VyOS Automation with Cloud-init
Cloud-init for Network Automation with VyOS
Cloud-init is the industry-standard tool for automating the initialization of cloud instances. It enables administrators and DevOps teams to configure systems automatically at first boot, without manual intervention. With Cloud-init, you can define network settings, users, SSH keys, routing, and services through simple configuration files, ensuring every new device or VM is deployed consistently and ready for production in seconds.
Cloud-init allows you to
In enterprise and cloud networking, speed and repeatability are critical.
Automate Day-0 and Day-1 configuration of VyOS instances with routing, VPNs, firewall rules, and more.
Simplify multi-cloud deployments, applying the same initialization logic across AWS, Azure, GCP, and private clouds.
Ensure consistency at scale, avoiding human error while accelerating deployment timelines.
Integrate with orchestration tools like Terraform, Ansible, and Kubernetes for end-to-end automation.

How Cloud-init Works
Terraform uses configuration files written in HashiCorp Configuration Language (HCL) to describe the desired infrastructure state.˙
Define
Create a configuration file describing users, SSH keys, networking, and services.
Boot
When the VyOS instance launches, Cloud-init applies these configurations automatically.
Ready to Use
Within minutes, your router or firewall is online with the exact settings required for production.
