# CRITICAL: The storage directory must exist as an empty directory in the image
# This allows Docker to mount Named Volumes to subdirectories (storage/cache, storage/logs, etc.)
# without needing to create the parent directory at runtime (which fails due to read-only overlay)

# Create appuser but DON'T switch yet - let entrypoint handle volumes first
RUN groupadd -g 1000 appuser && useradd -u 1000 -g appuser -m appuser

RUN apt-get update && apt-get install -y gosu && apt-get clean && rm -rf /var/lib/apt/lists/*

# Note: USER switch happens in entrypoint AFTER volumes are mounted
