Datauno Documentation

Hi! Welcome to Datauno Demo documentation. This v1 of the demo makes it possible to deploy Jitsu, Clickhouse, Hue and Metabase in Kubernetes with a single command. The configuration is designed to work with Linode Kubernetes Engine (LKE).

File Structure

datauno-demo folder consists of two sub-folders which are frontend and kubernetes.

frontend Folder

The frontend folder requires a standard web server which can serve static files. To easiest alternatives are:

1. Using Node.js run: npx sirv-cli --port 3000
2. Using Python run: python3 -m http.server --port 3000

Other than these two methods any static file serving web server should do the job. Examples are Nginx & Apache.

kubernetes Folder

All the required files and configuration that are required for deploying Jitsu, Clickhouse, Hue and Metabase in Kubernetes exist in this directory.

Tools Required

1. Latest version of Node.js (>=17.x.x)
2. Latest version of Kubernetes

Getting Started

After ensuring the above stated tools are installed on your local machine, this demo is designed to be executed/hosted on Linode Kubernetes Engine (LKE). Run this else where at your own risk.

Step 1 - Unzip the archive.

Run the below command to unzip the provided ZIP archive.

unzip datauno-demo.zip

Step 2 - Configuring kubectl command to connect with your cloud cluster.

Please follow the following instructions from Linode's documentation. To know how to apply this step. You can also follow the vendor specific steps if you're not intending to execute/deploy this demo onto Kubernetes.

Step 3 - Deploying the demo on LKE.

Enter into the unarchived folder by running 👇

cd datauno-demo

cd kubernetes

And then run the following command to create all the resources 👇

kubectl apply -k .

Active Services

To get a list of active or running services use the following command:

kubectl get services -n datauno-demo

The output gives a table with the following coloumns:

• Service Name
• Service Type
• Cluster-IP
• External-IP
• Port(s)
• Age

Pods

To get a list of active or running pods use the following command:

kubectl get pods -n datauno-demo

The output gives a table with the following coloumns:

• Pod Name
• Ready
• Status
• Restarts
• Age

Web Application

Step 1 - Starting the web application.

The web application is a static website, requiring a static file serving web server like Apache, Nginx or any custom designed server like Hapi.js, Express or even a simple Python command would do.

To start the web application, firstly enter into the frontend directory, by running the following command 👇

cd frontend

Now start the a server server in this directory. See top 👆 for some example commands.

Note: Hue and Metabase will open is a new tab because of the X-Frame-Options header. Read more about X-Frame-Options here.

Logs

To check the logs of a pod:

kubectl logs -n datauno-demo --follow <pod_name>

Delete Services

To delete all the pods and services:

kubectl delete -k .
