Terraform Pull Request Automation using Bitbucket

Pull request automation in Terraform configurations, particularly with Bitbucket, helps ensure changes are thoroughly reviewed and approved before merging, reducing errors and enhancing security. This process utilizes Bitbucket Pipelines, a continuous integration and deployment feature, to automate workflows and decrease reliance on manual interventions. The setup involves enabling Bitbucket Pipelines in your repository, configuring a `bitbucket-pipelines.yml` file to define a pipeline using the latest Terraform image, and adding a webhook to trigger the pipeline on pull request creation or updates. Additionally, integrating the Terraform plan output into the pull request can be achieved through a custom Bitbucket app or an existing integration, allowing for direct visibility of changes within the pull request itself.
