How to make codepipeline in RegionA to use codecommit repo which is in RegionB

Question

I have a requirement where i need to use the existing codecommit repos in RegionB for the codepipelines in RegionA. I have read that codepipeline supports cross-region actions but when i try to do it , I am not able to find region in source stage of codepipeline.
Another way is to do this through replication of codecommit repos into RegionA with a pipeline.
But I am trying to avoid that. Is there any other way to achieve this?

Answer

According to AWS documentation:

> You cannot create cross-Region actions for the following action types: Source actions, Third-party actions, Custom actions

You can find more details regarding cross-region behaviour of AWS Codepipeline here in meantime: https://docs.aws.amazon.com/codepipeline/latest/userguide/actions-create-cross-region.html

Regarding workarounds: there would be two direct ways:
- Repo cross-region replication
- You can hook whatever you desire via AWS EventBridge as there is plenty of triggers being sent to EventBridge: https://docs.aws.amazon.com/codecommit/latest/userguide/monitoring-events.html
