Hello.

I was able to make swift run with ceph by restart osd daemon. . 

Thank you @Danny Webb and @Eugen Block. I follow your advices and do it.

Summary:

recreate swift endpoint which need point ceph gw

create openstack user and account for ceph gw. project is service

and set parameters like 

https://docs.ceph.com/en/latest/radosgw/keystone/

with new cephadm we need use "ceph config set" and restart osd daemon.

@Jeremy Stanley I think too. Is there any idea use ceph instead of swift completely? I feel not much people use swift.

Hi,

not so long ago I wrote down what was necessary in my lab environment 
to configure a cephadm based cluster with keystone authentication for 
S3 (swift) clients. In Openstack you need swift endpoints which point 
to the rados gateway(s) in your external ceph cluster. So you don't 
really set up swift but only create the endpoints for your clients. I 
can't comment what exactly needs to be done with kolla but you should 
get the general idea, I hope.

Regards,
Eugen
