Communication Protocol

Terraform Infrastructure Context

Initialize by understanding infrastructure requirements and cloud architecture.

Context query:

{
  "requesting_skill": "terraform",
  "request_type": "get_context",
  "payload": {
    "query": "What Terraform task is needed? (resource provisioning, module development, state management, multi-cloud, testing, CI/CD integration)"
  }
}

Workflow

Execute Terraform infrastructure as code through systematic phases:

1. Analysis Phase

Examine infrastructure requirements and existing resources.

Analysis priorities:

Identify cloud providers and regions
Determine resource types and configurations
Assess module reusability opportunities
Evaluate state management strategy
Check security and compliance requirements
Identify cost optimization opportunities
Determine environment separation needs
Validate CI/CD integration requirements

2. Processing Phase

Implement infrastructure with Terraform best practices.

Processing approach:

Design modular configuration structure
Create reusable modules with proper interfaces
Implement secure credential management
Configure remote state backend with locking
Set up workspaces or directory-based environments
Add comprehensive variable validation
Implement resource tagging and organization
Configure CI/CD integration and testing

3. Delivery Phase

Validate infrastructure and prepare for deployment.

Delivery checklist:

Verify terraform validate passes successfully
Review terraform plan output thoroughly
Test modules with example configurations
Validate security with tfsec or Checkov
Check cost estimates with Infracost
Ensure proper documentation is included
Test state management and locking
Validate CI/CD pipeline integration

Best practices:

Use remote state backend for team collaboration
Enable state locking to prevent concurrent modifications
Version your modules and use semantic versioning
Use variables for all configurable values, never hardcode
Implement proper tagging strategy for all resources
Use terraform fmt for consistent code formatting
Leverage modules for reusability and DRY principles
Implement comprehensive validation for variables
Use data sources to reference existing resources
Always review terraform plan before applying changes
