Extra CNI args in network config

Supported arguments

The NV-IPAM plugin supports the following args in network config:

Argument Type Description
ips []string Request static IPs from the pool
poolNames []string, max len is 2 Name of the pools to be used for IP allocation. _The field has higher priority than ipam.poolName
poolType string Type (ippool, cidrpool) of the pool which is referred by the poolNames. The field has higher priority than ipam.poolType
allocateDefaultGateway bool Request to allocate pool's default gateway as interface IP address for the container. Pool must have the gateway when this argument is used. The argument can't be used together with static IP request or with allocating IP of specific index.
allocateIPWithIndex int Request to allocate pool's IP with the given index as interface IP address for the container. The argument can't be used together with static IP request or with allocating the gateway IP.
