AWS CDK Pipelines 创建多个工件桶

Question

I'm having some trouble with CDK Pipeline/ CodePipeline in AWS. When I run the pipeline (git commit) the Assets section always runs even if I don't change the files that it is building and every pipeline execution creates an S3 bucket with pipeline assets so we have loads of s3 buckets. This behaviour while odd does seem to work but it takes a long time to run and doesn't seem right. Is this to be expected and if not what may be the issue?

Update We sometimes see the below error msg in the build logs which may be related but it doesn't cause failure:

Failed to store notices in the cache: Error: ENOENT: no such file or directory, open '/root/.cdk/cache/notices.json'

Answer 1

If you create an S3 bucket and then reference that bucket in your Codepipeline, the output will always be in that S3 bucket, and the artifacts will be sub directories of that specific S3 bucket. That way you will get new build assets, but they will be placed inside of the same bucket, and you only have one S3 bucket.
