Ipvlan PluginΒΆ
The Ipvlan plugin allows a virtual device that shares the physical capabilities and connectivity of a device on the host to be created in the container. The virtual device will have the same MAC address as the physical device. The kernel directs traffic to and from the virtualized device based on the IP address.
The following options are used to configure the plugin:
name
(string, required)The name of the network.
type
(string, required)ipvlan
master
(string, optional)The name of the host interface to use. Default: the default route interface.
mode
(string, optional)One of
l2
,l3
,l3s
. Default:l2
.mtu
(integer, optional)Set the MTU to the specified value. Default: chosen by the kernel.
ipam
(dictionary, required unless chained)The IPAM configuration to be used for this network.
Example
The following example would create a pod which contains an additional network
interface corresponding to an ipvlan
device which uses the eth1000
interface on
the host:
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
name: ipvlan0
spec:
config: '{
"cniVersion": "0.3.1",
"name": "ipvlan0",
"type": "ipvlan",
"master": "eth1000",
"mode": "l2",
"ipam": {
"type": "static",
"addresses": [
{
"address": "10.10.10.2/24",
"gateway": "10.10.10.1"
}
]
}
}'
