Rania,
For question #1, you can do the followings in *each compute node*:
* In your kuryr config file (i.e. /etc/kuryr/kuryr.conf), change the config
[DEFAULT]kuryr_uri . For example:
[DEFAULT]
kuryr_uri = http://192.168.1.10:23750
This config decides the IP address and port that the kuryr-libnetwork
process will listen to. By default, it listens to localhost which should be
good enough for most of the cases. Therefore, change it only if it is
necessary.
* In the file: /usr/lib/docker/plugins/kuryr/kuryr.spec , change the URL so
that docker will know how to connect to kuryr-libnetwork. The value must
match the kuryr_uri config above. Again, change it only if it is necessary.
Then, restart the docker and kuryr-libnetwork process. Let me know if it
still doesn't work for you.
For question #2, I remembered all processes are running in systemd, so you
can retrieve logs by using journalctl. For example:
$ journalctl -u kuryr-libnetwork > kuryr.log
$ journalctl -u zun-compute > zun-compute.log
$ journalctl -u zun-api > zun-api.log
Best regards,
Hongbin
