How to force CloudFormation to use specific S3 bucket if it exists or create it otherwise?

How to set condition in CloudFormation template that it should use a certain S3 bucket if it exists (bucket will have DeletionPolicy: Retain) or should create it if it doesn't exist.

Importing resources won't work because bucket won't be there during the first stack creation.

There is no such functionality in plain CloudFormation. The only choice is to use custom resource.

This is a special type of resource which you have to develop yourself. This is mostly done by means of Lambda Function. So your template would use lambda function in the form of a custom resource to create/check if a given bucket exist or not.
