Ubuntu VNC Desktop

A minimal, stable Ubuntu desktop environment optimized and accessible directly in your browser.

Based On

This image is based on vemonet/docker-ubuntu-vnc-desktop with modifications for being a more minimal base image.

Changes from Original

Removed:

• Chrome/Chromium browser
• FFmpeg and media processing tools
• Media players (VLC, etc.)
• ARM architecture support
• Web development tools
• Unnecessary desktop applications

Kept:

• Ubuntu 22.04 LTS base
• LXDE lightweight desktop environment
• x11vnc + noVNC for browser-based access
• Supervisor for process management
• Basic CLI tools
• Terminal emulator

Added Dependencies: Included python3-websockify to ensure the web-to-VNC connection works without needing git.

Deploy on DSRI OpenShift

Use the template in the dsri-documentation repository.

Local Testing

# Build the image
docker build -t ubuntu-vnc:tag .

# Run locally
docker run -d -p 6080:80 -e PASSWORD=test --name ubuntu-desktop ubuntu-vnc:tag

# Access in browser: http://localhost:6080

# Cleanup
docker stop ubuntu-desktop  && docker rm ubuntu-desktop 

Persistent Storage

When deployed on DSRI, use the /root/persistent directory for files that should survive pod restarts.

# Example: Install software to persistent location
mkdir -p /root/persistent/bin

# Add to PATH
echo 'export PATH=/root/persistent/bin:$PATH' >> ~/.bashrc
