Bug Description

Hi, I tried to install Openstack Train with neutron calico driver and getting the following exception:
ERROR neutron.manager [-] Plugin ‘calico’ not found.
Could someone help me understand if calico driver is ready for Openstack Train or Stein which is running with Python3.
If it's still not ready and not working after few years, so what is the developing and QA cycles in calico for Openstack? And what is the solution? Or ETA for solution? Maybe someone can advise for better solution than going with calico to Production and latest Openstack release?
Thanks..

Vasili, the problem here is Python 3, which we don't yet support. Can you try running (the whole of OpenStack, plus Calico) with Python 2 instead?

Vasili (vasili.namatov) wrote on 2019-12-17:

I installed Openstack Queens with Calico successfully and it works fine.
BUT We have to move to Python3 due to since beginning of 2020 the python2.x will be EOL and will not be supported anymore.

I need calico driver working on Openstack Train which is fully working with python3.
I tried to fix some issues but there are many.
Could you advise if calico Driver is going to continue to work with Openstack. And if not so we have to look for alternatives for calico driver. Its not so serious for the component which is working with openstack not to be ready for latest openstack version and python3.

Python3 available since stein, since April there is no working calico plugin with python3?

Best,
Vasili

Vasili, I completely agree with you, and I am trying to schedule time for the work needed for it. BTW, you can see the work that I have started, at https://github.com/neiljerram/networking-calico/commits/ci-fixups. (The next class of problems is where the test code expects normal strings and gets b"..." strings instead.)

Regarding the PyPI declaration - yes, I'm sorry, this is wrong. I did previously think that our code was already Python 3 compatible, but I'm afraid I misunderstood the situation.

I will try to fix the PyPI declaration for the next release...

FYI: Running openstack (master) with python2 will not work for long any more since in ussuri we dropped support for it:

https://governance.openstack.org/tc/goals/selected/ussuri/drop-py27.html

Most projects did not willingly broke python2 compatibility but dropped python2 gate jobs, so it's only a question of time when it will become actually broken.

On the other hand the train release is still supposed to work with python2, so that maybe a workaround until calico makes the changes mentioned by Neil above.

Thanks Bence. FYI, in Neutron I believe https://review.opendev.org/#/c/691874/ has already broken Python 2, so the ship has now sailed for almost all new OpenStack deployments (excepting any that are Swift-only, or still using nova-net if that is possible).

Thanks Neil, so not yet in 3.11 release...
Waiting for the next one..

As discussed I'm trying to fix some peaces of code by myself and now neutron-server service doesn't fails, but I assume that it didn't load some data as expected and maybe that why it not failed. Meanwhile it's just a theory. :)

Could you advise if I need to open the new bugs for each and each errors I found or I can put all my findings here in this bug?

Just opened another one:

python3 support is completely up to the networking-calico project.
From the perspective of the neutron project, there is nothing to do, so I am marking it as Invalid in "neutron".
All other associated projects (OpenStack Community Project, Python Packaging Index, Ubuntu and Ubuntu Server) are unrelated as they are projects which develop/maintain networking-calilo.

Hi Bence,

In addition to your comment:

I tried to install Stein or Train and I see that neutron is already based python3.
You have some proper way/guyide how you can install neutron in stein release by using python2.7?

Stein and Train components are essentially written on python3 in those releases.
Looks like its nothing to do with the components which are already written on python3 on those releases.
I asked today the community about that, let's wait a few days for the answer:

Looks like there is no workarounds for calico beginning from Stein! The other hand is to wait ages for calico python3 support or try to find the alternatives. In May 2020 we already will have Ussuri and Calico is still not in Stein.

Python support

The Stein and Train releases of Ubuntu OpenStack is Python 3 only; all Python 2 packages have been dropped in Stein and Train.

As mentioned here:
TRAIN https://wrestlingpenguins.wordpress.com/2019/10/23/openstack-train-for-ubuntu-18-04-lts/
STEIN https://javacruft.wordpress.com/2019/04/17/openstack-stein-for-ubuntu-18-04-lts/

Python 3 support was added in Calico v3.15 https://docs.projectcalico.org/release-notes/#v3150

The master networking-calico code now supports Python 3, and no longer Python 2. There is a 'release-v3.15-python2' branch that still supports Python 2, but we are hoping that maintenance of that branch can now be short-lived.

Changed in networking-calico:
status:	New → Fix Released
