Introduction

draw.io is a whiteboarding / diagramming software application. This project contains various docker implementations of draw.io and associated tools:

  • draw.io docker image that is always up-to-date with draw.io releases
  • draw.io export server image which allow exporting draw.io diagrams to pdf and images
  • docker-compose to run draw.io with the export server
  • docker-compose to run draw.io integrated within nextcloud
  • docker-compose to run draw.io self-contained without any dependency on diagrams.net website (with the export server, plantUml, Google Drive support, OneDrive support, and EMF conversion support (for VSDX export)

Description

The Dockerfile builds from tomcat:9-jre11 (see https://hub.docker.com/_/tomcat/)

Note: Starting from version 16.5.3, alpine and debian images are no longer maintained. We changed to a single image that uses the tomcat image with the least security vulnerabilities.

Forked from fjudith/draw.io

Features

  • Based on Tomcat so it can be used directly or behind a reverse-proxy
  • Self-Signed certificate autogen
  • Let's encrypt certificate autogen
  • Support SSL Keystore mount to /user/local/tomcat/.keystore

Quick Start

Run the container.

docker run -it --rm --name="draw" -p 8080:8080 -p 8443:8443 jgraph/drawio

Start a web browser session to http://localhost:8080/?offline=1&https=0 or https://localhost:8443/?offline=1

If you're running Docker Toolbox then start a web browser session to http://192.168.99.100:8080/?offline=1&https=0 or https://192.168.99.100:8443/?offline=1

?offline=1 is a security feature that disables support of cloud storage.

Environment variables

  • LETS_ENCRYPT_ENABLED: Enables Let's Encrypt certificate instead of self-signed; default false
  • PUBLIC_DNS: DNS domain to be used as certificate "CN" record; default draw.example.com
  • ORGANISATION_UNIT: Organisation unit to be used as certificate "OU" record; default Cloud Native Application
  • ORGANISATION: Organisation name to be used as certificate "O" record; default example inc
  • CITY: City name to be used as certificate "L" record; default Paris
  • STATE: State name to be used as certificate "ST" record; default Paris
  • COUNTRY_CODE: Country code to be used as certificate "C" record; default FR
  • KEYSTORE_PASS: ".keystore"/.jks" store password; default V3ry1nS3cur3P4ssw0rd
  • KEY_PASS: Private key password; default <ref:KEYSTORE_PASS>

HTTPS SSL Certificate via Let's Encrypt

Prerequisites:

  1. A Linux machine connected to the Internet with ports 443 and 80 open
  2. A domain/subdomain name pointing to this machine's IP address. (e.g., drawio.example.com)

Method:

  1. Create a directory to store the letsencrypt data. (e.g., /opt/docker/drawiodata/letsencrypt-log, /opt/docker/drawiodata/letsencrypt-etc, /opt/docker/drawiodata/letsencrypt-lib)
  2. Using jgraph/drawio docker image, run the following command
docker run -it -m1g -v "/opt/docker/drawiodata/letsencrypt-log:/var/log/letsencrypt/" -v "/opt/docker/drawiodata/letsencrypt-etc:/etc/letsencrypt/" -v "/opt/docker/drawiodata/letsencrypt-lib:/var/lib/letsencrypt" -e LETS_ENCRYPT_ENABLED=true -e PUBLIC_DNS=drawio.example.com --rm --name="draw" -p 80:80 -p 443:8443 jgraph/drawio

Notice that mapping port 80 to container's port 80 allows certbot to work in stand-alone mode. Mapping port 443 to container's port 8443 allows the container tomcat to serve https requests directly.

Changing draw.io configuration

Configuration is managed by DRAWIO_* environment variables. For a list of these variables, check the docker-entrypoint.sh file in the main directory. For example, these variables allow enabling integration with Google Drive, OneDrive, ...
