I'm using Docker Swarm with the contiv/v2plugin:0.1 plugin:

netctl is on version 1.0.0.

Short update.

I just found out, that currently only Engine 1.12.x & Swarm 1.2.5 is supported as shown here http://contiv.github.io/documents/support/supportmatrix.html. Do you guys have any plans when support for 17.03.1-ce and the newest Docker Swarm version (I guess currently its 1.2.6) will be added?

Thanks

I get the same problem yet, Do you have any solution?

docker Version: 17.07.0-ce-rc3 API version: 1.31 Go version: go1.8.3

Hi @iiwawe,

Unfortunately not really - its still not working. A Contiv developer told me to follow v2plugin/README.md, especially point 5.2 seems to be important because there you match the contiv used labels (-tag policylabel) with the docker network create XX used -o contiv-tag=policylabel. This way Contiv should be able to align the Contiv internal network configuration with the docker network configurations the background.

Regards, Philip

[gkvijay]

@iiwawe, @PhilipSchmid, for docker swarm-mode, the contiv workflow was changed. Netctl commands used to create a network doesn't create a docker network. Once the networks and groups are configured using netctl command, you should use docker workflow to create docker network and run docker containers. This was a requirement for contiv to be certified as a docker plugin. The contiv-tag used in docker network create maps it to a network or group created by netctl command

[iiwawe]

@PhilipSchmid @gkvijay Thanks for your reply

before create a docker network, i must create a network by netctl command, is that mean ? when create network by command "netctl network create contiv-net-1 -s 200.1.1.1/24 -g 200.1.1.200", i got error "ERRO[0015] Error response from daemon: legacy plugin: plugin not found", if i run the command again, network contiv-net-1 is create succeed. and when i create group by "netctl group create -p p1 -tag policylabel contiv-net-1 group1" i get the same error. i should do something before this?

Thanks
