A small pandoc document processor (Markdown → PDF) with:

• Web UI on port 8085
• API on port 8086
• Health endpoint at /health
• Debian 12 slim base image
• PDF rendering via tectonic (a small, self-contained xetex-compatible engine — no texlive), pre-warmed at build time

The image source folder is still docker/media-processor/; the command, image and container are named doc-processor / vecnode-doc-processor.

Use the TUI action:

• vn app open doc-processor

This script builds the image, starts the container, waits for health, and opens the browser.

From repository root:

docker build -t vecnode-doc-processor:latest -f docker/media-processor/Dockerfile .
docker rm -f vecnode-doc-processor 2>/dev/null || true
docker run -d --rm --name vecnode-doc-processor \
	-p 8085:8085 \
	-p 8086:8086 \
	-e HOST_DESKTOP_DIR=/host/Desktop \
	-v "$HOME/Desktop:/host/Desktop" \
	vecnode-doc-processor:latest

On Windows PowerShell, use:

docker build -t vecnode-doc-processor:latest -f docker/media-processor/Dockerfile .
docker rm -f vecnode-doc-processor 2>$null
docker run -d --rm --name vecnode-doc-processor `
	-p 8085:8085 `
	-p 8086:8086 `
	-e HOST_DESKTOP_DIR=/host/Desktop `
	-v "${env:USERPROFILE}\Desktop:/host/Desktop" `
	vecnode-doc-processor:latest

• UI: http://localhost:8085
• API: http://localhost:8086
• Health: http://localhost:8086/health

• Drop Markdown files into the UI's path drop zone, then use Pandoc Processor → Markdown to PDF.
• Choose the LaTeX-style or Viewer-style profile plus font size, paper size, margin, TOC, etc.
• Generated PDFs are saved on the host Desktop (HOST_DESKTOP_DIR) in a pandoc-YYYY-MM-DD-HH-MM-SS folder.

docker logs -f vecnode-doc-processor
docker stop vecnode-doc-processor
docker ps --filter "name=vecnode-doc-processor"

• If Docker is not running, start Docker Desktop and retry.
• If ports are busy, free 8085/8086 (the launcher is native: vn app open doc-processor).
