This Streamlit application allows users to have a conversation with a virtual psychologist powered by the OpenAI ChatGPT model. The user can enter their message in the text input field and the ChatGPT model will generate a response. This project includes a Streamlit-based chatbot operationalized in AWS using AWS ECS Fargate.
This CloudFormation template creates a Virtual Private Cloud (VPC) with four subnets (two public and two private), an Internet Gateway, and a NAT Gateway. It also creates four route tables (one for each subnet) and routes for each route table to direct traffic to the Internet Gateway or NAT Gateway as appropriate.
The VPC has a CIDR block of 10.0.0.0/16, and the four subnets are created with CIDR blocks of 10.0.1.0/24, 10.0.2.0/24, 10.0.3.0/24, and 10.0.4.0/24. The public subnets are mapped to have public IP addresses on launch, and the private subnets are not.
There are also a few parameters defined at the beginning of the template that allow the user to specify an allowed IP address range for accessing port 80 on the load balancer, the name of an Elastic Container Registry (ECR) repository, and the path to an API key in the SSM Parameter Store.
To deploy the CloudFormation stack for this project, use the ./cf.yaml file. You can do this using the AWS Management Console, the AWS CLI, or the AWS SDKs.
| Parameter | Description | Default Value |
|---|---|---|
| AllowedIP | Comma-separated list of IP addresses that should be allowed to access port 80 on the load balancer | 0.0.0.0/0 |
| Repository | The name of the ECR repository | public.ecr.aws/a9t7y4w6/demo-chatgpt-streamlit:latest |
| ChatGptApiKeyPath | ChatGPT API Key path in SSM Parameter Store | /openai/api_key |
For example, to deploy the stack using the AWS CLI, you can use the following command with default values:
aws cloudformation create-stack \
--stack-name chatgpt-streamlit \
--template-body file://cf.yaml \
--capabilities CAPABILITY_IAMFor example, to deploy the stack using the AWS CLI, you can use the following command with custom values:
aws cloudformation create-stack --stack-name chatgpt-streamlit \
--template-body file://cf.yaml \
--parameters ParameterKey=AllowedIP,ParameterValue=1.2.3.4/32 ParameterKey=Repository,ParameterValue=public.ecr.aws/a9t7y4w6/demo-chatgpt-streamlit:latest ParameterKey=ChatGptApiKeyPath,ParameterValue=/openai/api_keyThis will create a new stack called chatgpt-streamlit using the cf.yaml template file and the CAPABILITY_IAM capability.
To build the Docker image for this project, use the Dockerfile in the ./app directory. You can do this using the docker build command.
For example, to build the image using the Dockerfile in the current directory, you can use the following command:
docker build -t chatgpt-streamlit .This will build the image and tag it with the name chatgpt-streamlit.
docker run -p 8501:8501 -e AWS_ACCESS_KEY_ID=$AWS_ACCESS_KEY_ID \
-e AWS_SECRET_ACCESS_KEY=$AWS_SECRET_ACCESS_KEY \
-e AWS_SESSION_TOKEN=$AWS_SESSION_TOKEN \
-e AWS_DEFAULT_REGION="us-east-1" \
public.ecr.aws/a9t7y4w6/demo-chatgpt-streamlit:latestThe Streamlit application is deployed in an AWS ECS cluster and is available through a web browser using the URL of the load balancer. To access the app, simply navigate to the URL in a web browser.
