Prerequisites

Before installing Dockge, ensure you have:

• A VPS with at least 1 CPU core, 2 GB RAM.
• A clean Linux distribution, preferably Ubuntu 22.04 LTS.
• SSH access with root or sudo privileges.
• Basic knowledge of Linux command line.

Step 1: Set Up Your VPS

1. Connect via SSH:

ssh root@your-vps-ip

2. Update the system:

apt update && apt upgrade -y

3. Install Docker and Docker Compose:

apt install -y docker.io docker-compose
systemctl enable --now docker

Ensure Docker is running:

docker --version
docker-compose --version

Step 2: Install Dockge

1. Create a directory for Dockge:

mkdir -p /opt/dockge
cd /opt/dockge

2. Download the latest Docker Compose file:

Create a docker-compose.yml:

version: '3'

services:
  dockge:
    image: ghcr.io/dockge/dockge:latest
    container_name: dockge
    restart: always
    ports:
      - "8080:8080"
    volumes:
      - ./data:/app/data
      - /var/run/docker.sock:/var/run/docker.sock

Save this as docker-compose.yml.

3. Start the container:

docker-compose up -d

Dockge should now be running on port 8080.

Step 3: Configure Firewall and Domain

• Open port 8080 (or your preferred port):

ufw allow 8080/tcp

• Optionally, set up a reverse proxy with Nginx for SSL and custom domains:

server {
    listen 80;
    server_name dockge.yourdomain.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

• Reload Nginx:

systemctl reload nginx

• For HTTPS, utilize Certbot to acquire SSL certificates.

Step 4: Access and Use Dockge

Navigate to your VPS IP or domain:

http://your-vps-ip:8080

or if using a domain with SSL:

https://dockge.yourdomain.com

Log in, and you’ll find an intuitive interface to deploy, manage, and monitor Docker containers.

Optimization Tips

• Persistent Data: Store Docker data on a dedicated volume or external storage.
• Security: Regularly update your VPS and Docker images.
• Backups: Automate backups for your Dockge data directory.
• Monitoring: Use tools like Glances or Portainer for enhanced visibility.

FAQs

1. Is it safe to run Dockge on a VPS?

Running Dockge on a VPS is safe provided you follow good security practices. Keep your server updated, use firewalls to restrict unauthorized access, and set up SSL encryption. Regularly update Dockge and Docker images to patch vulnerabilities. For additional security, consider SSH key authentication and fail2ban.

2. How resource-intensive is hosting Dockge?

Dockge’s resource usage depends on the number and size of containers managed. A small VPS with 2 GB RAM and 1 CPU core is sufficient for basic setups. As your container count grows or workloads become intensive, upgrading your VPS may be necessary to maintain performance.

3. Can I run multiple instances of Dockge?

Yes, you can run multiple Dockge instances in isolated containers or virtual machines, but it’s generally simpler and more efficient to run a single instance and manage your containers within it. For large-scale or segmented environments, consider orchestrating Docker Swarm or Kubernetes with multiple nodes.
