Configure a Private S3 Bucket

AWS Side:

• Set your S3 bucket to private (block all public access)
• Create IAM user credentials with S3 read permissions
• Optionally, create a bucket policy to restrict access

Reference:

• AWS S3 Security Best Practices
• AWS IAM for S3 Access

Dagster/Teradata Side:

• Change public_bucket=False in the code ("Step 2: Implement AWS S3 to Teradata Transfer")
• Provide AWS credentials (access key, secret key) via environment variables
• Create a Teradata AUTHORIZATION object (see instructions below)
