Braintrust Terraform Module

This module is used to create the VPC, Databases, Lambdas, and associated resources for the self-hosted Braintrust data plane.

How to use this module

To use this module, copy the examples/braintrust-data-plane directory to a new Terraform directory in your own repository. Follow the instructions in the README.md file in that directory to configure the module for your environment.

If you're using a brand new AWS account for your Braintrust data plane you will need to run ./scripts/create-service-linked-roles.sh once to ensure IAM service-linked roles are created.

Useful scripts

dump-logs.sh

This script will dump the logs for the given deployment and services to the logs-<deployment_name> directory. This is useful for debugging issues with the data plane and sharing with the Braintrust team.

# ./dump-logs.sh <deployment_name> [--minutes N] [--service <svc1,svc2,...|all>]

./dump-logs.sh bt-sandbox
Fetching logs for the last 60 minutes for APIHandler...
Fetching logs for the last 60 minutes for brainstore...
✅ Saved logs for brainstore to logs-bt-sandbox/brainstore.log
✅ Saved logs for APIHandler to logs-bt-sandbox/APIHandler.log

create-service-linked-roles.sh

Required for new AWS accounts to ensure IAM service-linked roles are created.

./scripts/create-service-linked-roles.sh

Customized Deployments

It is highly recommended to use our root module to deploy Braintrust. It will make support and upgrades far easier. However, if you need to customize the deployment, you can pick and choose from our submodules since they are easily composable.

Look at our main.tf as a reference for how to configure the submodules. For example, if you wanted to re-use an existing VPC, you could remove the module.main_vpc block and pass in the existing VPC's ID, subnets, and security group IDs to the services, database, and redis modules.
