Installing OpenFaaS on Elementary OS Latest

OpenFaaS is a popular framework for building serverless functions based on Docker containers. It is written in Go and provides a scalable and flexible way to build APIs and microservices. In this tutorial, we will guide you through the process of installing OpenFaaS on Elementary OS Latest.

Prerequisites

Before you begin, make sure you have the following prerequisites in place:

  • Elementary OS Latest installed on your system
  • Docker installed and running
  • Git installed
  • kubectl installed

Installing OpenFaaS

  1. Clone the OpenFaaS repository
git clone https://github.com/openfaas/faas.git
cd faas
  1. Start OpenFaaS with Kubernetes
kubectl apply -f https://raw.githubusercontent.com/openfaas/faas-netes/master/namespaces.yml
kubectl apply -f https://raw.githubusercontent.com/openfaas/faas-netes/master/yaml/traefik/traefik.yaml
kubectl -n openfaas create secret generic basic-auth --from-literal=basic-auth-user=admin --from-literal=basic-auth-password=YOUR_PASSWORD_HERE
kubectl apply -f https://raw.githubusercontent.com/openfaas/faas-netes/master/yaml
  1. Get the OpenFaaS gateway URL and login credentials
export OPENFAAS_URL=http://127.0.0.1:31112
echo "Your OpenFaaS gateway URL: $OPENFAAS_URL"
echo -n "Enter OpenFaaS login password: "
read -s PASSWORD
echo ""
export OPENFAAS_PASSWORD=$PASSWORD
  1. Test OpenFaaS

To test OpenFaaS, you can deploy a sample function (called "figlet") using the following command:

faas-cli deploy -f https://raw.githubusercontent.com/openfaas/faas/master/sample-functions/figlet.yml

After deploying the function, you can invoke it by running the following command:

echo "openfaas" | faas-cli invoke figlet

This should output:

 _           _
| | ___  ___| |_
| |/ _ \/ __| __|
| | (_) \__ \ |_
|_|\___/|___/\__|

Congratulations! You have successfully installed OpenFaaS on Elementary OS Latest and tested a sample function.

Conclusion

In this tutorial, we have shown you how to install OpenFaaS on Elementary OS Latest using Kubernetes. You can now start exploring the platform and building your own serverless functions. Happy coding!
