gateway ip options are None in swarm mode

[LipingMao]

Hi Team,

When I use lagency libnetwork remote plugin, for example, I created a network with gateway ip as follow:
docker network create --driver kuryr --ipam-driver kuryr --subnet 10.225.17.0/24 --gateway 10.225.17.1 --ip-range 10.225.17.0/24 limao_swarm_kuryr

When libnetwork call kuryr ipam driver "/IpamDriver.RequestAddress" request address for gateway ip, it will have Options {"RequestAddressType": "com.docker.network.gateway"}.

But when I use docker swarm mode in 1.13.1, it do not has this Options.

Is this by design or a bug?

Thanks for your help.

@LipingMao That should have been fixed by moby/swarmkit/pull/1805.
I think docker 17.03 has the fix.

Thanks for your quick response, I see the pull-request you posted is to fix the problem in RequestPool, my problem is related with RequestAddress.

When I not use Swarm mode, when it RequestAddress for gateway ip, it will has options: {"RequestAddressType": "com.docker.network.gateway"}. But in Swarm mode, the Options are empty.

I'm not familar with swarmkid, but when I try to search "RequestAddress" in swarmkid, I see it did not pass options to RequestAddress, Did I miss anything? Thanks.

784 gwIP, _, err := ipam.RequestAddress(poolID, net.ParseIP(ic.Gateway), nil)

Oh I see. I will take a look.

@aboch thanks for the quick fix.
One quick question: is this fix possible to be backport to stable branch? or it will be only in later release?

[aboch]

At the moment we have not planned to backport it.

Is this related to docker/docs#1636 ?
It seems we can't define gateway (and other options) when using swam mode ?
How do we set the macvlan settings then?
