# Macvlan
2019-12-04 15:22:57 +00:00
## How to use it
* Enable macvlan in `group_vars/k8s_cluster/k8s_cluster.yml`
2019-12-04 15:22:57 +00:00
```yml
...
kube_network_plugin: macvlan
...
```
* Adjust the `macvlan_interface` in `group_vars/k8s_cluster/k8s-net-macvlan.yml` or by host in the `host.yml` file:
2019-12-04 15:22:57 +00:00
```yml
all:
hosts:
node1:
ip: 10.2.2.1
access_ip: 10.2.2.1
ansible_host: 10.2.2.1
macvlan_interface: ens5
