Error: Unable to retrieve project list.

• 호라이즌이 프로젝트 목록을 조회할 수 없다는 오류

2 확인

[root@controller ~]# source keystonerc_admin
[root@controller ~(keystone_admin)]# openstack project list
+----------------------------------+----------+
| ID                               | Name     |
+----------------------------------+----------+

→ CLI에서는 프로젝트 목록이 잘 조회됨

[root@controller ~(keystone_admin)]# cat /usr/local/horizon/openstack_dashboard/local/local_settings.py | grep OPENSTACK_API_VERSIONS -A6
#OPENSTACK_API_VERSIONS = {
#    "data-processing": 1.1,
#    "identity": 3,
#    "image": 2,
#    "volume": 2,
#    "compute": 2,
#}

→ horizon 설정에는 API 버전 정보가 주석처리되어 있음

3 조치

• OPENSTACK_API_VERSIONS 블럭 주석해제

[root@controller ~(keystone_admin)]# vi /usr/local/horizon/openstack_dashboard/local/local_settings.py

OPENSTACK_API_VERSIONS = {
    "data-processing": 1.1,
    "identity": 3,
    "image": 2,
    "volume": 2,
    "compute": 2,
}

• 아파치 리로드

[root@controller ~(keystone_admin)]# systemctl reload httpd
[root@controller ~(keystone_admin)]#
