Bucket and Key Naming Policies
It is recommended to use bucket names that comply with DNS naming conventions:
- 3 to 63 characters long.
- Start and end with a lowercase letter or number.
- Contain lowercase letters, numbers, periods (.), hyphens (-), and underscores (_).
- Can be a series of valid name parts (described previously) separated by periods.
note
- Bucket names must be unique. Otherwise you may get an error.
An object key can be a string of any UTF-8 encoded characters up to 1024 bytes long.
