Terraform module for Sourcegraph executors (AWS)

This repository provides a Terraform module to provision Sourcegraph executor compute resources on AWS. If you are installing executors for the first time, follow our complete setup guide.

This repository provides four submodules:

1. The executors module provisions compute resources for executors.
2. The docker-mirror module provisions a Docker registry pull-through cache.
3. The networking module provisions a network to be shared by the executor and Docker registry resources.
4. The credentials module provisions credentials required by the Sourcegraph instance to enable observability and auto-scaling of executors.

The multiple-executors example uses the submodule directly to provision multiple executor resource groups performing different types of work. Follow this example if you are:

1. Provisioning executors for use with multiple features (e.g., both auto-indexing and server-side batch changes), or
2. Provisioning resources for multiple Sourcegraph instances (e.g., test, prod)

This repository also provides a root module combining the executors, network, and docker-mirror resources into an easier to use package.

The single-executor example uses the root module to provision a single executor type. Follow this example if you are deploying to a single Sourcegraph instance and using a single executors-backed feature.
