| # Dockerfile for Hugging Face Spaces deployment | |
| # Base: DeepISLES image with nnU-Net, SEALS, and all ML dependencies | |
| # See: docs/specs/07-hf-spaces-deployment.md | |
| # | |
| # IMPORTANT: During Docker build, GPU is NOT available. | |
| # All GPU operations happen at runtime only. | |
| # | |
| # CRITICAL: DeepISLES code lives at /app/src/ in the base image. | |
| # We install our demo at /home/user/demo to avoid overwriting DeepISLES. | |
| # NOTE: isleschallenge/deepisles only publishes 'latest' tag on Docker Hub. | |
| # For reproducibility, consider using a SHA digest if available: | |
| # FROM isleschallenge/deepisles@sha256:<digest> | |
| # Check https://hub.docker.com/r/isleschallenge/deepisles/tags for updates. | |
| # Current base: DeepISLES v1.1 (as of Dec 2025) | |
