Version 1.0 Upgrade Guide

This document outlines a way to upgrade this module from v0.x to v1.0 or later. The following guidance only applies if var.use_external_audit_log_bucket is set to false, which is a default behavior.

Following the changes introduced in AWS provider v4.0, several configurations for S3 buckets were extracted from aws_s3_bucket resource to newly added resources. It is recommended to import these resources before running terraform apply to prevent data loss.

See the upgrade guide for AWS provider for more detail.

Audit log bucket migrations

Following configurations from module.audit_log_bucket[0].aws_s3_bucket.content were extracted to separated resources.

  • module.audit_log_bucket[0].aws_s3_bucket_acl.content
  • module.audit_log_bucket[0].aws_s3_bucket_lifecycle_configuration.content
  • module.audit_log_bucket[0].aws_s3_bucket_logging.content
  • module.audit_log_bucket[0].aws_s3_bucket_server_side_encryption_configuration.content
  • module.audit_log_bucket[0].aws_s3_bucket_versioning.content

To import the current configuration into these resources, use terraform import command as follows.

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_acl.content" "$AUDIT_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_lifecycle_configuration.content" "$AUDIT_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_logging.content" "$AUDIT_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_server_side_encryption_configuration.content" "$AUDIT_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_versioning.content" "$AUDIT_LOG_BUCKET"

Notes

  • $MODULE_PATH should be replaced the actual path of this module in your project, e.g. module.secure_baseline.
  • $AUDIT_LOG_BUCKET should be replaced with the state bucket name. The actual value in your state file as module.audit_log_bucket.aws_s3_bucket[0].content.id.

Access logging bucket migrations

Following configurations from module.audit_log_bucket[0].aws_s3_bucket.access_log were extracted to separated resources.

  • module.audit_log_bucket[0].aws_s3_bucket.access_log
  • module.audit_log_bucket[0].aws_s3_bucket_acl.access_log
  • module.audit_log_bucket[0].aws_s3_bucket_lifecycle_configuration.access_log
  • module.audit_log_bucket[0].aws_s3_bucket_server_side_encryption_configuration.access_log

These resources can be imported by terraform import command as well.

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket.access_log" "$ACCESS_LOG_BUCKET"
$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_acl.access_log" "$ACCESS_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_lifecycle_configuration.access_log" "$ACCESS_LOG_BUCKET"

$ terraform import "$MODULE_PATH.module.audit_log_bucket[0].aws_s3_bucket_server_side_encryption_configuration.access_log" "$ACCESS_LOG_BUCKET"

Notes

  • $MODULE_PATH should be replaced the actual path of this module in your project, e.g. module.secure_baseline.
  • $ACCESS_LOG_BUCKET should be replaced with the state bucket name. The actual value in your state file as module.audit_log_bucket[0].aws_s3_bucket.access_log.id.
