Installation Instructions

Before we dive into the installation process, let’s ensure we have the necessary prerequisites.

Prerequisites

• A system running a modern Linux distribution (Ubuntu, Debian, CentOS, etc.)
• Docker and Docker Compose installed
• Basic knowledge of the command line
• Stable internet connection

Step-by-Step Installation

1. Update Your System:

   sudo apt update && sudo apt upgrade -y

   Ensure your system is up-to-date to avoid any compatibility issues.

2. Install Docker:

   
   sudo apt install apt-transport-https ca-certificates curl software-properties-common -y
   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
   sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
   sudo apt update
   sudo apt install docker-ce -y
   sudo systemctl status docker
   

   Verify Docker is running correctly with the final command.

3. Install Docker Compose:

   
   sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   sudo chmod +x /usr/local/bin/docker-compose
   docker-compose --version
   

   Ensure Docker Compose is installed correctly by checking its version.

4. Create Docker Compose File for Docker-Webtop:

   Create a directory for Docker-Webtop and navigate into it:

   
   mkdir docker-webtop
   cd docker-webtop
   

   Create a docker-compose.yml file with the following content:

   
   version: "2.1"
   services:
   webtop:
   image: linuxserver/webtop
   container_name: webtop
   environment:
   PUID=1000
   PGID=1000
   TZ=Europe/London
   volumes:
   /path/to/data:/config
   ports:
   3000:3000
   restart: unless-stopped
   

   Replace /path/to/data with your desired configuration directory and Europe/London with your timezone.

5. Start Docker-Webtop Service:

   docker-compose up -d

   The -d flag runs the service in detached mode.

6. Access Docker-Webtop:

   Open your web browser and navigate to http://:3000. You should see the Docker-Webtop login screen.
