Run Streamlit Apps as serverless on AWS with HTTPS

This guide will walk you through the process of deploying a Streamlit web application on Amazon Web Services (AWS) using the AWS Cloud Development Kit (CDK) and protect the applicatoin URL with HTTPS. Streamlit is a popular Python library for creating web applications with minimal code, and CDK is an infrastructure as code (IaC) tool that simplifies the process of provisioning and managing AWS resources.

Prerequisites

Before you begin, make sure you have the following prerequisites:

AWS Account: You need an AWS account with the necessary permissions to create and manage resources.
AWS CLI: Install the AWS Command Line Interface and configure it with your AWS credentials.
Python and Pip: Ensure you have Python and Pip installed on your local machine.
CDK: Install CDK https://docs.aws.amazon.com/cdk/v2/guide/getting_started.html
Docker: Install Docker https://docs.docker.com/engine/install/

Deploy the sample application

Step 1: Create and activate a Virtualenv

In the root folder, run

python3 -m venv .venv
source .venc/bin/activate

Step 2: Install dependencies

pip install -r requirements.txt

Step 3: CDK synthesize a templare from your app

Make sure docker is running on your local machine. We will use it to build and bundle the Steamlit app docker image locally.

To synthesize a CDK app, use the cdk synth command. Let’s check out the template synthesized from the sample app.

Step 4: CDK bootstrapping

Bootstrapping is the process of provisioning resources for the AWS CDK before you can deploy AWS CDK apps into an AWS environment. (An AWS environment is a combination of an AWS account and Region).

Step 5: CDK deploy

Use cdk deploy to deploy a CDK app:

cdk deploy

Upon successful deployment, you will see the application's URL in the outputs:

Outputs:
