Summary: [Website v2] [Docs] [Core Concepts] Ozone Volume/Bucket
name allowed characters
Key: HDDS-14404
URL: https://issues.apache.org/jira/browse/HDDS-14404
Project: Apache Ozone
Issue Type: Sub-task
Components: documentation
Reporter: Wei-Chiu Chuang
Add a note block on volume/bucket name:
To maintain S3 compatibility, Ozone volume and bucket name follows S3 naming
convention.
This means volume/bucket names in Ozone:
* Allowed Characters and Length
* Allowed characters: Lowercase letters (a-z), numbers (0-9), dots (.), and
hyphens ( - ).
* Length: Must be between 3 and 63 characters long.
* Start and End: Must begin and end with a letter or a number.
Prohibitions
* Cannot contain uppercase letters or underscores (_).
* Cannot be formatted as an IP address (e.g., 192.168.5.4).
* Cannot have consecutive periods (e.g., my..bucket) or have dashes adjacent to
*periods (e.g., my-.bucket).
* Cannot end with a dash.
This can cause confusions when migrating HDFS workloads to Ozone, since HDFS
path names are POSIX-compliant.
To relax the compliance check, configure the property
ozone.om.namespace.s3.strict to false in the ozone-site.xml of Ozone Manager.
