Resolving Azure DevOps Pipeline Terraform Init Failures

Are you facing issues when running terraform init in your Azure DevOps Pipeline? If you've successfully installed Terraform but encounter a failure at the initialization stage, you're not alone. This post aims to address this common problem and guide you through the necessary steps to resolve it.

Understanding the Problem

When you run a pipeline in Azure DevOps that includes Terraform commands, it's crucial to ensure that your working directory is set up correctly. A failure at the init step can arise from a variety of reasons, predominantly stemming from Terraform's inability to locate the required files within your specified directory.

The error message you might see can be misleading:

This indicates a problem with the execution environment rather than the Terraform command itself.

Step-by-Step Solution

1. Check Your Working Directory

It's essential to confirm that your pipeline is pointing to the correct directory where your Terraform configuration files reside. A missing configuration can lead to terraform init failing.

To verify your working directory, you can add a simple check in your pipeline script:

This command lists the contents of your specified working directory. Ensure that your .tf files are present in the output.

2. Ensure the Repository is Checked Out

Another critical step is to ensure that your repository is checked out before any job commands are executed. By default, in a deployment job, the repository isn’t automatically downloaded.

To do this, add the following line to your job:

This line tells Azure DevOps to clone the repository, making your Terraform configuration files available for use in the deployment.

A Working Example

Here’s how your adjusted YAML pipeline might look:

Conclusion

Those steps should help you overcome the initialization failure in your Azure DevOps Pipeline when working with Terraform. Remember to always verify your working directory and ensure that your repository is checked out. Following best practices like these not only simplifies your current task but also helps prevent similar issues in future projects.

If the problem persists after making these adjustments, it may be worth checking your Terraform configuration files for any additional errors or missing parameters.

By systematically addressing these aspects, you can streamline your deployment process with Terraform and ensure your Azure DevOps pipelines function smoothly. Happy scripting!
