Your error message says it cannot connect to port 23750. That's the kuryr-libnetwork default listen port. On 192.168.1.10, run:
lsof -iTCP -sTCP:LISTEN -P On my compute node, it outputs: COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME … kuryr-ser 1976 root 6u IPv4 30896 0t0 TCP localhost:23750 (LISTEN) So, you can see that kuryr is listening on 23750. If lsof does not list a process listening on 23750, then check if kuryr is up by running: systemctl status kuryr-libnetwork You can also try restarting it by running: systemctl restart kuryr-libnetwork I installed that service by following: https://docs.openstack.org/kuryr-libnetwork/queens/install/compute-install-ubuntu.html That is the queens install guide which might help you since zun has no install guide in pike. If you see it listening, you can try this command: telnet 192.168.1.10 23750 If it fails to connect, then try: telnet localhost 23750 If it works with localhost but not 192.168.1.10, then I think that means you need to tell docker to connect to localhost instead of 192.168.1.10. Can you get the commands at the following web page to succeed? https://docs.openstack.org/kuryr-libnetwork/queens/install/verify.html Jacob Burckhardt Senior Software Engineer [pdvWireless] From: Rania Adouni <raniaado...@gmail.com> Sent: Tuesday, November 20, 2018 2:02 PM To: openstack-dev@lists.openstack.org Subject: [openstack-dev] [zun] Failed to create Container [https://mailtrack.io/trace/mail/17bd40a2e38fcf449f8e80fdc1e7d9474dfbed19.png?u=2497697] Hi , I am starting to use zun on openstack pike , and when I try to lunch container with cirros image , I get this reason : Docker internal error: 500 Server Error: Internal Server Error ("legacy plugin: Post http://192.168.1.10:23750/Plugin.Activate: dial tcp 192.168.1.10:23750<http://192.168.1.10:23750/>: connect: connection refused"). you can find here the log on my compute node :https://pastebin.com/nZTiTZiV. some help with this will be great .
