faasd for Microsoft Azure

This repo contains a Terraform Module for how to deploy a faasd instance on Microsoft Azure 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.

What's a Terraform Module?

A Terraform Module refers to a self-contained packages of Terraform configurations that are managed as a group. This repo is a Terraform Module and contains many "submodules" which can be composed together to create useful infrastructure patterns.

How do you use this module?

This repository defines a Terraform module, which you can use in your code by adding a module configuration and setting its source parameter to URL of this repository:

provider "azurerm" {
  features {}
}

resource "azurerm_resource_group" "faasd" {
  name     = "FaasdResources"
  location = "West Europe"
}

resource "azurerm_virtual_network" "faasd" {
  name                = "FaasdNetwork"
  address_space       = ["10.0.0.0/16"]
  location            = azurerm_resource_group.faasd.location
  resource_group_name = azurerm_resource_group.faasd.name
}

resource "azurerm_subnet" "internal" {
  name                 = "internal"
  resource_group_name  = azurerm_resource_group.faasd.name
  virtual_network_name = azurerm_virtual_network.faasd.name
  address_prefixes     = ["10.0.2.0/24"]
}

module "faasd" {
  source = "github.com/jsiebens/terraform-azurerm-faasd"
  
  name                = "faasd"
  resource_group_name = azurerm_resource_group.faasd.name
  location            = azurerm_resource_group.faasd.location
  subnet_id           = azurerm_subnet.internal.id
  public_key          = file("~/.ssh/id_rsa.pub")
}
