Introduction

Jenkins is a popular automation server that can be used for continuous integration and continuous deployment (CI/CD) of Terraform code. In this blog, we will explore how to use Jenkins to automate Terraform pull requests.

Overview of Terraform Pull Requests

Pull requests are an important aspect of collaborative software development. They enable developers to suggest changes to a codebase and have them reviewed before they are merged into the main branch. Terraform pull requests are no different. Developers can make changes to Terraform code and submit pull requests for review. However, the process of reviewing Terraform pull requests can be time-consuming and error-prone. To streamline this process, we can automate it using Jenkins.

Setting up Jenkins for Terraform Pull Request Automation

To set up Jenkins for Terraform pull request automation, you need to follow these steps:

  1. Install Jenkins on a server.
  2. Install the Terraform plugin in Jenkins.
  3. Configure Jenkins to use your source code repository (such as Git) for Terraform code.
  4. Create a new Jenkins job that listens for pull requests on the Terraform repository.
  5. Configure the Jenkins job to run Terraform plan on the pull request code.
  6. Configure the Jenkins job to report the Terraform plan output to the pull request.
  7. Configure the Jenkins job to merge the pull request if the Terraform plan is successful.

Automating Terraform Pull Request Reviews

Now that you have set up Jenkins for Terraform pull request automation, the process of reviewing pull requests becomes much simpler. Whenever a pull request is submitted, Jenkins will automatically run a Terraform plan on the code. The output of the Terraform plan will be reported to the pull request, making it easy for reviewers to see what changes will be made if the pull request is merged.

If the Terraform plan is successful, Jenkins can automatically merge the pull request. This saves time and effort for the development team and ensures that the process is consistent and error-free.
