Question 1

How do I set up Cross-Region Replication with terraform-aws-s3-bucket?

Accepted Answer

Use the replication_configuration input variable with a map defining rules, roles, and destinations. The module handles IAM role creation and policy attachments, as shown in the S3 replication example in the README's examples section.

Question 2

What's the difference between this module and using the native AWS S3 resource in Terraform?

Accepted Answer

This module abstracts complex configurations, provides sensible defaults, and includes pre-built policies for log delivery and security, reducing boilerplate code and potential errors. In contrast, the native resource requires manual setup for each feature, increasing development time.

Question 3

How can I attach a custom bucket policy with placeholders in this module?

Accepted Answer

Define the policy JSON in the policy argument using placeholders like _S3_BUCKET_ID_ or _AWS_ACCOUNT_ID_. The module automatically substitutes these with actual values during deployment, as explained in the custom policy usage example.

Question 4

Is terraform-aws-s3-bucket compatible with Terragrunt?

Accepted Answer

Yes, it supports Terragrunt by allowing jsonencode()-string for any type variables to work around a known Terragrunt bug, as documented in the README under the Terragrunt section with an example terragrunt.hcl snippet.

Question 5

How to enable static website hosting using this module?

Accepted Answer

Set the website input variable with a map containing index_document, error_document, or redirect rules. The module manages the aws_s3_bucket_website_configuration resource, as demonstrated in the examples for complete S3 bucket configurations.

Question 6

Can I use this module for S3 Directory Buckets, and what are the requirements?

Accepted Answer

Yes, by setting is_directory_bucket = true and configuring related parameters like type, location_type, and data_redundancy. The module uses the aws_s3_directory_bucket resource, with examples provided in the S3 Directory Bucket example directory.

Question 7

How do I manage bucket lifecycle rules for cost optimization?

Accepted Answer

Use the lifecycle_rule input variable with a list of maps specifying transitions, expirations, and filters. The module creates the aws_s3_bucket_lifecycle_configuration resource, detailed in the examples and input variables documentation.
