ec2GraphNotebook

Description

This cdk project will provision a VPC, a Neptune cluster, an ALB, and an EC2 instance. The EC2 instance will have a UserData script to install JupyterHub, graph-notebook and other related components. The ALB will direct the user to Cognito for authentication before forwarding to EC2/JupyterHub.

Requirements

• CDK. This project uses the AWS CDK to deploy. To use the CDK:
  • Bootstrap the cdk with cdk bootstrap <accountnumber>/<region>
  • Create the dir 'ec2_graph_notebook' and cd into it
  • Initialize the app with cdk init app --language typescript
  • Copy 'ec_graph_notebook-stack.ts' to lib/ (overwriting the file that's there)
  • Copy the rest of the files to root directory (overwriting package.json)
  • Run npm install
• S3 bucket to house the authenticator and user-data.sh script
• Cognito User Pool
  • The User Pool will need an App Client configured with Authorization Code Grant and openid.
  • The App integration will require a domain name (ie: yourcooldomainprefix..auth.us-east-1.amazoncognito.com)
  • Once cdk deploy has run, you need to add the ALB URL to the Callback URL's field in the form of ${callbackUrl}/oauth2/idpresponse
• Certificate in ACM for the ALB

Issues

• Only supports Amazon Linux 2
• Requires an S3 bucket to host JupyterHub authenticator and user-data.sh script
• Requires an existing certificate in ACM
• Requires an existing Cognito User Pool
• EC2 Security Group needs to be tightened

Usage

1. Upload the below files to an S3 bucket:
   • jwtvalidation_authenticator-0.0.37-py3-none-any.whl
   • user-data.sh
2. Set the following environment variables:
   • S3BUCKETNAME // Thisis the bucket you uploaded the earlier files to
   • CERTIFICATEARN // This is the ARN of a certificate in ACM that can be attached to the ALB listener
   • JHUSERNAME // This is the username you want to use to login to JupyterHub and should exist in your Cognito User Pool
   • COGUSERPOOLARN // This is your Cognito User Pool ARN
   • COGUSERPOOLID // This is the Id of the App Client configured in Cognito
   • COGDOMAIN // This is the domain of the App Client configured in Cognito
3. Configure the user-data.sh script. There are three variables that need values.
4. Assume a session for your AWS account
5. Run cdk deploy
6. Update the Cognito User Pool callback URL with "https://${ALB_URL}/oauth2/idpresponse"
7. Get the ALB URL and use it to login into JupyterHub. This should spawn a graph notebook instance.
