2.5. Bucket and Key Naming Policies¶
It is recommended to use bucket names that comply with DNS naming conventions:
- can be from 3 to 63 characters long,
- must start and end with a lowercase letter or number,
- can contain lowercase letters, numbers, periods (.), hyphens (-), and underscores (_),
- can be a series of valid name parts (described previously) separated by periods.
An object key can be a string of any UTF-8 encoded characters up to 1024 bytes long.
