Automate deploying Lemmy to AWS using CDK

Lemmy AWS CDK

Lemmy is a Reddit-style federated social network that speaks ActivityPub. It is written in Rust.

This contains the necessary infrastructure definitions to deploy Lemmy to AWS using their Cloud Development Kit.

Included:

• ECS fargate cluster
  • Lemmy-UI
  • Lemmy
  • Pictrs
  • IFramely
• CloudFront CDN
• EFS storage for image uploads
• Aurora Serverless Postgres DB
• Bastion VPC host
• Load balancers for Lemmy and IFramely
• DNS records for your site

Quickstart

Clone Lemmy and Lemmy-UI to the directory above this.

cp example.env.local .env.local
# edit .env.local

You should edit .env.local with your site settings.

npm install -g aws-cdk
npm install
cdk bootstrap
cdk deploy

Cost

This is not the cheapest way to run Lemmy. The Serverless Aurora DB can run you ~$90/mo if it doesn't go to sleep.

Useful CDK commands

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth emits the synthesized CloudFormation template
