[Antonio]

Hello:

I have installed Packstack, I have used the Rocky version, I followed https://www.rdoproject.org/install/packstack/

The problem is the following:

Error: Unable to retrieve the clusters.
Error: Unable to retrieve the stats.

The magnum-api.log:

Fix proposed to branch: master
Review: https://review.openstack.org/616509

Thanks for the report. I've proposed https://review.openstack.org/616509 with the fix to Packstack, and also https://review.openstack.org/616502 to puppet-magnum, to solve the mistake in the deprecation.

I've tested the fix locally, and magnum cluster-list now behaves as it should. Our test coverage in the gate is very limited for magnum, so if you find any other issue please do not hesitate to open more bugs :).

While the fix is merged, you can test it locally by adding "/v3" to the www_authenticate_uri parameter in /etc/magnum.conf, and then restarting the openstack-magnum-conductor and openstack-magnum-api services.

In queens version, I have found another bug when I tried to create a cluster.

Should I create another post or in this post?

    Replace deprecated puppet-magnum parameters

    The auth_uri parameter for magnum::keystone::authtoken was deprecated
    in [1], so we need to use the new www_authenticate_uri parameter.

    While at it, fix some manifest indentations.
