Want a Cloud Desktop to access it from anywhere? Spin it up in 11 Steps from your pc/laptop.

Aungkon Malakar — Sat, 06 Dec 2025 07:17:33 +0000

1. Create an Admin User

sudo useradd -m -s /bin/bash -G sudo admin
sudo passwd admin

admin will be the user for GUI and VNC sessions.
The sudo group allows administrative commands.

2. Install Required Packages

sudo apt update
sudo apt install -y curl lubuntu-desktop tigervnc-standalone-server tigervnc-common nano openssh-server wget gnupg

lubuntu-desktop provides the LXQt desktop environment. for i3wm use i3 or for xfce install xfce4 xfce4-goodies
TigerVNC provides the VNC server.
OpenSSH allows remote terminal access.
wget/curl/gnupg are required for Chrome and Tailscale installations.

3. Enable and Start SSH

sudo systemctl enable ssh
sudo systemctl start ssh

Ensures SSH starts automatically on boot.

4. Install Google Chrome (Optional)

cd /tmp
wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
sudo apt install -y ./google-chrome-stable_current_amd64.deb

Provides a modern browser for GUI applications.

5. Install Tailscale (Optional VPN)

curl -fsSL https://tailscale.com/install.sh | sh
tailscale up

Tailscale enables secure remote access to the container.

6. Configure VNC for Admin (do as admin user)

su - admin
mkdir -p /home/admin/.vnc
echo -e "#!/bin/bash\nstartlxqt" | sudo tee /home/admin/.vnc/xstartup # use i3 or startxfce4 depends on your appropiate DE or WM instead of startlxqt
sudo chmod 777 /home/admin/.vnc/xstartup
sudo -u admin vncpasswd
exit

xstartup launches LXQt when VNC connects.
Permissions 777 ensure security.
vncpasswd sets a VNC password for the admin user.

7. Create Systemd Service for TigerVNC

cat <<EOF | sudo tee /etc/systemd/system/vncserver@.service
[Unit]
Description=Start TigerVNC server for user %i
After=network.target

[Service]
Type=forking
User=%i
ExecStart=/usr/bin/vncserver :1 -geometry 1920x1080 -depth 24
ExecStop=/usr/bin/vncserver -kill :1
Restart=on-failure
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable vncserver@admin.service
sudo systemctl start vncserver@admin.service

Starts VNC automatically at boot for the admin user.
Default resolution: 1920x1080.

8. Install noVNC

sudo git clone https://github.com/novnc/noVNC.git /opt/noVNC
sudo git clone https://github.com/novnc/websockify /opt/noVNC/utils/websockify

noVNC provides browser-based access to the VNC session.

9. Generate SSL Certificate for noVNC

sudo mkdir -p /opt/noVNC/certs
sudo openssl req -x509 -newkey rsa:4096 -keyout /opt/noVNC/certs/key.pem -out /opt/noVNC/certs/cert.pem -days 365 -nodes \
  -subj "/CN=localhost"

Secures the noVNC connection over HTTPS.
Certificate valid for 1 year.

10. Create Systemd Service for noVNC

cat <<EOF | sudo tee /etc/systemd/system/novnc.service
[Unit]
Description=noVNC Service
After=network.target

[Service]
Type=simple
ExecStart=/opt/noVNC/utils/novnc_proxy --vnc localhost:5901 --cert /opt/noVNC/certs/cert.pem --key /opt/noVNC/certs/key.pem --listen 443
Restart=on-failure
User=root

[Install]
WantedBy=multi-user.target
EOF

sudo systemctl daemon-reload
sudo systemctl enable novnc.service
sudo systemctl start novnc.service

Allows accessing the LXQt desktop via HTTPS in a web browser.
Default noVNC port: 443.

11. Access Instructions

Browser (noVNC): https://<container-ip-or-hostname>/

Authorization — Control who can do what.
Rate Limiting — Prevent abuse and protect resources.
API Versioning — Manage changes and maintain stability.
Whitelisting — Allow only trusted IPs or domains.
Check OWASP API Security Risks — Stay informed of vulnerabilities.
Use an API Gateway — Add a layer of governance and control.
Error Handling — Don’t expose sensitive details.
Input Validation — Always sanitize and validate

Securing your APIs isn’t optional — it’s foundational. #APISecurity #DevOps #CyberSecurity #BackendDevelopment #SecureAPIs Which of these are you implementing already? Let’s discuss! 🔐
