Naming a bucket

To name a bucket, we have to follow some rules imposed by the fact; as we anticipated, all the buckets reside in the only Google Storage namespace. Bucket names must comply with the following rules:

• They must be 3 to 63 characters long
• They must start and end with a number or a letter
• They must contain only lowercase letters, numbers, dots, and dashes
• They cannot be represented as an IP address in dotted decimal notation
• They cannot start with the prefix GOOG
• They cannot contain two adjacent points or a dash before or after a point

Finally, it should be noted that once you have created the name of a bucket, you cannot change it. To change it, you should create a new bucket with the desired name and move the contents from the old bucket to the new bucket.
