terraform-upcloud-faasd

This repo contains a Terraform plan for deploying a faasd instance on Upcloud using Terraform.

faasd, a lightweight & portable faas engine, is OpenFaaS reimagined, but without the cost and complexity of Kubernetes. It runs on a single host with very modest requirements, making it fast and easy to manage. Under the hood it uses containerd and Container Networking Interface (CNI) along with the same core OpenFaaS components from the main project.
