What Will I Learn?

• How to make your Terraform code DRY with Terragrunt
• Eliminate code duplication by centralizing common configurations and reusing them across different modules and environments.
• Simplify infrastructure management with Terragrunt's ability to handle complex setups, including multi-environment and multi-account deployments.
• Master the use of hooks and dependency management to automate workflows and ensure smooth execution of Terraform commands.
• Implement best practices for maintaining a clean, modular, and maintainable codebase that scales effortlessly as your infrastructure grows.
• Advanced use cases with Terragrunt
• How to better manage resources as a code with a Terraform
• Structure your Terraform code

Requirements

• Terraform, Linux, Bash, Command line, AWS, Vault
• Basic Knowledge of Terraform: Familiarity with Terraform's core concepts, such as infrastructure as code (IaC), modules, and state management, is essential. Experience with writing and deploying Terraform configurations will help you understand how Terragrunt enhances Terraform workflows
• Experience with Cloud Platforms: Understanding how to deploy infrastructure on cloud platforms like AWS, Azure, or Google Cloud will be beneficial, as the course will involve real-world scenarios using cloud providers
• Version Control and Automation Practices: Basic knowledge of version control systems like Git and automation practices will be helpful for managing Terraform code across multiple environments and versions

Target audience

• DevOps Engineers: Professionals responsible for managing and automating infrastructure who want to streamline their Terraform workflows and handle complex, multi-environment setups more efficiently
• Cloud Engineers: Individuals working with cloud platforms (AWS, Azure, GCP) who need to manage infrastructure as code and are looking to reduce code duplication and improve state management across environments
• Admins, DevOps, Infrastructure Engineers and Developers that manages infrastructure as code
• Terraform Users: People with foundational knowledge of Terraform or similar tools (like OpenTofu) who are seeking to enhance their skills by learning how to make their configurations more modular, reusable, and maintainable using Terragrunt
• Infrastructure Automation Enthusiasts: Those interested in improving their automation practices by learning how to manage dependencies, remote state, and environment configurations in a scalable, DRY manner
• Terraform and Terragrunt users
• Those that manage Infrastructure
