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
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.
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:
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

If you didn’t install kubectl and helm, you can install them in the following way:
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.
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.
You can start a Fluvio cluster by running fluvio cluster start.
$ fluvio cluster start

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
