Linux Installation

 

Install Fluvio CLI

The Fluvio CLI (command-line interface) is an all-in-one tool for setting up, interacting, and managing with Fluvio clusters.

Install the Fluvio CLI by running the following command:

curl -fsS https://packages.fluvio.io/v1/install.sh | bash
 

Setting up a Fluvio cluster on Kubernetes

With CLI, you can create and manage fluvio clusters on Kubernetes. Before you can create a Fluvio cluster, you need to have a Kubernetes cluster up and running.

 

Installing Kubernetes cluster

Either you can create a cluster on your local machine or you can deploy it to a cloud provider.

For installing on your local machine, here are suggested Kubernetes installation options:

  1. K3d
  2. Kind
  3. Minikube

After installing Kubernetes, you can run the following command to check if your Kubernetes cluster is up and running:

$ kubectl config current-context
minikube

Some of Kubernetes installation will install kubectl and helm. You can check it by:

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.3", GitCommit:"ca643a4d1f7bfe34773c74f79527be4afd95bf39", GitTreeState:"clean", BuildDate:"2021-07-15T21:04:39Z", GoVersion:"go1.16.6", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.2", GitCommit:"092fbfbf53427de67cac1e9fa54aaa09a28371d7", GitTreeState:"clean", BuildDate:"2021-06-16T12:53:14Z", GoVersion:"go1.16.5", Compiler:"gc", Platform:"linux/amd64"}
$ helm version
version.BuildInfo{Version:"v3.6.2", GitCommit:"ee407bdf364942bcb8e8c665f82e15aa28009b71", GitTreeState:"clean", GoVersion:"go1.16.5"}

If you didn’t install kubectl and helm, you can install them in the following way:

 

Install Kubectl

kubectl is the Kubernetes command-line tool. It is used to run commands against Kubernetes clusters.

Follow the instructions at the kubectl installation page and follow the instructions to download and install kubectl on Linux.

 

Install Helm

Helm is the package manager for Kubernetes.

Follow the instructions at the helm installation page and follow the instructions to download and install helm on Linux.

$ fluvio cluster start

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 topic.

$ 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
Consuming records from the beginning of topic 'greetings'
Hello, Fluvio

Way to go! You’re well on your way to writing real-time distributed apps with Fluvio!
