TASK [keystone : Check keystone containers] does not works with Jinja 2.9.5

[Manik Sidana]

While running kolla-ansible deploy, I got the below error
TASK [keystone : Check keystone containers] ************************************
skipping: [localhost] => (item={'key': u'keystone-fernet', 'value': {u'enabled': False, u'image': u'kolla/centos-binary-keystone-fernet:4.0.0', u'group': u'keystone', u'volumes': [u'/etc/kolla//keystone-fernet/:/var/lib/kolla/config_files/:ro', u'/etc/localtime:/etc/localtime:ro', u'kolla_logs:/var/log/kolla/', u'keystone_fernet_tokens:/etc/keystone/fernet-keys'], u'container_name': u'keystone_fernet'}})
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TemplateRuntimeError: no test named 'equalto'
fatal: [localhost]: FAILED! => {"failed": true, "msg": "Unexpected failure during module execution.", "stdout": ""}

Reason: 'equalto' is not present in Jinja2 2.9.5.
kolla-ansible has below condition on Jinja2
Jinja2!=2.9.0,!=2.9.1,!=2.9.2,!=2.9.3,!=2.9.4,>=2.8 # BSD License (3 clause)
Due to this, Jinja2.9.5 got installed on my System and I had to downgrade Jinja2 to 2.8 using pip install Jinja2==2.8

Environment details:
kolla-mitaka
Ubuntu 14.04
CentOS binary docker images
ansible version 2.2.1

i think equalto exist since jinja 2.8 [0]. Are u sure you are using 2.9.5?

[Manik Sidana (manik019)]

Yes, I used 2.9.5 and got this error. It went through when I downgraded to Jinja2 2.8

[Jeffrey Zhang (jeffrey4l)]

jinja2 have this function. i tested it, it works.

[Manik Sidana (manik019)]

Did you try kolla-ansible deploy with 2.9.5 ?
Although "equalto" was added in version 2.8, but I got this error with 2.9.5.

Also, I noticed that global-requirements.txt is excluding 2.9.0 - 2.9.4 versions of Jinja2. https://github.com/openstack/requirements/blob/master/global-requirements.txt#L77

[Manik Sidana (manik019)]

I think its better to exclude 2.9.5 since this is a development version. The highest stable version is 2.9.
Please suggest

The 'equalto' test does seem to exist in Jinja2 2.9.5: https://github.com/pallets/jinja/blob/09f8b2b2d1cfca7e5b231cf3773bef2a952b6312/jinja2/tests.py#L181

I'm using it in Jinja 2.9.5 right now.

[julien du Bois (masterdubs)]

same issue with 2.9.5 fixed with pip install https://github.com/pallets/jinja/zipball/master

[Eduardo Gonzalez (egonzalez90)]

Were you able to reproduce the issue? Jinja2.9.5 have equalto tests as referenced by #8.

Please, provide more information, an output of ``pip freeze`` on kolla deploy node.
