[StarCluster] Saving a custom AMI

[Justin Riley]

Hi Chris,

I apologize for the delay. You're right that capital letters are an issue. StarCluster attempts to validate the bucket name based on the rules defined here:

http://docs.amazonwebservices.com/AmazonS3/latest/dev/index.html?BucketRestrictions.html

This states that bucket names should consist of only "lowercase letters, numbers, periods (.), underscores (_), and dashes (-)". That being said Amazon also recommends for DNS purposes that the name does not contain underscores. However, looking at the code I believe StarCluster will still allow you to create buckets with underscores in the name assuming it's not the first character. Have you tried using the underscores with only lower-case letters?
