feat: add AI Bridge Proxy support to copilot module (#725)
## Description Add AI Bridge Proxy support to the copilot module. When enabled, the module configures proxy environment variables (`HTTPS_PROXY`, `NODE_EXTRA_CA_CERTS`) scoped to the copilot process tree (agentapi and copilot), routing Copilot traffic through AI Bridge Proxy without affecting other workspace traffic. GitHub authentication is still required, the proxy authenticates with AI Bridge using the Coder session token but does not replace GitHub authentication. Note: Uses [coder exp sync](https://coder.com/docs/admin/templates/startup-coordination) for startup coordination, ensuring the copilot module waits for the `aibridge-proxy` setup to complete before starting. ## Type of Change - [ ] New module - [ ] New template - [ ] Bug fix - [x] Feature/enhancement - [ ] Documentation - [ ] Other ## Module Information **Path:** `registry/coder-labs/modules/copilot` **New version:** `v0.4.0` **Breaking change:** [ ] Yes [x] No ## Testing & Validation - [x] Tests pass (`bun test`) - [x] Code formatted (`bun fmt`) - [x] Changes tested locally ## Related Issues Depends on: #721 Related to: https://github.com/coder/internal/issues/1187

### Usage with AI Bridge Proxy
|
||||
|
||||
[AI Bridge Proxy](https://coder.com/docs/ai-coder/ai-bridge/ai-bridge-proxy) routes Copilot traffic through [AI Bridge](https://coder.com/docs/ai-coder/ai-bridge) for centralized LLM management and governance.
|
||||
The proxy environment variables are scoped to the Copilot process only and do not affect other workspace traffic.
|
||||
|
||||
```tf
|
||||
module "aibridge-proxy" {
|
||||
source = "registry.coder.com/coder/aibridge-proxy/coder"
|
||||
version = "1.0.0"
|
||||
agent_id = coder_agent.main.id
|
||||
proxy_url = "https://aiproxy.example.com"
|
||||
}
|
||||
|
||||
module "copilot" {
|
||||
source = "registry.coder.com/coder-labs/copilot/coder"
|
||||
version = "0.4.0"
|
||||
agent_id = coder_agent.main.id
|
||||
workdir = "/home/coder/projects"
|
||||
enable_aibridge_proxy = true
|
||||
aibridge_proxy_auth_url = module.aibridge-proxy.proxy_auth_url
|
||||
aibridge_proxy_cert_path = module.aibridge-proxy.cert_path
|
||||
}
|
||||
```
|
||||
|
||||
> [!NOTE]
|
||||
> AI Bridge Proxy is a Premium Coder feature that requires [AI Governance Add-On](https://coder.com/docs/ai-coder/ai-governance).
|
||||
> See the [AI Bridge Proxy setup guide](https://coder.com/docs/ai-coder/ai-bridge/ai-bridge-proxy/setup) for details on configuring the proxy on your Coder deployment.
|
||||
> GitHub authentication is still required for Copilot as the proxy authenticates with AI Bridge using the Coder session token, but does not replace GitHub authentication.
|
||||
|
||||
> [!IMPORTANT]
|
||||
> When using AI Bridge Proxy, enable [startup coordination](https://coder.com/docs/admin/templates/startup-coordination) by setting `CODER_AGENT_SOCKET_SERVER_ENABLED=true` in the workspace container environment.
|
||||
> This ensures the Copilot module waits for the `aibridge-proxy` module to complete before starting. Without it, the Copilot start script may fail if the AI Bridge Proxy setup has not completed in time.
|

## Authentication
