If your system is using netplan for network configuration, change settings in “/etc/netplan/50-cloud-init.yaml”:
DHCP:
jonas@kube-c1-n3:~$ cat /etc/netplan/50-cloud-init.yaml network: ethernets: enp0s3: addresses: [] dhcp4: true version: 2 jonas@kube-c1-n3:~$ sudo netplan apply
Static IP:
jonas@kube-c1-n3:~$ cat /etc/netplan/50-cloud-init.yaml network: ethernets: enp0s3: addresses: [192.168.10.103/24] gateway4: 192.168.10.1 dhcp4: no version: 2 jonas@kube-c1-n3:~$ sudo netplan apply
Note that “gateway4” should only be set for the default route interface.
