infrastructure-iac SKILL.md skillA
infrastructure-iac from d-padmanabhan/agent-engineering-handbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add d-padmanabhan/agent-engineering-handbook/infrastructure-iac@git:20260607.cd1b06dPins git:20260607.cd1b06d in mdr.lock. Pin the fingerprint instead.

Infrastructure as Code best practices for Terraform, Docker, Ansible, and CloudFormation. Covers secure-by-default configurations, multi-stage builds, state management, and modular patterns. Use when working with .tf, Dockerfile, docker-compose.yml, .yaml/.yml Ansible files, CloudFormation templates, or when asking about IaC, containers, or infrastructure automation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Infrastructure as Code
## Guiding Principles
1. **Security First**: Non-root users, minimal images, secret management
2. **Reproducibility**: Pin versions, deterministic builds, locked dependencies
3. **Modularity**: Reusable modules, DRY patterns, clear interfaces
4. **State Management**: Remote state, locking, backup strategies
## Tool Selection
| Use Case | Tool |
|----------|------|
| Cloud infrastructure | Terraform |
| Containers | Docker |
| Configuration management | Ansible |
| AWS-native IaC | CloudFormation |
## Terraform Quick Reference
### Essential Commands
```bash
terraform init # Initialize working directory
terraform plan # Preview changes
terraform plan -out=tfplan # Save plan for apply
terraform apply tfplan # Apply saved plan
terraform fmt -recursive # Format all files
terraform validate # Validate configuration
```
### Critical Patterns
```hcl
# 1. Pin provider versions
terraform {
required_version = ">= 1.6.0"
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 5.60"
}
}
}
# 2. Use for_each for stability
…Read the whole file at its exact version.
How to install
mdr add d-padmanabhan/agent-engineering-handbook/infrastructure-iac@sha256:74f1eb1961f8a4e3The line at the top of this page pins the label git:20260607.cd1b06d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
