Question

A company runs a CodePipeline in us-east-1 that builds a container image and deploys it to an Amazon ECS cluster in both us-east-1 and eu-west-1. The team adds a deploy action targeting the eu-west-1 ECS cluster, but when they save the pipeline, CodePipeline returns an error stating that no artifact store exists for the eu-west-1 region. What is the correct way to enable this cross-region deployment?

Accepted Answer

Configure an artifact store (an S3 bucket) in eu-west-1 and associate it with the pipeline for that region so CodePipeline can replicate artifacts before running the cross-region action.

Answer

Enable S3 Cross-Region Replication on the pipeline's us-east-1 artifact bucket and point the eu-west-1 deploy action at the replicated bucket manually.

Answer

Create a second, independent CodePipeline in eu-west-1 and trigger it from the first pipeline using an SNS notification on stage completion.

Answer

Change the pipeline to use a KMS-encrypted artifact store, which automatically makes artifacts available in all regions where deploy actions exist.
