I am trying to get the Ceph Multisite Clous Sync module working with Amazon S3. The docs are not clear on how the sync module is actually configured. I just want a POC of the most simple config. Can anyone share the config and radosgw-admin commands that were invoked to create a simple sync setup. The closest docs that I have seen are https://croit.io/blog/setting-up-ceph-cloud-sync-module and to be honest they do not make a lot of sense.
I presume (from your last email) that you are familiar with setting up
multisite between zones in a single zonegroup [1] . Cloud sync zone is
similar to creating any other zone [2] but with additional option
'--tier-type=cloud' specified. Below are the minimal steps you may need
to get started with it -
1) To create cloud sync zone-
# radosgw-admin zone create --tier-type=cloud --rgw-zone=<zone-name>
--rgw-zonegroup=<zonegroup-name> --rgw-realm=<realm>
--access-key=<system-user-access-key> --secret=<system-user-secret>
--endpoints=http://{fqdn}:80
eg., radosgw-admin zone create --rgw-zone=cloud-zone
--rgw-zonegroup=default --rgw-realm=realm_default --tier-type=cloud
--access-key=<system-user-access-key> --secret=<system-user-secret>
--endpoints=http://localhost:8002
2) Update cloud zone with the remote endpoint connection details -
# radosgw-admin zone modify --rgw-zone=<zone-name>
--rgw-zonegroup=<zonegroup-name> --rgw-realm=<realm> \
--tier-config=connection.access_key=<remote-endpoint-access-key>,connection.secret=<remote-endpoint-secret>,connection.endpoint=<http://remote-fqdn:port>,connection.host_style=path,acls.source_id=<rgw-user>,acls.dest_id=<remote-endpoint-user>,target-path=<remote-target-path>
note: host_style, acls and target-path are optional. If not specified,
the zone will create a default bucket on the cloud endpoint to sync
entries to and maps the same rgw user to remote endpoint.
eg., radosgw-admin zone modify --rgw-zone=cloud-zone
--rgw-zonegroup=default --rgw-realm=realm_default
--tier-config=connection.access_key=L#############R,connection.secret=Y##########t,connection.endpoint=https://10.xx.xx.xx:80,acls.source_id=testid,acls.dest_id=aws-user,target_path=cloud-sync
3) radosgw-admin period update --commit
4) radosgw-admin sync status // to fetch sync status across zones
including cloud sync zone.
Hope this helps!
