Development Workflow

Setup

1. Build the development image:

   docker build -f Dockerfile.dev -t media_processing_dev .

   Or using docker-compose:

   docker-compose -f docker-compose.dev.yml build

Development Workflow

Option 1: Using Docker Compose (Recommended)

# Start the container
docker-compose -f docker-compose.dev.yml up -d

# Enter the container
docker exec -it media_processing_dev /bin/bash

# Inside the container, build your project
mkdir -p build && cd build
cmake -DCMAKE_PREFIX_PATH=/usr/local -DCMAKE_BUILD_TYPE=Debug ..
make -j$(nproc)

# Run your application
./processing_service_backup

# When done, stop the container
docker-compose -f docker-compose.dev.yml down

Option 2: Using Docker Run

# Run the container with volume mount
docker run -it --rm \
  --name media_processing_dev \
  -v "${PWD}:/app" \
  -p 5555:5555 \
  media_processing_dev

# Inside the container, build and run as above

Development Tips

1. Your source code is mounted - any changes you make on your host machine are immediately visible in the container
2. Rebuild when needed - after changing code, just run make in the /app/build directory
3. Generate Avro schemas - if you modify schemas:

   avrogencpp -i schemas/mediaProcessingSchema.avsc -o schemas/generated/MediaProcessingJob.hh -n xyz::virajdoshi::reelz

Production Build

When ready for production, use the optimized Dockerfile:

docker build -t media_processing .
docker run --name mediaProcessingService -it --rm -p 5555:5555 media_processing
