CloudFormation scenarios to Create S3 Bucket with 'BucketAlreadyExists' scenarios in Multi-Region Stack
I'm migrating some code and I'm trying to debug I'm trying to implement I'm building a feature where I tried several approaches but none seem to work... I'm stuck on something that should probably be simple. I'm trying to deploy a CloudFormation stack that includes the creation of an S3 bucket for storing logs. However, during the stack creation process, I encounter the behavior: `BucketAlreadyExists: The requested bucket name is not available`. This happens even though I’m specifying a globally unique bucket name. My configuration looks like this: ```yaml Resources: LogBucket: Type: 'AWS::S3::Bucket' Properties: BucketName: my-unique-log-bucket-name-2023 VersioningConfiguration: Status: Enabled LifecycleConfiguration: Rules: - Id: LogLifeCycle Status: Enabled ExpirationInDays: 365 ``` I've tried deploying this in both the `us-east-1` and `eu-west-1` regions, but the behavior continues. I've also verified that no other accounts have created a bucket with the same name by using the AWS CLI with the command `aws s3api head-bucket --bucket my-unique-log-bucket-name-2023`, which returns an behavior indicating the bucket does not exist. Additionally, I’ve checked the IAM permissions and confirmed that my role has sufficient rights to create S3 buckets. I suspect this could be related to the way CloudFormation manages stack resources across different regions or some caching scenario, but I’m not sure. What are the best practices for naming S3 buckets in CloudFormation to avoid these kinds of issues, especially when deploying stacks in multiple regions? Any insights or suggestions would be greatly appreciated! Am I missing something obvious? What's the best practice here? For reference, this is a production application. Thanks, I really appreciate it! Thanks for taking the time to read this! I appreciate any insights!
