2 min readFeb 23, 2019

To share a Dash app, you need to “deploy” your Dash app to a server. The guide below works for Dash application with and without Dash DAQ components. We’ll deploy app on AWS in easiest way.

Dash “Hello, World!”

Let’s create new directory (e.g., medium). Create new application.py file with code below:

Note: Line app.scripts.config.serve_locally = True is required for Dash DAQ components.

Python dependencies

Navigate to project directory (e.g., medium)and create new requirements.txt file with code below:

AWS Elastic Beanstalk

AWS Elastic Beanstalk is an easy-to-use service for deploying and scaling web applications and services developed with Python.

Install the Elastic Beanstalk Command Line Interface (EB CLI):

$ sudo pip install awsebcli

If you want install EB CLI on Amazon Linux, use instruction below:

$ sudo yum update$ sudo yum install git
$ sudo yum groupinstall "Development Tools"
$ sudo yum install libffi-devel openssl-devel$ git clone https://github.com/aws/aws-elastic-beanstalk-cli-setup.git
$ ./aws-elastic-beanstalk-cli-setup/scripts/bundled_installer$ echo 'export PATH="/home/ec2-user/.ebcli-virtual-env/executables:$PATH"' >> ~/.bash_profile && source ~/.bash_profile$ rm -rf aws-elastic-beanstalk-cli-setup

Initiate EB

Navigate to project directory (e.g., medium) and initialize your directory with the EB CLI:

$ eb init

Select a default region (e.g., eu-west-1). Enter application name (e.g., medium).

It appears you are using Python. Is this correct?
(Y/n):

Enter Y.

Select Python version (e.g., Python 3.6).

Do you want to set up SSH for your instances?
(Y/n):

Enter n.

Deploy Dash app

Create a new environment:

$ eb create

Enter environment name (e.g., medium-dev). Enter DNS CNAME prefix (e.g., medium-dev). Select a load balancer type (e.g., application).

Open the application URL in a browser:

$ eb open

Update Dash app

Let’s update Dash app. Change:

html.H1('Hello, World!')

line to:

html.H1('Hello, Medium!')

Deploy new source code to the environment:

$ eb deploy
