Macvlan
===============
How to use it :
-------------
* Enable macvlan in `group_vars/k8s-cluster/k8s-cluster.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:
```
all:
hosts:
node1:
ip: 10.2.2.1
access_ip: 10.2.2.1
ansible_host: 10.2.2.1
macvlan_interface: ens5
```
Issue encountered :
-------------
- Service DNS
reply from unexpected source:
add `kube_proxy_masquerade_all: true` in `group_vars/all/all.yml`
- Disable nodelocaldns
The nodelocal dns IP is not reacheable.
Disable it in `sample/group_vars/k8s-cluster/k8s-cluster.yml`
```
enable_nodelocaldns: false
```
