coder-modules

Reusable Terraform modules for Coder workspace templates.

t3-server

modules/t3-server installs and starts the T3 Code headless server on a Coder agent. It creates an owner-only T3 Code app, listening on loopback port 3773 by default.

module "t3_server" {
  source = "./modules/t3-server"

  agent_id          = coder_agent.main.id
  working_directory = "/home/coder"
  initial_repositories = [
    {
      url       = "https://github.com/example/project.git"
      directory = "project"
    },
  ]
}

T3 is installed only when absent. Use channel (stable or nightly) to choose the first-install release train, or t3_version to pin an exact first install. The module leaves T3 state in $HOME/.t3, adds $HOME/.local/bin to the agent PATH, and records server logs at $HOME/.t3/logs/server.log.

Repositories supplied through initial_repositories are cloned once into $HOME/git/<directory> and registered as T3 projects before the server starts. Each URL must be HTTPS and each directory must be a simple filename.

ecr-credential-helper

modules/ecr-credential-helper installs the Amazon ECR Docker credential helper for a Coder user and configures named ECR account/region registries without replacing other Docker credentials.

module "ecr_credential_helper" {
  source   = "./modules/ecr-credential-helper"
  agent_id = coder_agent.main.id

  registries = [
    { account_id = "111122223333", region = "us-east-1" },
    { account_id = "444455556666", region = "us-west-2" },
  ]
}

The agent user needs AWS credentials with access to the configured ECR repositories when it runs Docker.
