Dash

Dash is an open-source web framework for Python that enables you to build interactive web applications, typically for data visualization, using Plotly. It’s particularly useful for creating complex dashboards with minimal coding effort.

Prepare Your Dash App

Make sure you have a Dash app ready and Dockerized. If not, you can use the official Docker image for Dash by Plotly. Here’s a simple example of a Dash app:

import dash
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash(__name__)

app.layout = html.Div(children=[
    html.H1(children='Hello Dash'),
    dcc.Graph(
        id='example-graph',
        figure={
            'data': [
                {'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'},
            ],
            'layout': {
                'title': 'Dash Data Visualization'
            }
        }
    )
])

if __name__ == '__main__':
    app.run_server(debug=True)

You can create a Dockerfile to containerize this app:

# Dockerfile
FROM python:3.8-slim

WORKDIR /app

COPY app.py /app/
RUN pip install dash

CMD ["python", "app.py"]

Build your Docker image locally:

docker build -t my-dash-app .

Create Your Akash Deployment YAML

To deploy to Akash, you need an SDL file. Here’s a sample deploy.yml:

version: "2.0"

services:
  web:
    image: my-dash-app:latest
    expose:
      - port: 8050
        as: 80
        to:
          - global: true

profiles:
  compute:
    web:
      resources:
        cpu:
          units: 0.1
        memory:
          size: 512Mi
        storage:
          size: 512Mi
  placement:
    westcoast:
      attributes:

      pricing:
        web:

          amount: 1000

deployment:

    westcoast:
      profile: web
      count: 1

Deploy to Akash

Before deploying your app on Akash, ensure you have the following prerequisites:

1. Akash Network Account: You should have an account on the Akash Network with sufficient AKT tokens to deploy the service.

2. Akash CLI or Console Access: Set up and configured on your machine.

Using Akash CLI

1. Deploy the App:

akash tx deployment create deploy.yml --from your-wallet --chain-id your-chain-id

2. Monitor Deployment:

akash query deployment list

3. Get Service URL: After deployment, you can find your service URL and access your Dash app.

Deploy Using Akash Console

1. Log in to Akash Console: Go to the Akash Dashboard and connect your wallet.

2. Create a New Deployment:

• Navigate to the “Deployments” section.

• Upload your deploy.yml file.

• Follow the instructions to complete the deployment.

3. Monitor: Check the status of your deployment through the console.

4. Access: Once the deployment is live, you can access your Dash app via the provided URL.
