Installing Fluvio Locally

Fluvio is built to run on Kubernetes, an open-source system that automates the deployment of containerized apps. If you haven’t heard of Kubernetes or containers, just think of them as tools that help run applications on many computers at once. To get started with Fluvio locally, we’ll need to install a version of Kubernetes called Minikube which is meant for testing out Kubernetes apps locally.


Before getting started, make sure you have the Fluvio CLI installed, as we’ll be using that to interact with your cluster and make sure everything is working as expected.

Required Packages 

  1. Install Docker
  2. Install Minikube
  3. Install Kubectl
  4. Install Helm

If you already have docker, kubectl, helm, and minikube set up, feel free to scroll down to the installing fluvio section.

Installing Docker 

Docker is a container engine that Minikube can use to run Kubernetes apps. Go to the Docker downloads page and choose the edition built for your OS. Follow all of the installation steps, then verify that you’re able to run docker without using sudo:

$ docker run hello-world

Installing Minikube 

Head on over to the Minikube installation page and follow the instructions to download and install minikube. Make sure it is installed correctly by checking the version:

$ minikube version
minikube version: v1.17.1
commit: 043bdca07e54ab6e4fc0457e3064048f34133d7e

To start your minikube cluster, run the following. This will vary depending on what OS you use, so make sure you are following the instructions for your platform.

In your Mac terminal:

minikube start --driver=hyperkit --kubernetes-version=1.19.6

In your Linux terminal:

minikube start --driver=docker --kubernetes-version=1.19.6

Installing Kubectl 

Minikube is nothing more than just a mini Kubernetes. That means that we need to get the Kubernetes tool kubectl in order to configure and interact with our mini cluster just like you would with a regular cluster. Head on over to the installing kubectl page to get that installed. Once you’re done, you should be able to run the following command to check that it’s installed correctly.

$ kubectl version --short
Client Version: v1.20.1
Server Version: v1.19.6

Installing Helm 

Helm is a package manager that makes it easy to install apps for Kubernetes. Fluvio is packaged as a “Helm chart” (the name for a package in Helm), and the Fluvio CLI can install that chart for you by calling the helm executable with all the right options. In order to do this, you need to have helm installed.

You can install helm from the helm releases page. Once it’s installed, make sure it works by printing the version.

$ helm version --short

Installing Fluvio 

Now that we’ve got all of our tools installed, let’s actually get Fluvio up and running! If you run into any problems along the way, make sure to check out our troubleshooting page to find a fix.

First, we have to open up a “minikube tunnel”, which allows programs on our local machine to connect to programs running in minikube. This is how Fluvio commands communicate with the local Fluvio cluster in minikube. To do this, we need to run the following command:

$ sudo true && (sudo nohup minikube tunnel >/tmp/tunnel.out 2>/tmp/tunnel.out &)

Once we have the minikube tunnel running, we can run the startup command.

$ fluvio cluster start
✅ ok: Kubernetes config is loadable
✅ ok: Supported helm version is installed
✅ ok: Load balancer is up
✅ ok: Fluvio system charts are installed
✅ ok: Previous fluvio installation not found
Waiting up to 60 seconds for Fluvio cluster version check...
Successfully installed Fluvio!

You can check that everything worked by listing out the cluster’s SPUs:

$ fluvio cluster spu list
  0  main-0  Online  "managed"   -  fluvio-spg-main-0.fluvio-spg-main:9006

Hello, Fluvio! 

Congratulations, you’ve successfully installed Fluvio on your local machine! Let’s use the Fluvio CLI to play with some basic functionality.

The first thing we need to do is create a Fluvio topic. A Topic is like a category where related events live together. We can create a new topic with the following command:

$ fluvio topic create greetings
topic "greetings" created

Now that we have a topic, we can produce some messages! Use the following command to send a message to the greetings topic:

$ echo "Hello, Fluvio" | fluvio produce greetings

Finally, we can consume messages back from the topic

$ fluvio consume greetings -B -d
Hello, Fluvio

Way to go! You’re well on your way to writing real-time distributed apps with Fluvio! Next, check out our Tutorials page to see real-world examples of Fluvio in action.
