2. Update your system to ensure all packages are up to date:

   apt update && apt upgrade -y

3. Install Docker by executing:

   apt install -y docker.io

4. Start Docker and enable it to run on boot:

   systemctl start docker
   systemctl enable docker

Installing Coolify

Now that Docker is set up, you can proceed to install Coolify.

Step 1: Pull the Coolify Docker Image

Use the following command to pull the latest Coolify image:

docker pull coollabsio/coolify

Step 2: Create a Docker Network

Coolify requires a dedicated network for its containers. Run:

docker network create coolify

Step 3: Create a Persistent Volume

To preserve your data and configurations:

docker volume create coolify_data

Step 4: Run Coolify

Now you can run Coolify with Docker. Execute:

docker run -d \
  --name coolify \
  --restart unless-stopped \
  -v coolify_data:/data \
  --network coolify \
  -p 8080:3000 \
  coollabsio/coolify

Accessing Coolify

After running the container, you can access Coolify via http://your_vps_ip:8080. Set up your admin account and start deploying your applications.
