Fixed In Version: ceph-17.2.3-24.el9cp
Doc Type: Bug Fix
Doc Text:
.The Ceph Object Gateway daemons now bind to loopback addresses correctly Previously, `cephadm` excluded loopback interfaces when looking for a valid IP address on a host to bind the Ceph Object Gateway daemon, thereby the daemons would not bind to the loopback addresses. With this fix, the Ceph Object Gateway daemons can be bound to loopback addresses by performing an explicit check. If a loopback interface is detected, the `127.0.0.1` address is used for IPv4 and `::1` is used for IPv6 as the loopback address.

Description James Poole 2021-10-28 15:42:10 UTC 
Description of problem:
In RHCS 4 we were able to bind the RADOS gateway to localhost with "endpoint=127.0.0.1:8080" in ceph.conf for example. If we provide network of '127.0.0.0/8' in the server specification yaml the RADOS gateway fails to deploy. 

Version-Release number of selected component (if applicable):
5.0

How reproducible:
Every time, see below

Steps to Reproduce:
1. Create RADOS gateway with the following yaml:
---
service_type: rgw
service_id: ceph.prod
service_name: rgw.ceph.prod
placement:
  count_per_host: 1
  label: rgw_prod
networks:
- 127.0.0.0/8
spec:
  rgw_frontend_port: 8080
  rgw_realm: prod
  rgw_zone: prod
2. ceph orch apply -i rgw-service.yml
3. See rgw.ceph.prod remains 0/1 in `ceph orch ls`

Actual results:
RADOS gateway fails to deploy

Expected results:
RADOS gateway deploys and bound to 127.0.0.1:8080

Comment 2 Ken Dreyer (Red Hat) 2022-07-29 18:51:59 UTC 
Is 127.0.0.0/8 documented anywhere? Did you try 127.0.0.0/32 instead?
Comment 3 Redouane Kachach Elhichou 2022-08-24 10:02:17 UTC 
Thanks for reporting the issue.

Is there any use-case in customer/production for this request?
