+ +## **Environment Variables for Model Loading** + +### **Emotion Detection Model Sources** +The consolidated Dockerfile supports multiple sources for loading the emotion detection model: + +```bash +# Hugging Face Hub model (default: "0xmnrv/samo") +EMOTION_MODEL_ID=your-model-id + +# Hugging Face authentication token (if model is private) +HF_TOKEN=your-hf-token + +# Local model directory (if you have a local copy) +EMOTION_MODEL_LOCAL_DIR=/path/to/local/model + +# Archive URL for model download (tar.gz/zip) +EMOTION_MODEL_ARCHIVE_URL=https://example.com/model.tar.gz + +# Remote inference endpoint +EMOTION_MODEL_ENDPOINT_URL=https://your-endpoint.com/predict +``` + +### **Priority Order for Model Loading:** +1. **Local directory** (if `EMOTION_MODEL_LOCAL_DIR` is set and exists) +2. **HF Hub direct** (using `EMOTION_MODEL_ID`) +3. **HF snapshot download** (cached to `HF_HOME`) +4. **Archive download** (from `EMOTION_MODEL_ARCHIVE_URL`) +5. **Remote endpoint** (using `EMOTION_MODEL_ENDPOINT_URL`) +6. **Fallback to local BERT** (if all above fail) + +### **Example Environment Configuration:** +```bash +# For production with HF Hub model +export EMOTION_MODEL_ID="0xmnrv/samo" +export HF_TOKEN="hf_your_token_here" + +# For local development +export EMOTION_MODEL_LOCAL_DIR="./models/emotion-detection" + +# For archive-based deployment +export EMOTION_MODEL_ARCHIVE_URL="https://your-cdn.com/models/emotion-v1.0.tar.gz" +``` + +**Note:** If no environment variables are set, the system will attempt to load from HF Hub and gracefully fall back to local BERT if that fails. This fallback behavior is normal and expected in many deployment scenarios. + +## **Requirements File Mapping** + +The Dockerfile automatically selects the appropriate requirements file: +- `BUILD_TYPE=minimal` โ†’ `requirements_minimal.txt` +- `BUILD_TYPE=unified` โ†’ `requirements_unified.txt` +- `BUILD_TYPE=secure` โ†’ `requirements_secure.txt` +- `BUILD_TYPE=production` โ†’ `requirements_production.txt` + +## **Testing the Builds** + +### **Test Minimal Version** +```bash +docker run --rm -p 8080:8080 samo-dl-minimal +curl http://localhost:8080/health +``` + +### **Test Unified Version** +```bash +docker run --rm -p 8080:8080 samo-dl-unified +curl http://localhost:8080/health +# Should show ML models as available +``` + +### **Test Secure Version** +```bash +docker run --rm -p 8080:8080 samo-dl-secure +curl http://localhost:8080/health +``` + +## **Migration from Old Dockerfiles** + +### **Before (Multiple Files)** +```bash +# Had to remember which Dockerfile to use +docker build -f deployment/cloud-run/Dockerfile -t samo-dl . +docker build -f deployment/cloud-run/Dockerfile.unified -t samo-dl-unified . +docker build -f deployment/cloud-run/Dockerfile.minimal -t samo-dl-minimal . +docker build -f deployment/cloud-run/Dockerfile.secure -t samo-dl-secure . +``` + +### **After (Single File)** +```bash +# One Dockerfile, multiple variants +docker build --build-arg BUILD_TYPE=minimal -f deployment/cloud-run/Dockerfile.consolidated -t samo-dl-minimal . +docker build --build-arg BUILD_TYPE=unified --build-arg INCLUDE_ML=true -f deployment/cloud-run/Dockerfile.consolidated -t samo-dl-unified . +docker build --build-arg BUILD_TYPE=secure --build-arg INCLUDE_SECURITY=true -f deployment/cloud-run/Dockerfile.consolidated -t samo-dl-secure . +``` + +## **Benefits** + +โœ… **Single source of truth** - one Dockerfile to maintain +โœ… **Consistent behavior** - same base image, same patterns +โœ… **Easy to update** - change once, affects all variants +โœ… **Clear documentation** - obvious what each build arg does +โœ… **Reduced duplication** - no repeated code +โœ… **Flexible builds** - mix and match features as needed + +## **Next Steps** + +1. **Test all build variants** to ensure they work correctly +2. **Update CI/CD pipelines** to use the new consolidated approach +3. **Remove old Dockerfiles** once migration is complete +4. **Update deployment scripts** to use build arguments diff --git a/deployment/cloud-run/debug_api_import.py b/deployment/cloud-run/debug_api_import.py index 31cee7bdb..9ceee410d 100644 --- a/deployment/cloud-run/debug_api_import.py +++ b/deployment/cloud-run/debug_api_import.py @@ -94,4 +94,4 @@ def test_handler(error): except Exception as e: print(f"โŒ model_utils import failed: {e}") -print("\n๐Ÿ” Debug complete.
