Dear All,

I am getting following error while trying to start the ubuntu container

Command: openstack appcontainer run --name containerA --net network=5guknet ubuntu ping 8.8.8.8

Error:

status_reason | Docker internal error: 500 Server Error: Internal Server Error ("legacy plugin: Post http://127.0.0.1:23750/Plugin.Activate: dial tcp 127.0.0.1:23750: connect: connection refused").

You might want to check the following:

1. if kuryr-libnetwork process is healthy and listens to port 23750 (do this in each compute node):

$ sudo systemctl status kuryr-libnetwork

$ sudo journalctl -u kuryr-libnetwork > kuryr.log

2. if there is anything blocking the port 23750

$ curl -X POST http://127.0.0.1:23750/NetworkDriver.GetCapabilities

If above doesn't help, you could paste me your kuryr-libnetwork's log (sudo journalctl -u kuryr-libnetwork > kuryr.log) and config file (/etc/kuryr/kuryr.conf).

Secondly, with Heat Template:

heat_template_version: 2015-04-30

resources:

the_resource:

    type: OS::Zun::Container

    properties:

      cpu: 4

      image: ubuntu

      image_pull_policy: "ifnotpresent"

      interactive: true

      memory: 2048

      name: "ubuntu16"

      command: "ping 8.8.8.8"

      networks: [{"network": 5guknet}]

      restart_policy: "no"

The command I can see on the appcontainer show is : command           | [u'p', u'i', u'n', u'g', u' ', u'8', u'.', u'8', u'.', u'8', u'.', u'8']

This looks like a bug. I created a ticket for this: https://storyboard.openstack.org/#!/story/2005469

Please advise how to resolve the two issues.

Kind Regards,

Navdeep
