The landing page cannot load the list of domains

[Apeng]

openstack version: Train
Hi, after deploying as docker, I open the login page, the region is displayed correctly but the domain list is empty, which prevents me from selecting the domain to complete the login. I have checked the region and domain list via command line tool.
Please see the attachment for the configuration file and docker logs.
Thanks!

[root@ctrl02 ~]# openstack region list
+--------+---------------+-------------+
| Region | Parent Region | Description |
+--------+---------------+-------------+
| YHDC01 | None | |

[root@ctrl02 ~]# openstack domain list

openstack:
  base_domains:
  - Default

I see you set the base_domains as Default. The base_domains will be ignored from the domains list api.I should set this with 'Domain_heat'

[Apeng (user0x5a0x50)]

Thanks for your answer, I tried to remove the 'default' item and re-executed the deployment process, but there is still no list of available domains.

Please supply the logs of skyline that is under /var/log/skyline.

We have found the problem, because the service name we set in bootstrap keystone of openstack is not the default value "keystone", we changed it to "srvc_keystone". In the skyline code, part of the logic of getting the token, the service name "keystone" matches the authentication service from the endpoint list, and the operation of changing the service name leads to not getting the endpoint of the authentication service.
Thank you again for your help and for skyline's open source spirit and contributions.

[Boxiang Zhu (bxzhu-5355)]

Great, thanks for your reply the reason. So the service name is not "keystone" for your openstack cluster. But the codes for skyline-apiserver is hardcode as "keystone". Maybe we can set this as config for skyline.

Thanks

Is this resolved? Or could anyone of you help me understand where should I change to resolve the issue at least temporarily?

[Shuai Qian (iauhsnaiq)]

Hello Debasis,

if you also cant get domain list in the landing page, check your configuration file of skyline, and make sure that your domains are not in the item base_domains.

if your skyline configuration is correct, check as following:
- make sure your keystone service works, and you can get domain list through calling keystone api manually.
- and your identity service name is keystone, in case of the same issue above.

[Debasis (debamondal)]

Hi Shuai,

When I execute openstack service list, I get "keystone" as the identity service and in the skyline.yaml, I've the following...

openstack:
  base_domains:
  - heat_user_domain
  default_region: RegionOne
  extension_mapping:

My skyline frontend domain and region both are empty and client getting 401 error code(this is unexpected because on the login page you cannot expect user to have authentication key)

[Shuai Qian (iauhsnaiq)]

regions and domains in login page would be got by system_user configurated in skyline.yml

and 401, it sounds like you have wrong system_user_password or other related configurations in your skyline.yaml

so please check your configurations in skyline.yml, especially those startswith system_
