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.
Before you begin, make sure you have the following prerequisites in place:
git clone https://github.com/openfaas/faas.git
cd faas
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
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
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.
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!
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
