Installing and configuring cloud-init on Ubuntu 26.04 makes it much easier to automate server setup, especially when working with cloud VPS systems, virtual machines, and home lab deployments.
If you’ve ever installed a fresh Ubuntu server and spent the next 20 minutes creating users, installing packages, configuring SSH keys, and adjusting networking manually, cloud-init can save yourself a lot of repetitive work.
Cloud-init is the initialization service used by most cloud platforms and virtual machine images. It reads configuration data during the first boot of a Linux system and automatically applies settings like hostname changes, user creation, SSH configuration, package installation, and startup commands.
