I'm still working on my previous error of the openstack appcontainer run error state:

I have Docker working behind a Proxy. As you can see in the Docker info i attach  to this mail. I tried to do the curl http://10.8.9.54:2379/health with the proxy environment variable and i got timeout error (without it the curl return the normal healthy state for the etcd cluster). So my question is if i'm having a problem with the proxy configuration and docker commands when i'm executing the openstack appcontainer run. And if you know any use case of someone working with Docker behind a proxy and Zun in the Openstack environment.

This is the outputh of 

# systemctl show --property Environment docker

Environment=HTTP_PROXY=http://10.8.7.60:3128/ NO_PROXY=localhost,127.0.0.0/8,10.8.0.0/16 HTTPS_PROXY=http://10.8.7.60:3128/

And this is the one of
