How do I create a YAML file in order to set a static IP for my /etc/netplan directory? Server 18.04 LTS

Question

I currently do not have any YAML files in my /etc/netplan directory than I can edit in order to set a static IP for my Ubuntu 18 server. I have tried:

sudo netplan generate

It returns no errors but there is also no new files (or any files for that matter) created under /etc/netplan. Can I use nano to create a file a save it with a .yaml extension and still use

sudo netplan apply

in order to update my Ethernet interface settings?

Solution

That is exactly what I suggest that you do. Here is a sample file to get started: Can't change Ubuntu 17.10 to use a static IP

Of course, substitute your exact details here. Also, indentation, spacing, etc. are crucial. Proofread carefully.
