Terraform Module for managing s3 bucket cross-account cross-region replication. you may not use this file except in compliance with the License. There are many possible scenarios where setting up cross-region replication will prove helpful. Terraform: Cross Account S3 Bucket Access Control Blag For the Cross Region Replication (CRR) to work, we need to do the following: Enable Versioning for both buckets; At Source: Create an IAM role to handle the replication; Setup the Replication for the source bucket; At Destination: Accept the replication; If both buckets have the encryption enabled, things will go smoothly. I have started with just provider declaration and one simple resource to create a bucket as shown below-. terraform { backend "s3" { bucket = "mybucket" key = "path/to/my/key" region = "us-east-1" } } Copy. It serves as one central place for users, S3 buckets, and other shared resources. This software is released under the MIT License (see LICENSE). I've also done some batch runs to cover pre-existing objects since replication only works with newly added data. This article discusses a method to configure replication for S3 objects from a bucket in one AWS account to a bucket in another AWS account, using server-side encryption using Key Management Service (KMS) and provides policy/terraform snippets.

Alternatively, you can set up rules to replicate objects between buckets in the same AWS Region by using Amazon S3 Same-Region Replication (SRR). Copyright 2018 Leap Beyond Emerging Technologies B.V. A tag already exists with the provided branch name. Required source_bucket_name - Name for the source bucket (which will be created by this module) source_region - Region for source bucket dest_bucket_name - Name for the destination bucket (optionally created by this module) If not creating the destination bucket with this module: https://docs.aws.amazon.com/AmazonS3/latest/dev/crr.html, Ensure that versioning is enabled for the destination bucket (Cross-region replication requires versioning be enabled: see Requirements at, Also follow the manual step above to enable setting owner on replicated objects. The tokens issued when a principal assumes an IAM role are temporary. (How to use trust policies with IAM roles): In the following code, the user ("random") in trusted (dev) account assumes a role that has a permission for listing S3 bucket in trusting (prod) account. This command will tell you how many AWS resources are going to be added, changed or destroyed. If it doesn't show up in the destination bucket quickly, you can check file in the console. S3 service mustbe allowed permissionsto replicate objects from the source bucket to the destination bucket on your behalf. Both source and destination buckets must have versioning enabled. In the second account (lets call it prod), were creating a role with a policy to allow that role to be assumed from the utils account. Are you sure you want to create this branch? 1. 3. Create IAM policy allowing KMS keys to encrypt and decrypt, 3. AWS S3 Documentation mentions that the CMK owner must grant the source bucket owner permission to use the CMK.

Work fast with our official CLI. A user can request access to a role, which will grant that user that roles temporary privileges. For information on what is . This trust policy reduces the risks associated with privilege escalation. Requirements An existing S3 Bucket with versioning enabled Access to a different AWS account and/or region Architecture Source Bucket can be encrypted Versioning on Source Bucket will always be enabled (requirement for replication) Target Bucket will always be encrypted To run this example you need to execute: $ terraform init $ terraform plan $ terraform apply On the first step of the edit wizard, choose the correct KMS key from the pick list titled "Choose one or more keys for decrypting source objects"; Select the existing configuration on each of the next steps of the wizard. Note that for the access credentials we recommend using a partial configuration. In the walkthrough above,I have shownhow to configure replication to copy objects across AWS accounts. If you want to use the newly created user, add a password to it and login as that user into the utils account. You signed in with another tab or window. The way roles work is by using a web service called AWS Security Token Service (STS) to request temporary credentials for IAM, which are then used to identify you as that role.
