Creating a reusable VM template in Proxmox using Cloud-init can streamline VM deployments significantly. This post covers the step-by-step process to set up a cloud-init-enabled VM template using Ubuntu for Proxmox.
Creating a VM template in Proxmox using cloud-init can streamline VM deployments significantly. This post covers the step-by-step process to set up a cloud-init-enabled VM template using Ubuntu for Proxmox.
Proxmox supports Cloud-init, a tool that allows the automatic configuration of virtual machines right after they are provisioned. This includes setting up networking, SSH keys, and other initial settings.

In this guide, we'll create a VM template with Cloud-init enabled, allowing for rapid deployment of pre-configured VMs.

The template can now be used to spawn new instances with custom configurations by providing the necessary Cloud-init parameters. This is particularly useful for deploying multiple instances with consistent baseline configurations quickly.
