This repository provides a Dockerized BIND9 setup for local DNS resolution, which can be particularly useful for developers looking to simulate production DNS environments locally or for internal network purposes.

Dockerized setup for easy deployment.Pre-configured BIND9 for dusha-project.local.

dusha-project.local. is a sample domain which I'm using. The goal is to configure dns in suchway that when you enteringhttp://dusha-project.local in browser - it should point tothe localhost 80 port. And instead of using /etc/hosts like:

127.0.0.1 dusha-project.local

I want to achieve same results using bind9 dockerized.

• Docker
• Docker Compose

1. Clone the repository:

git clone https://github.com/sukhoy94/dns-bind9.git

2. Navigate to the repository folder:

cd dns-bind9

3. Build and Start the Docker container:

docker-compose up -d

4. Test the DNS resolution:

dig @your_container_ip dusha-project.local

Configuration files for BIND9 are located in the bind9-config directory. You can modify these files as per your requirements:

• named.conf.local - Defines the zones.
• db.local.template - Contains the DNS records for the defined zone.

To configure your system to use this DNS server, you'll need to add theDNS server's IP to the /etc/resolv.conf file on your host.

1. Open the /etc/resolv.conf file in an editor:

sudo nano /etc/resolv.conf

2. Add the IP of your Docker container at the top of the list of DNS servers:

nameserver your_container_ip

3. Save and close the file.

Now, any DNS query made from your system will first be routed to the DNS server running inside the Docker container.Note: In some systems, the /etc/resolv.conf file might get regenerated on reboot or when network settings change. If you notice that your changes get removed, you might need additional configuration to make them persistent.
