How to Install OpenFaaS on Linux Mint Latest

OpenFaaS is a serverless framework for building and deploying functions as microservices. It is written in Golang and provides a pluggable architecture that allows developers to use language-specific runtimes, such as Node.js, Python, and others.

This tutorial will guide you through the steps to install OpenFaaS on Linux Mint Latest.

Prerequisites

• Linux Mint Latest
• Docker
• Docker Compose

Step 1 - Install Docker

Docker is a containerization platform that allows you to run applications in isolated containers. To install Docker on Linux Mint Latest:

sudo apt update
sudo apt install docker.io

After installation, verify that Docker is running by running the following command:

sudo systemctl status docker

Step 2 - Install Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. To install Docker Compose on Linux Mint Latest:

sudo apt install docker-compose

Verify that Docker Compose is installed by running the following command:

docker-compose version

Step 3 - Install OpenFaaS

To install OpenFaaS, you need to clone the OpenFaaS repository from GitHub. Run the following commands to clone the repository and switch to the master branch:

git clone https://github.com/openfaas/faas.git
cd faas
git checkout master

Next, follow the steps below to configure and deploy OpenFaaS:

1. Create a file named .env in the faas directory with the following contents:

   cp .env.example .env
   

2. Edit the .env file and set the PASSWORD variable to a strong password:

   vi .env
   

   PASSWORD=mystrongpassword
   

3. Create a new directory named stacks:

   mkdir -p ./stacks
   

4. Start the OpenFaaS stack:

   docker-compose up -d
   

   This command will start the OpenFaaS stack in detached mode, which means that it will run in the background.

5. Verify that the OpenFaaS stack is running:

   docker ps
   

   You should see the following containers running:

   CONTAINER ID   IMAGE                        COMMAND                  CREATED          STATUS          PORTS                     NAMES
   e9a520f27c36   openfaas/gateway:0.25.2      "./entrypoint.sh"        11 minutes ago   Up 11 minutes   0.0.0.0:8080->8080/tcp   gateway
   1ee64ab71b56   openfaas/faas-swarm:0.11.1   "/sbin/tini -- /usr…"   11 minutes ago   Up 11 minutes   2375/tcp                  faas-swarm
   

Step 4 - Configure the OpenFaaS CLI

The OpenFaaS CLI is a command-line tool that allows you to interact with the OpenFaaS gateway. To configure the CLI on Linux Mint Latest:

1. Install the CLI by running the following command:

   sudo curl -sSL https://cli.openfaas.com | sudo sh
   

2. Login to the OpenFaaS gateway:

   echo $PASSWORD | faas login --gateway http://127.0.0.1:8080 -u admin --password-stdin
   

   This command uses the PASSWORD you set earlier to log in to the OpenFaaS gateway.

3. Verify that the CLI is configured correctly:

   faas version
