switched to OIDC auth, bumped configure-aws-credentials v1 → v4 (required for OIDC), added permissions: id-token: write block (required for GitHub to issue OIDC token)
Testing
✅ CI passed on this branch
✅ AWS credentials step passes with OIDC role assumption confirmed
After this is merged
The following repo secrets can be deleted by an admin if not used in other areas of the pipeline:
AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_OIDC_ROLE_ARN must remain.
