anything-llm/aws/cloudformation/generate.mjs

// Note (tcarambat) This script should be executed from root via the `yarn generate::cloudformation` command only.
// This script will copy your current Docker .env settings being used into a slightly custom AWS CloudFormation template
// that you can upload and deploy on AWS in a single click!
// Recommended settings are already defined in the template but you can modify them as needed.
// AnythingLLM can run within the free tier services of AWS (t2.micro w/10GB of storage)
//
// This will deploy a fully public AnythingLLM so if you do not want anyone to access it please set the AUTH_TOKEN & JWT_SECRET envs
// before running this script. You can still run the collector scripts on AWS so no FTP or file uploads are required.
// Your documents and data do not leave your AWS instance when you host in the cloud this way.
