How to Install OpenFaaS on Windows 11

OpenFaaS is a framework for building serverless functions and microservices. In this guide, we will see how to install OpenFaaS on Windows 11.

Prerequisites

Before you begin, make sure you have the following:

• Windows 11 installed on your machine.
• Docker Desktop installed and running. You can download it from https://www.docker.com/products/docker-desktop.
• Git installed. You can download it from https://git-scm.com/downloads.

Step 1: Clone OpenFaaS repository

To clone the OpenFaaS repository, open the command prompt or Windows Terminal and run the following command:

git clone https://github.com/openfaas/faas.git

This will clone the repository to your current working directory.

Step 2: Install OpenFaaS CLI

The OpenFaaS CLI allows you to interact with the OpenFaaS cluster. To install it, run the following command:

.\faas-cli install

This will download the OpenFaaS CLI executable and install it.

Step 3: Start OpenFaaS

To start OpenFaaS, go to the cloned faas directory and run the following command:

.\deploy_stack.ps1 -g

This will start the OpenFaaS cluster using Docker Compose. -g option tells Docker Compose to run the cluster in global mode, which ensures that every node in the Docker swarm runs a replica of the service.

Step 4: Verify installation

To verify that OpenFaaS is running, run the following command:

.\faas-cli version

This should show you the version of the OpenFaaS CLI and the OpenFaaS Gateway.
