freezer-scheduler auth_url error

[Alessio Fioravanti]

Hello,
I'm experiencing a problem scheduling jobs with freezer.
When I create a job and schedule it from Horizon, freezer-scheduler always fails. The error shown in freezer-scheduler.log (from fluentd container) is:

2019-07-17 07:48:23.294 6 WARNING freezer.scheduler.scheduler_job [-] Job 1754ea4157b94acb916f8b9911886792 failed backup action, retrying in 60 seconds
2019-07-17 07:49:24.342 6 ERROR freezer.scheduler.scheduler_job [-] Freezer client error: Critical Error: auth_url required to authenticate. Make sure to export OS_AUTH_URL=http://keystone_url:5000/v3

Openstack and freezer have been installed with Kolla (I added enable_freezer: "yes" in all.yml).

Here some details:

Environment

kolla version: 8.0.1rc1
openstack release: stein
base container: centos
host os: ubuntu 18.04
environment: 1 controller on a dedicated host + 1 compute on a dedicated host

Thanks,
Alessio

Still happening with Xena. Installed using kolla.

Assuming this is the freezer-schedular checked, /e/k/f-schedular/freezer.conf

Redacted sensible parts

[DEFAULT]
debug = False
log_dir = /var/log/kolla/freezer
client_id = controller
jobs_dir = /etc/freezer/scheduler/conf.d
os_username = admin
os_password = <correct-admin-password>
os_auth_url = http://<correct-fqdn-of-my-controller:35357/v3
os_project_name = admin
os_project_domain_name = Default
os_user_domain_name = Default

the FQDN of my controller was right. Running

curl http://<correct-fqdn-of-my-controller:35357/v3 -v

from within the freezer-scheduler docker-container gets a proper json response.
Also validated the admin password, it is correct.

Compared it with the /etc/kolla/admin-openrc.sh on the deployer. Password matches but maybe one of those is missing here?
export OS_REGION_NAME=RegionOne
export OS_AUTH_PLUGIN=password

Any update on this defect? I'm also affected by the same making Freezer unusable. This defect is almost 3 years old and there has not been one explanatory reply.

Also affects Ussuri and Victoria. Why is this defect left in a state of "undecided" for 4 YEARS?!

I also saw this bug in my deployment? Is there any workaround this error?

I was inspired by this git project https://github.com/unlenen/openstack-kolla-freezer in which OS_AUTH_URL docker environment variable is set.
I've hacked the kolla-ansible by adding `environment: "OS_AUTH_URL={{ openstack_auth.auth_url }}/v3"` in kolla_docker module and now freezer-scheduler works.

Here are my snippets:
 . in roles/freezer/tasks/check-containers.yml:
- name: Check freezer containers
  become: true
  kolla_docker:
    action: "compare_container"
    common_options: "{{ docker_common_options }}"
    name: "{{ item.value.container_name }}"
    image: "{{ item.value.image }}"
    volumes: "{{ item.value.volumes | reject('equalto', '') | list }}"
    dimensions: "{{ item.value.dimensions }}"
    environment: "OS_AUTH_URL={{ openstack_auth.auth_url }}/v3"
...
- name: Restart freezer-scheduler container
  vars:
    service_name: "freezer-scheduler"
    service: "{{ freezer_services[service_name] }}"
  become: true
  kolla_docker:
    action: "recreate_or_restart_container"
    common_options: "{{ docker_common_options }}"
    name: "{{ service.container_name }}"
    image: "{{ service.image }}"
    volumes: "{{ service.volumes | reject('equalto', '') | list }}"
    dimensions: "{{ service.dimensions }}"
+ environment: "OS_AUTH_URL={{ openstack_auth.auth_url }}/v3"

 . in roles/freezer/tasks/check-containers.yml:
- name: Check freezer containers
  become: true
  kolla_docker:
    action: "compare_container"
    common_options: "{{ docker_common_options }}"
    name: "{{ item.value.container_name }}"
    image: "{{ item.value.image }}"
    volumes: "{{ item.value.volumes | reject('equalto', '') | list }}"
    dimensions: "{{ item.value.dimensions }}"
+ environment: "OS_AUTH_URL={{ openstack_auth.auth_url }}/v3"
