Terraform CI/CD Pipelines with GitHub Actions Learn how to automate Terraform workflows with GitHub Actions and improve your Continuous Integration/Continuous Deployment (CI/CD) pipeline. TL;DR Understand the benefits of automating Terraform workflows. Set up a Terraform CI/CD pipeline using GitHub Actions. Learn how to use Terraform Actions to automate Terraform workflows. Deploy to AWS Elastic Container Service (ECS) using GitHub Actions. Why Automate Terraform Workflows? As discussed in "The Ephemeral Infrastructure Paradox" , automating Terraform workflows is crucial to manage the identities of short-lived systems. This article will focus on automating Terraform workflows with GitHub Actions. Terraform and GitHub Actions GitHub Actions is a powerful tool that allows us to automate software development workflows directly in our repository. Terraform, on the other hand, is an Infrastructure as Code (IaC) tool that enables us to manage our infrastructur...

Terraform State Management, Locking, and Backups: Best Practices for DevOps Engineers As DevOps engineers, we've all been there - stuck in a 3 a.m. on-call rotation, trying to troubleshoot a Terraform state lock that won't budge. In this article, we'll explore the best practices for Terraform state management, locking, and backups, and provide you with the tools and knowledge to avoid these common pitfalls. TL;DR Use a state backend like S3 or DynamoDB to store your Terraform state. Lock your Terraform state using a lock ID to prevent concurrent changes. Backup your Terraform state regularly to prevent data loss. Use a Terraform module to create a backup plan for your AWS resources. Why State Management Matters When you're working with Terraform, your state file is the single source of truth for your infrastructure configuration. If your state file becomes corrupted or lost, you'll be left with a mess of broken infrastructure and a lot of headac...

Designing Terraform Modules for Platform Teams As platform teams build and manage complex cloud infrastructure, designing reusable and modular Terraform configurations becomes increasingly important. In this article, we'll explore best practices for designing Terraform modules that promote standardization, modularity, and repeatability in your cloud infrastructure. TL;DR Design Terraform modules with standardization and modularity in mind Use Terraform modules to promote repeatability and reduce complexity Follow best practices for naming, structuring, and documenting Terraform modules Use Terraform modules to manage dependencies and reduce drift Test and validate Terraform modules before deploying them to production Why Terraform Modules Matter When building and managing complex cloud infrastructure, platform teams often face challenges related to standardization, modularity, and repeatability. Terraform modules can help address these challenges by providing a reus...
