We can only create kuryr local network in docker swarm 1.13

[Liping Mao]

Environment:
RHEL + Docker 1.13.1

Reproduce steps:
1. build docker cluster in swarm mode.
2. Create kuryr network in one node, kuryr network will be created as local scope, and we can't see it in other nodes.

[root@limaonew-1 ~]# docker network create --driver=kuryr --ipam-driver=kuryr --subnet 10.225.18.128/26 --gateway 10.225.18.129 --ip-range 10.225.18.128/26 -o neutron.net.uuid=5b231d26-edd8-4536-90e6-be446530b86e limao_input
09e526fb654c119fa27b38ef302b84088442ca57de8e793aafac30045c638c6e
[root@limaonew-1 ~]# docker network ls
NETWORK ID NAME DRIVER SCOPE
2b3ad1da7716 bridge bridge local
5107a04d5722 docker_gwbridge bridge local
e00cfceecd74 host host local
imaapjuh3iy0 ingress overlay swarm
09e526fb654c limao_input kuryr local
7fc4c8ab228c none null local

[root@limaonew-2 ~]# docker network ls
NETWORK ID NAME DRIVER SCOPE
f7c6ca2ca6ba bridge bridge local
10d47c92eb61 docker_gwbridge bridge local
1ec28a86071b host host local
imaapjuh3iy0 ingress overlay swarm
747dfd34ce12 none null local

When we run kuryr as global scope, there is the following error:
Error response from daemon: rpc error: code = 3 desc = legacy plugin kuryr of type NetworkDriver is not supported in swarm mode

I see comments in https://github.com/docker/docker/issues/24569.
Looks like only plugin v2 works in swarm mode.

Based on the comments is https://github.com/docker/docker/issues/24569, kuryr must be implemented as managed plugin

[Liping Mao (limao)]

Hi Irena,

Yes, I'm trying to see how to make kuryr-libnetwork works as a managed plugin.

Thanks.

@irenab

I tried docker swarm with pluginv2, it can work with local scope, but still can't work with global scope. Open the following issue in libnetwork to trace this:
https://github.com/docker/libnetwork/issues/1699

[Liping Mao (limao)]

Currently Kuryr-libnetwork will not work with swarm mode:
https://github.com/docker/docker/issues/32604

From aboch:
At swarm network creation, the pool allocation, from the IPAM driver's default global address space will be done by the swarm allocator.
When the network will be created on the node, the pool allocation will be requested on the node from the IPAM driver's default local address space.

    2. add config.json for v2plugin
    3. Add scripts to build v2plugin rootfs
    4. Update devstack to use v2plugin
