S3 Replication Improvements @alexjurkiewicz (#93)

Terraform plan impact

In order to support multiple S3 Bucket replication destinations, we must use the filter in the replication rule, even if there is nothing to filter. The filter, even if empty, conflicts with the prefix attribute of the rule (a v1 feature replaced in v2 with the filter). So we moved all prefix settings into the filter. Therefore, you may see Terraform make a change like this:

- rules {
  - id       = "replication-test"
  - prefix   = "/main"
  - priority = 0
  - status   = "Enabled"

  - destination {
    - bucket        = "arn:aws:s3:::replication-target"
    - storage_class = "STANDARD"
  }

  - filter {}
- }

+ rules {
    + id       = "replication-test"
    + priority = 0
    + status   = "Enabled"

    + destination {
        + bucket        = "arn:aws:s3:::replication-target"
        + storage_class = "STANDARD"
      }

    + filter {
        + prefix = "/main"
        + tags   = {}
    + }
+ }

This change is harmless and can be applied without impact.

Deprecation

To provide consistency in naming, the replication_rules input has been deprecated in favor of s3_replication_rules. Existing code will continue to work, but new users should use s3_replication_rules and current users of replication_rules should update their code to use s3_replication_rules at their convenience.

what

@alexjurkiewicz

• Add support for multi-bucket S3 replication
• Add support for easily adding cross-account replication destination bucket policy statements

@korenyoni

• Add test for S3 bucket replication configuration to provide better code coverage

@Nuru

• Convert v1 prefix to v2 filter to support multiple replication destinations
• Rename replication_rules to s3_replication_rules for consistency
• Move testing to us-east-2 region because that is where Cloud Posse prefers to do testing

why

• Module currently does not support multi-bucket S3 replication
• Adding cross-account replication destination bucket policy statements is currently a manual task with no site-specific uniqueness
