Netplan YAML Generator for Ubuntu: Static IP Files Without Syntax Errors

Netplan files are short, but YAML is strict about indentation, and the way you set a default gateway changed in Ubuntu 22.04. One wrong space and the network doesn’t come up. The generator below writes the file for you.

Why use a generator

• No syntax errors – indentation and lists are always correct
• Right syntax for your release – routes: on 22.04+ and gateway4: on 20.04 and older
• Validation – it warns when the gateway is outside the subnet or DNS is missing
• Safe apply steps – backup, chmod 600 and netplan try with automatic rollback

Prefer the terminal? See the interactive bash script that does the same on the server itself.

• #netplan
• #Static IP
• #ubuntu
