Codepipeline: Only one of artifact bucket and cross region replication buckets can be specified!

[makr11]

Describe the feature

I couldn't find an explanation of this constraint. It would be extremely beneficial to be able to specify cross region replication bucket to be reused for all project pipelines which create cross region resources.

Use Case

Large amount of pipelines created with CDK creates a near limit amount of S3 Buckets, I would like to specify cross region replication bucket alongside artifact bucket.

Proposed Solution

Hi pahud,

This is the full error log:

jsii.errors.JavaScriptError:

The above exception was the direct cause of the following exception:

Hey, any update around this issue?

Hi @makr11

For cross-region and/or cross-account issues with codepipeline, we have a p1 issue for tracking at #24051 and please report to that issue instead.

If you are looking for a working sample for your reference, please check this out.

I am getting the same error. I would like to use a single bucket for artifacts and replication buckets because otherwise we reach the 100 bucket limit quickly. If a single bucket cannot be used, at least 2 buckets, one for artifacts and one for replication would also be good.

const artifactBucket = Bucket.fromBucketName(this, `ID`, 'existing_bucketname');

const pipeline = new CodePipeline(this, `ID`, {
    artifactBucket: artifactBucket,
    crossRegionReplicationBuckets: {
        'us-east-1': artifactBucket,
    },
   ...
};

Results in: Error: Only one of artifactBucket and crossRegionReplicationBuckets can be specified! when trying to do cdk synth.
