# Docker Compose for testing remote transcoding workers
#
# Prerequisites:
# 1. Worker API running on host: ./start-worker-api.sh (or uvicorn api.worker_api:app --port 9002)
# 2. Register a worker: curl -X POST http://localhost:9002/api/worker/register
# 3. Set the VLOG_WORKER_API_KEY environment variable with the returned key
#
# Usage:
#   export VLOG_WORKER_API_KEY=<your-api-key>
#   docker compose -f docker-compose.worker.yaml up --build
#
#   # Scale workers:
#   docker compose -f docker-compose.worker.yaml up --build --scale vlog-worker=3
