Consolidate apt commands, use shallow git clone, and prevent cache files
from being stored in the image. These changes reduce the final image
size from 12.9GB to 10.1GB (21.7% reduction).
The optimizations include:
- Replace apt with apt-get following container best practices
- Merge multiple apt commands into a single instruction to reduce layers
- Clean up apt cache with `rm -rf /var/lib/apt/lists/*` to reduce size
- Use `--no-cache-dir` flag with pip to prevent caching
- Use shallow `git clone` with `--depth 1` for faster downloads
- Also apply git shallow submodule initialization with `--depth=1`
Image size reduced by 2.8GB, based on `docker images` output:
REPOSITORY TAG IMAGE ID CREATED SIZE
rwkv-runner after b9f5f7cba3dd 36 minutes ago 10.1GB
rwkv-runner before 4fc66df1e9b8 50 minutes ago 12.9GB
These changes follow Docker best practices by reducing layer count,
removing unnecessary files that would otherwise be stored in the image,
and improving CI efficiency, storage usage, and deployment speed in
production environments.
