How to Fix the DNS-1035 Error in Gitlab Installation with Terraform

If you've tried to install Gitlab using Terraform and stumbled upon a DNS-1035 error, you're not alone. This can be particularly frustrating, especially when you believe you're following the correct protocols. In this guide, we'll explore what causes this error and provide a clear, step-by-step solution to resolve it.

Understanding the DNS-1035 Error

The DNS-1035 error typically arises due to invalid naming conventions in Kubernetes service names. The error message you received highlights that the name you provided, test-gitlab.postgres.database.azure.com-headless, does not meet the following criteria:

Must consist of lowercase alphanumeric characters or -

Must start with an alphabetic character

Must end with an alphanumeric character

Here is the specific error message:

The Cause of the Error

While it may seem that your name adheres to the DNS-1035 regulations (as it uses lowercase characters), the addition of -headless to the hostname hints at a deeper problem. This name alteration isn't something you're manually setting, and it can be perplexing when troubleshooting. The error typically occurs due to configurations that include persistent storage setups.

Configuration Context

Here’s the configuration you had attempted with your values.yaml file, which contains critical information for the PostgreSQL service:

The Solution

For many users, the solution is relatively straightforward. The issue can be resolved by explicitly disabling the PostgreSQL installation within your configuration. By indicating you do not want PostgreSQL installed via the Helm chart, you prevent any automatic naming conventions from interfering.

Step-by-Step Fix

Open your values.yaml file: This file holds the configurations for your Gitlab setup using Terraform and Helm.

Locate the PostgreSQL section.

Add or modify the following configuration setting:

Your revised values.yaml should look like this:

Save the file and re-run your Terraform command to initiate the Gitlab installation.

Conclusion

Encountering the DNS-1035 error during Gitlab installation can be daunting, but with these clear steps, you can easily resolve the issue. By disabling the automatic PostgreSQL installation in your configuration, you maintain control over the service naming and prevent the automatic addition of undesired suffixes.
