Import Infrastructure As Code

What Is This?

Import Infrastructure as Code is a development skill that automates the conversion of existing cloud infrastructure into IaC declarations using tools like Terraform, Pulumi, or CloudFormation. This skill scans deployed resources across cloud providers, analyzes their configurations, and generates corresponding infrastructure code that accurately represents the current state. It bridges the gap between manually created infrastructure and code-managed infrastructure by reverse-engineering deployments into maintainable, version-controlled code.

The skill handles complex dependencies between resources, capturing relationships like security group rules referencing other security groups or load balancers connected to specific target groups. It produces idiomatic code for the target IaC tool, including proper resource naming, variable extraction, and modular organization, eliminating the tedious manual process of translating existing infrastructure into code definitions.

Who Should Use This

DevOps engineers inheriting legacy infrastructure without code definitions, cloud architects migrating projects to IaC practices, platform teams standardizing infrastructure management, and consultants documenting client environments. Essential for organizations transitioning from manual cloud console management to automated infrastructure workflows.

Why Use It?

Problems It Solves

Eliminates the error-prone process of manually writing IaC for existing resources, which often results in drift between code and reality. Prevents teams from abandoning IaC adoption due to the overwhelming task of codifying large existing environments. Reduces the risk of recreating infrastructure from scratch by preserving exact current configurations. Provides immediate visibility into all deployed resources that might not be documented elsewhere and accelerates disaster recovery planning by ensuring all infrastructure has code backups.

Core Highlights

• Automatic resource discovery across cloud providers
• Accurate dependency graph construction
• Code generation in multiple IaC formats
• Support for AWS, Azure, GCP, and other providers
• Variable extraction for reusable parameters
• Module organization for maintainability
• State file generation for import operations
• Validation of generated code against actual infrastructure

How to Use It?

Basic Usage

Authenticate the skill with your cloud provider using appropriate credentials. Specify the scope of resources to import, such as a particular region, resource group, or project. Select the target IaC tool format for code generation. Execute the import process, which scans resources and generates code files. Review the generated code for accuracy and organization, then run the import command in your IaC tool to synchronize state with existing resources.

Real-World Example

A company has been running production infrastructure on AWS for three years, all created through the console. A new DevOps engineer joins and needs to implement IaC. Using this skill, they import all production VPCs, EC2 instances, RDS databases, and associated networking components into Terraform code. The generated code is organized into modules by service, with variables extracted for environment-specific values, allowing the team to manage infrastructure through code while preserving the exact current production setup.

Advanced Tips

Import resources incrementally by service or logical grouping rather than all at once to manage complexity. Review and refactor generated code to improve naming conventions and structure before committing. Combine with policy-as-code tools to validate that imported infrastructure meets security standards. Set up regular import scans to detect manually created resources that bypass IaC workflows.

When to Use It?

Use Cases

Adopting infrastructure as code for existing environments. Documenting undocumented infrastructure. Migrating between IaC tools or cloud providers. Creating disaster recovery plans based on current deployments. Auditing cloud resource usage and configurations. Onboarding new team members with accurate infrastructure documentation. Establishing version control for infrastructure changes.

Important Notes

Requirements

Valid cloud provider credentials with read access to resources. IaC tool installed locally for testing generated code. Understanding of target IaC tool syntax and concepts. Sufficient API rate limits for resource discovery operations. Network access to cloud provider APIs.

Usage Recommendations

Always import into a separate branch or directory first to review before merging. Test generated code in a non-production environment before applying changes. Document any manual adjustments made to generated code. Establish naming conventions before importing to guide refactoring. Back up any existing IaC state files before running imports.

Limitations

Cannot capture resources created in ways that leave no API footprint. May struggle with custom or proprietary cloud configurations. Generated code reflects current state, not historical evolution. Does not capture manual processes or runbooks associated with infrastructure. Large environments may hit API rate limits during import scans. Some resource types may not be supported depending on IaC tool capabilities. Sensitive data in configurations may require manual redaction.
