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

This is the relevant content of my /etc/kuryr/kuryr.conf

*[DEFAULT]*

bindir = /usr/local/libexec/kuryr

*[neutron]*

www_authenticate_uri = http://controller:5000

auth_url = http://controller:35357

username = kuryr

user_domain_name = default

password = 123

project_name = service

project_domain_name = default

auth_type = password


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

http://conrtoller:23750


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
