Comment 2 for bug 1782400

About the log, since we are using systemd, the log needs to be retrieved by using journalctl. For example:

  # journalctl -u zun-compute > zun-compute.log
  # journalctl -u zun-api > zun-api.log
  # journalctl -u zun-wsproxy > zun-wsproxy.log

Or you can follow the logs in real time:

  # journalctl -f -u zun-*

Note: if you want debug information in the log, you can set debug=True in your Zun config file.

Another trick for debugging is to add the '--debug' flag in the command you run. For example:

  $ openstack --debug appcontainer exec --interactive container2 /bin/sh
