Adding a VLAN interface with Netplan

Follow the below to add a VLAN through Netplan on a Ubuntu server

1. Open the Netplan Configuration File:

sudo nano /etc/netplan/01-network-manager-all.yaml

2. Edit the File with the Correct Configuration:

network:
  version: 2
  ethernets:
    eno1:
      dhcp4: yes
  vlans:
    vlan50:
      id: 50
      link: eno1
      gateway4: 192.168.50.1
      nameservers:
        addresses: [192.168.1.9, 192.168.1.8]

3. Apply the Configuration:

sudo netplan apply

4. Verify the Configuration:
ip a

You should now see the vlan50 interface.

 

Docker MACVLAN example:

docker network create -d macvlan \
  --subnet=192.168.50.0/24 \
  --gateway=192.168.50.1 \
-o parent=eno50 \
  DockNet

Note: You have to restart docker after editing the netplan.
