Hi Hyunsun,

From you log:

2017-07-11 09:21:20.221 12 ERROR kuryr_libnetwork.utils [-] Unexpected error happened: Subnet with pool f96b5ff6-4065-4eed-9854-3a54122f90c9 does not exist.: KuryrException: Subnet with pool f96b5ff6-4065-4eed-9854-3a54122f90c9 does not exist.

It looks like failed in L1560:
1487 @app.route('/IpamDriver.RequestAddress', methods=['POST'])
1488 def ipam_request_address():
…
1559     if not any(subnet) and not is_gateway:
1560         raise exceptions.KuryrException(
1561             ("Subnet with pool {0} does not exist.").format(pool_id))

This problem looks like hit the following bug I hit before:
https://bugs.launchpad.net/kuryr-libnetwork/+bug/1677316

libnetwork has a bug here, I am not sure that bug has fixed in your docker:
https://github.com/docker/libnetwork/issues/1702

I did not test more at that time, because it did not released at that time.
Let me double check if it has fixed in the latest docker and update in Launchpad this week.

Thanks.

Regards,
Liping Mao

Here it is.

[DEFAULT]
bindir = /usr/libexec/kuryr
capability_scope = global
log_dir = /var/log/kuryr
log_file = kuryr.log

Can you help to attach your kuryr.conf configuration file?

主题: [openstack-dev] [kuryr] Subnet pool does not exist error

Hi all,
I’m getting an exception when creating a service with Kuryr network.

I created and installed kuryr plugin by building plugin rootfs from the source code.
Here’s what I did after that.


$ sudo docker network create --driver=kuryr/libnetwork2:latest --ipam-driver=kuryr/libnetwork2:latest --subnet=10.10.10.0/24 --gateway=10.10.10.1 kuryr-net

$ sudo docker service create --name redis --network kuryr-net redis:3.0.6
Neutron does not get any request from Kuryr.
Here’s the error message collected from /var/log/kuryr/kuryr.log.

2017-07-11 09:21:06.950 12 INFO kuryr_libnetwork.controllers [-] Creating subnetpool with the given pool CIDR

2017-07-11 09:36:28.121 13 ERROR kuryr
I tried creating a network with existing Neutron subnetpool as below, but the result was the same.
$ sudo docker network create --driver=kuryr/libnetwork2:latest --ipam-driver=kuryr/libnetwork2:latest --subnet=10.10.10.0/24 --gateway=10.10.10.1 --ip-range=10.10.10.0/24 -o neutron.pool.name=kuryr --ipam-opt=neuton.pool.name=kuryr kuryr-net

Any suggestion?
