Configuring Static IP in Ubuntu 18.04.2 LTS (Bionic Beaver)

The method of configuring static ip in Ubuntu 18.04.2 LTS is different from its previous variants. Previously it was to configure in /etc/network/interfaces file, however in Ubuntu 18.04.2 LTS, it is setup in /etc/netplan/50-cloud-init.yaml file.

root@ubuntu:/etc/netplan# ls
50-cloud-init.yaml
