DAY 1

Advanced Terraform Syntax and Constructs

• Deep dive into Terraform syntax
• Advanced loops with for_each and count
• Have 3 level deep advanced examples
• Utilizing maps and lists for dynamic configurations
• Advanced usage of maps(one map deploying many infrastructures examples, with maps feeding each other examples)- multi structures deep
• Get values dynamically, and reference another map example
• Use of distinct, flatten in maps and lists

Expressions and Dynamic Configurations

• Basic expressions and their use cases
• Advanced expressions for complex infrastructure setups-(add a few advanced examples)
• Practical exercises on expressions

Terraform Modules Best Practices

• Local vs shared modules: When to use each
• Structuring modules for reusability and maintainability
• examples of fully dynamic modules, to have them central and have one place to update
• Versioning and managing module sources

DAY 2

Running Terraform Locally

• Setting up a local Terraform environment
• Running and testing Terraform code on local machines
• Local development best practices

Terraform Best Practices and Patterns

• Review of instance index keys for state management
• Best practices for writing and organizing Terraform code
• Ensuring idempotency and minimizing side effects

DAY 3

Handling Circular Dependencies

• Identifying and resolving circular dependencies
• Refactoring code to prevent dependency cycles
• Advanced techniques for dependency management

Managing Terraform State

• Importing resources and understanding the state file
• Importing resources that belong to index keys
• State locking, state backends and remote state management
• Handling state file in distributed environments

Keeping Up with Terraform Updates

• Reviewing documentation alongside new Terraform releases
• Strategies for upgrading Terraform versions
• Dealing with deprecations and migration paths

Integrating Terraform with CI/CD Pipelines

• Overview of YAML and pipeline configurations
• Setting up Terraform with popular CI/CD tools
• Automating Terraform workflows in pipelines

DAY 4

Advanced Troubleshooting and Debugging

• Systematic approaches to troubleshooting Terraform plans and applies
• Debugging common and advanced errors in Terraform
• Using logs and verbose output for error resolution

Outputs and Data Flow in Terraform

• Understanding and utilizing outputs in Terraform
• Data flow between modules and root configurations
• Securing sensitive information in outputs
• Differentiating on when to use depends on and also data sources

Conditional Logic in Terraform

• Writing conditional statements with count, for_each, and if
• Dynamically deploying of resources with for each basic to advanced
• Conditional creation of resources
• Use cases for conditional logic in modules
