"'min' is undefined' while running Rally Certification Task

[Oleksandr Kyrylchuk]

Hi all,

I tried to run Rally Certification Task. For 'authentication' and 'nova' services it worked ok, but for others failed.

Here's an example for Cinder:

$ docker exec -it 0505a8acc430 rally task start /tmp/rally_tests/certification/openstack/task.yaml --task-args '{"service_list": ["cinder"], "tenants_amount": "1", "image_name": "^(cirros.*uec|TestVM)$", "controllers_amount": "1", "glance_image_location": "", "computes_amount": "2", "use_existing_users": false, "flavor_name": "m1.tiny", "smoke": true, "users_amount": "1", "network_amount": "1", "storage_amount": "1"}'

'min' is undefined

Failed to load task
------------

Rally is installed on instance booted within MOS 7.0 cloud. All required access to nodes is provided.

What does 'min' stands for? And how to solve this issue?

You are trying to use certification task from 0.1.2 at older release(0.1.1 for example). This older release doesn't include change which patches jinja2 environment with min max methods

[Andriy Kurilin (andreykurilin)]

required change for using min/max methods in jinja templates - https://github.com/openstack/rally/commit/4eab35d6ca910d204ac4a7def7c664c85982ea22
