Automate local DNS with Bind and Terraform

Doing manual configuration is a thing of the past! With Terraform, I’m now managing all my local DNS entries fully automatically. In this YouTube video, I’m going to show you exactly how I’ve done that. If you’re new to this, I recommend checking out my other video first. All the commands and configs are available on GitHub.

I'm loving your content! It's right on time for me as a rebuild my labs! I would love to see you cover Hashicorp Vault for keeping Terraform/Ansible secrets!

I am happy to watch all your videos. And I'm learning. go go go!

That's a really cool way of handling DNS records. I didn't know terraform could handle the bind config on its own.
I use my OPNsense for DNS and create the records with a combination of terraform and ansible. I wrote a small playbook that creates an A record and several CNAME records which gets executed in my VM terraform module. That way I have the benefit of the lifecycle management from terraform plus the easy DNS setup without a dedicated VM for it. Combined with CI/CD it's just the perfect setup for a constantly changing homelab.

This is really interesting! One thing I would like to see more of is that you do dual stack configuration. A lot of us use IPv6 to talk directly to our machines without the hastle of NAT!

Nice approach to manage the dns records together with your IAC via Terraform.
I'm currently using terraform to manage virtual machines and an Ansible role to install and configure bind and it's zone files. As long as my Ansible inventory hosts are maintained correctly, my dns records will be as well ;)

Amazing video! Very nice content, well explained and very professional. Keep it up!

[wahabhabeeb]

Awesome! I am try that right away. Thanks for sharing

If you're big on Terraform, I think that's a great solution. I opted for Technitium DNS and wrote a small Docker app for updating through the built-in API.

Nice tutorial, I'll totally set this up once I have my homelab setup ready. Btw have you ever used terraform cloud? It's pretty good ngl, have you seen it's latest update that it gives you one free runner to use for on premises terraform applies through terraform cloud?

Seriously Christan? I was looking up this topic and you posted this 3 hours ago!

Awesome video, I have refactored my Terraform scripts to include now the DNS A records of my hosts in my homelab. One question though: how do you generate the records for PTR records?

[francescolaporta]

Great video, interesting! Is there a web interface to insert new records into zones that interfaces with terraform+bind?

[youtubegarbageu]

where is video for using letsencrypt for the apps running on the internal networks?

[hansaya]

What I have done is use pfsense to automate DNS. I even got k3s to automatically update my dns entries

[AndrewMay-GG]

I'm having a problem with "apparmor", when making the modification with terraform, bind returns an error when creating the file, I verified that the ubuntu image does not allow the application to write to this directory.

[michaelventarola]

I am able to add A records, but these records are not updated in my zone files. They are in a zone file with a jnl extention. How do I get thezone fles updated?

[ahmadmiqdaadabdulaziz]

Is there any GUI for bind9 ? something like GoDaddy DNS manager / cpanel DNS manager ? If you plan to start that project, I would love to see it

[monsterhuntfreak]

I just use FreeIPA for DNS Management. Once I add the server/ client to the Domain it automatically gets added as a DNS Entry

[HackerConsole]

Hello, how do you solve the problem of creating the journal?

[pnxtjwi]

"What I really hate in the IT is manual configuration.

So I took all the records from a huge Bind config file and put them all to another even bigger Terraform config file.

And I made a video about it."
