2. 🐳 Download Prebuilt Docker Image

If you prefer a quick setup, you can download the prebuilt Docker image from Docker Hub:

sudo docker image pull ilolm/docker-ctf

Then, run the Docker container with the following commands:

sudo docker container run -itd --rm --privileged --hostname docker-ctf --name docker-ctf -p 8080:8080 -p 22:22 -p 23:23 -p 3306:3306 ilolm/docker-ctf
sudo docker container exec -it docker-ctf docker compose -f /home/king/docker-web/docker-compose.yaml up -d

---

3. 🔧 Build the Docker Image manually

If you prefer to build the Docker image yourself, follow these steps:

1. Clone the repository:

   git clone https://github.com/ilolm/docker-CTF.git
   cd docker-CTF

2. Build the Docker image:

   sudo docker image build -t ctf:latest .

3. Run the Docker container:

   sudo docker container run -itd --rm --privileged --hostname docker-ctf --name docker-ctf -p 8080:8080 -p 22:22 -p 23:23 -p 3306:3306 ctf

4. Start the internal Docker Compose services:

   sudo docker container exec -it docker-ctf docker compose -f /home/king/docker-web/docker-compose.yaml up -d

4. 💻 VirtualBox Image

Alternatively, you can deploy the CTF using a VirtualBox image:

1. Download the VirtualBox image from the releases section.

2. Open VirtualBox, and either create a new VM or import the downloaded OVA file.

3. Set the network adapter to Bridged Adapter mode to ensure the VM can be accessed on the same network as your host machine.

4. Start the VM and note the assigned IP address.

5. Access the CTF challenge via the assigned IP address.
