---------------------------------
Summary: Review and support IPv6-capable bind-address defaults
Key: HDDS-15778
URL: https://issues.apache.org/jira/browse/HDDS-15778
Project: Apache Ozone
Issue Type: Task
Reporter: Siyao Meng
All service bind defaults are the IPv4 wildcard 0.0.0.0, which does not bind on
IPv6-only hosts:
- HddsConfigKeys.HDDS_DATANODE_CLIENT_BIND_HOST_DEFAULT
(HddsConfigKeys.java:373)
- ScmConfigKeys client/block-client/datanode/scm bind defaults
(ScmConfigKeys.java:179,187,202,218)
- OMConfigKeys.OZONE_OM_BIND_HOST_DEFAULT (OMConfigKeys.java:76)
- S3GatewayConfigKeys.OZONE_S3G_HTTP_BIND_HOST_DEFAULT
(S3GatewayConfigKeys.java:52)
- ozone-default.xml RPC address defaults such as 0.0.0.0:9862.
Proposed: decide the dual-stack vs IPv6-only binding behavior (for example
supporting :: wildcard), document operator guidance, and update
ozone-default.xml accordingly.
