I see the release note 8afd1b7 Docker 1.13 swarm-mode support for contiv

Command to create a contiv network netctl --netmaster http://172.20.0.113:9999 network create --subnet=10.1.2.0/24 contiv-net

Should I start the netplugin daemon first before create a contiv network?

@rootsongjc, docker swarm-mode supports v2 plugins. You need to install contiv's v2 plugin

1. start etcd on the host
2. docker plugin install contiv/v2plugin:1.0.0-beta.3 iflist=
3. docker plugin ls This starts bothnetplugin and netmaster in the v2plugin. I will document the steps and add it to the repo soon

@gkvijay Thanks, I can build the v2plugin with this command belowing.

bash scripts/v2plugin_rootfs.sh

The rootfs at install/v2plugin/rootfs ，then docker network create contiv/v2plugin install/v2plugin/

I got it working with the following commands:

docker plugin install contiv/v2plugin:1.0.0-beta.6
Plugin "contiv/v2plugin:1.0.0-beta.6" is requesting the following privileges:
 - network: [host]
 - mount: [/etc/openvswitch]
 - mount: [/var/log/openvswitch]
 - mount: [/var/run]
 - mount: [/lib/modules]
 - capabilities: [CAP_SYS_ADMIN CAP_NET_ADMIN CAP_SYS_MODULE]
Do you grant the above permissions? [y/N] y
...
...
service netmaster restart
service netplugin restart

After the service restarts, I was able to create networks using netctl:

netctl net create -p 123 -e vlan -s 192.168.123.0/24 prod-docker
