Using a fresh Tacker stack from Stable/Ocata and the examples from https://docs.openstack.org/tacker/lat..., I could load VNFDs and NSD per the examples, but attempts to Deploy the NS always fail with an "EndpointNotFound: public endpoint for workflowv2 service not found exception". Private attempts with a much simpler VNFD and NSD also failed in the same spot.

Tacker.log excerpt as follows:

Thanks for the quick answer. I certainly thought I installed Ocata. Here is the snippet from my local.conf and the resulting versions. Is there any chance the stable/ocata tags/versions are misaligned?

[[local|localrc]]
enable_plugin heat https://git.openstack.org/openstack/heat stable/ocata
enable_plugin tacker https://git.openstack.org/openstack/tacker stable/ocata
...
run stack.sh 
…
ubuntu: ~$ tacker –version
0.9.0
ubuntu: ~$ heat –version
1.8.1
ubuntu: ~$ mistral –version
3.0.2

stable/ocata tag for tacker is 0.7.0 meaning 0.9.0 (not released yet) is a dev version https://github.com/openstack/releases... I would just unstack, git checkout origin/stable/ocata in devstack repo and stack again.Or sorry for spam,just use kolla-ansible :)

didn't have any luck getting that to work ...is there a syntax to explicitely give a version number via local.conf so that it the plugin is as desired ... LIKE:

[[local|localrc]] enable_plugin tacker https://git.openstack.org/openstack/tacker/0.7.0 (https://git.openstack.org/openstack/t...)

No idea about devstack sorry, just pointed out that was failing due wrong version. https://docs.openstack.org/devstack/l...

Btw, doesnt make sense use devstack for stable releases unless working for a bug fix

Hi,

From what I see in the logs, tacker version being used is current master (Pike release).

Ocata does not require workflowv2 (mistral endpoints) to work. VIM monitoring through Mistral was implemented during Pike release.

Check this part of code where do the authentication and fails in your case is not present in Ocata branch: https://github.com/openstack/tacker/blob/master/tacker/mistral/mistral_client.py

class MistralClient(object):
    """Mistral Client class for NSD"""

    def __init__(self, keystone, auth_token):
        endpoint = keystone.session.get_endpoint(
            service_type='workflowv2', region_name=None)

        self.client = mistral_client.client(auth_token=auth_token,
mistral_url=endpoint)

Please, make sure to checkout or install stable/ocata packages.

Regards
