# tinqs/ci orchestrator

Lambda-based CI dispatcher for Tinqs Studio. Receives Gitea webhooks and routes jobs to the right execution environment.

## Architecture

```
Gitea push webhook
       │
       ▼
  API Gateway POST /webhook
       │
       ▼
  ci-dispatch Lambda
       │
       ├── runs-on: go/node/docker/godot
       │     → Start Fargate task with matching image
       │     → Track in DynamoDB for cancel
       │
       ├── runs-on: deploy
       │     → Invoke ci-exec Lambda directly
       │
       └── runs-on: host
             → Skip (handled by registered runner)
```

## Deploy

Requires: AWS SAM CLI, AWS credentials, Gitea token.

```bash
# First time (interactive)
GITEA_TOKEN=xxx make deploy-guided

# Subsequent deploys
GITEA_TOKEN=xxx SUBNETS=subnet-abc,subnet-def SECURITY_GROUP=sg-xxx make deploy
```

After deploy, configure the webhook URL as a Gitea **system webhook**:
- URL: `https://<api-id>.execute-api.eu-west-1.amazonaws.com/prod/webhook`
- Method: POST
- Content type: application/json
- Events: Push, Workflow Job (for cancel)

## Cancel support

When a user cancels a job in the Gitea UI, the `workflow_job` webhook fires with `action: cancelled`. The dispatcher looks up the Fargate task ARN in DynamoDB and calls `ecs:StopTask`.

A cleanup cron (every 5 min) also kills Fargate tasks that have been running longer than 30 minutes.

## Local testing

```bash
make build
make test-local  # requires SAM CLI + Docker
```
