Systems Advanced: DNS Server Lab

This repository contains the configuration files to set up a lab environment for practicing DNS Server with Docker containers.

The lab consists of one container and a compose file to set up the environment.

Setup Instructions

Pre-requisites

• Docker & Docker Compose
• Git

Clone the Repository

Clone this repository to your local machine:

git clone https://github.com/PXL-Systems-Advanced/dnslab.git

cd dnslab

Build and Run the Containers

Use Docker Compose to build the Docker image, create a bridge network (docker-dns_mynetwork), and start the container (dns_server).

docker compose up -d --build

Check the status of the containers:

docker ps

You should see the dns_server container running.

CONTAINER ID   IMAGE            COMMAND                  CREATED          STATUS          PORTS                                        NAMES
xxxxxxxxxxxx    docker-dns   "named -g -c /etc/bi…"   35 seconds ago   Up 34 seconds  0.0.0.0:8053->53/tcp, 0.0.0.0:8053->53/udp   dns_server

The bridge network should also be created:

docker network ls

xxxxxxxxxxxx   dnslab_mynetwork   bridge    local

Access the Container

docker exec -it dns_server sh

Stop and Remove the Containers

In the folder where the docker-compose.yml file is located, run:

docker compose down
