CNI / IPVLAN not creating an interface

Nomad
1

I have created a mynet IPVLAN interface with the expectation that it should create me a new interface for the deployed task. The task gets a port on the IP associated with the physical interface, not a new interface and it is not routable.

There are no errors in the logs so I’m a little confused as to where to go next.

{
	"cniVersion": "0.4.0",
	"name": "mynet",
	"plugins": [
		{
			"type": "ipvlan",
			"master": "ens3",
	                "ipam": {
		          "type": "host-local",
		          "ranges": [
			    [
			      {
		  		"subnet": "10.0.3.0/24",
				"rangeStart": "10.0.3.10",
				"rangeEnd": "10.0.3.15",
				"gateway": "10.0.3.1"
			      }
			    ]
		          ],
			  "routes": [
			    { "dst": "0.0.0.0/0" }
			  ],
		          "dataDir": "/run/my-orchestrator/container-ipam-state"
			}
                },
		{
			"type": "portmap",
			"capabilities": {
				"portMappings": true
			},
			"snat": true
		}
	]
}

Interface:

2: ens3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9001 qdisc mq state UP group default qlen 1000
    link/ether 12:2b:d0:6e:06:57 brd ff:ff:ff:ff:ff:ff
    altname enp0s3
    inet 10.0.3.13/24 metric 100 brd 10.0.3.255 scope global dynamic ens3

Job specification

  datacenters = ["dc1"]

  group "cni_test" {

    count = 1

    restart {
      attempts = 1
    }

    network {
      mode = "cni/mynet"
      port "http" {
        to = 80
      }
    }

    task "cni_test" {

     driver = "docker"
      
      config {
        image = "nginx"
        ports = ["http"]
      }
    }
  }
}

Is there something I am missing to get this to work?
