Hi Alejandro, Will it work if you change the kuryr config file to use port 5000? If yes, I will update the kuryr installation guide to use that port. *[neutron]* auth_url = http://controller: <http://controller:35357/>5000 Best regards, Hongbin On Mon, Apr 29, 2019 at 4:54 PM Alejandro Ruiz Bermejo < arbermejo0417@gmail.com> wrote:

Hi i've installed Openstack Queens on Ubuntu 18.04 and i'm following the Zun Installation Guide to deploy a container infrastructure. I'm following the steps to install kuryr-libnetwork (I've already installed docker on the compute node and it's working fine). The kuryr installation process had no errors but when i try to verify the operation as it's said in the guide

docker network create --driver kuryr --ipam-driver kuryr \ --subnet 10.10.0.0/16 --gateway=10.10.0.1 test_net

I'm Getting this error *Error* response from daemon: legacy plugin: Post http://10.8.9.54:23750/Plugin.Activate: dial tcp 10.8.9.54:23750: connect: connection refused

I tryed to find the error wit **journalctl -u kuryr-libnetwork

And this is the one at /usr/lib/docker/plugins/kuryr/kuryr.spec:

Btw compute node have connectivity with controller. I already have worked with the environment and launched kvm VMs on it

Can someone help troubleshoot this error??

*UPDATE1* I checked open ports on controller node and 23750 isn't open. I followed the directions at the guide, any recommendation?

Also in the compute node when i run systemctl status kuryr-libnetwork this is the output

*UPDATE2*

I tried the recommendations given by **hongbin034** and confirm that i had a problem with Keystone. when i run openstack token issue after exporting the neutron environment varibles i get the following output

Failed to discover available identity versions when contacting http://controller:35357. Attempting to parse version from URL. Could not determine a suitable URL for the plugin

I checked and the port 35357 isn't even open at the controller node. But at the controller node installation there isn't any step configuring such port
