vlan plugin

Overview

The vlan plugin creates a vlan subinterface off an enslaved interface in the host network namespace and the container using a veth device. One end of the veth pair is placed inside a container and the other end is a subinterface off the master in the host network namespace. The host-local IPAM plugin can be used to allocate an IP address to the container. The traffic of the container interface will be routed through the interface of the host.

Example network configuration

{
	"name": "mynet",
	"cniVersion": "0.3.1",
	"type": "vlan",
	"master": "eth0",
	"mtu": 1500,
	"vlanId": 5,
	"ipam": {
		"type": "host-local",
		"subnet": "10.1.1.0/24"
	},
	"dns": {
		"nameservers": [ "10.1.1.1", "8.8.8.8" ]
	}
}
