# 1. Create a non-root user (Hugging Face strictly requires user ID 1000)
RUN useradd -m -u 1000 user
ENV HOME=/home/user
ENV PATH=/home/user/.local/bin:$PATH

# 2. Install desktop, VNC, and web access
RUN apt-get update && apt-get install -y \

    x11vnc xvfb \
    novnc websockify \

# 3. Bulletproof Health Check Fix
# We create a custom index.html that gives Hugging Face a "200 OK" health status, 
# while instantly redirecting your browser to the actual VNC page.
RUN echo '<meta http-equiv="refresh" content="0; url=vnc.html">' > /usr/share/novnc/index.html

WORKDIR $HOME

# 4. Set VNC password and fix permissions for the user
RUN mkdir -p $HOME/.vnc && \
    x11vnc -storepasswd 1234 $HOME/.vnc/passwd && \
    chown -R user:user $HOME

# 5. Switch to the Hugging Face required user
USER user

# 6. Expose web port
EXPOSE 7860

# 7. Start everything (Removed the failing DPMS command)
