Docker Compose Production Setup

version: '3'

services:
  drawio:
    image: jgraph/drawio:latest
    container_name: drawio
    ports:
      - "8080:8080"
    restart: always
    environment:
      - DRAWIO_SELF_CONTAINED=1
      - DRAWIO_CONFIG={"defaultStorage":"device"}

  image-export:
    image: jgraph/drawio-export:latest
    container_name: drawio-export
    restart: always

Scaling & Configuration

• Storage Integration: For teams, configure Draw.io to use an internal S3 bucket or a private cloud storage instance via the DRAWIO_CONFIG environment variable.
• Custom Fonts: You can mount a directory of TTF/OTF fonts into the container to ensure brand consistency in diagrams.
• High Availability: Run the Draw.io container in a Kubernetes Deployment with multiple replicas to ensure zero downtime.

Security Best Practices

• Network Isolation: Ensure the instance is only accessible via a VPN or an authenticated reverse proxy.
• Regular Updates: Use the :latest tag carefully, but ensure you keep up with the frequent releases from the JGraph team.
• Audit Logging: Monitor the reverse proxy logs to track access patterns to the diagramming tool.
