# Infrastructure Engineer Sub-Skill

**Communication: User's language. Config/code: English.**

## Purpose

Manages infrastructure provisioning, containerization, orchestration, and cloud platforms. Covers Docker, Kubernetes, Terraform, AWS, GCP, and IaC patterns.

---

## Context Discovery

### Auto-Investigation

Detect existing infrastructure from project:

| Signal | How to Check | What It Tells Us |
|--------|--------------|------------------|
| Dockerfile | `Glob("**/Dockerfile")` or `Glob("**/.dockerfile")` | Docker containerization |
| docker-compose | `Glob("**/docker-compose*.yml")` | Multi-container local dev |
| K8s manifests | `Glob("**/k8s/**/*.yaml")` or `Glob("**/kubernetes/*")` | Kubernetes deployment |
| Helm charts | `Glob("**/charts/*")` or `Glob("**/Chart.yaml")` | Helm package management |
| Terraform | `Glob("**/*.tf")` or `Glob("**/terraform/*")` | IaC with Terraform |
| AWS config | `Grep("aws_", "**/*.tf")` or `Glob("**/.aws/*")` | AWS infrastructure |
| GCP config | `Grep("google_", "**/*.tf")` or `Glob("**/.gcp/*")` | GCP infrastructure |
| Cloud init | `Glob("**/cloud-init*.yaml")` | VM provisioning |

**Read existing infrastructure:**
- docker-compose.yml for service architecture
- Kubernetes manifests for deployment patterns
- Terraform files for cloud resources
- README for infrastructure setup instructions

### Discovery Questions

#### Q1: Infrastructure Layer

```yaml
question: "What infrastructure layer do you need help with?"
header: "Focus"
multiSelect: false
options:
  - label: "Containerization (Docker)"
    description: "Dockerfile, image optimization, local development"
  - label: "Orchestration (Kubernetes, Helm)"
    description: "K8s deployments, services, scaling, Helm charts"
  - label: "Infrastructure as Code (Terraform)"
    description: "Cloud provisioning, modules, state management"
  - label: "Cloud platform (AWS or GCP)"
    description: "Compute, storage, networking, managed services"
```

#### Q2: Deployment Stage

```yaml
question: "What stage is your infrastructure at?"
header: "Maturity"
multiSelect: false
options:
  - label: "Local dev only (docker-compose)"
    description: "Need to containerize or improve local setup"
  - label: "Manual deployment (no automation)"
    description: "Need IaC or orchestration"
  - label: "Basic K8s or cloud (needs optimization)"
    description: "Running but needs scaling, monitoring, cost optimization"
  - label: "Multi-environment (staging, prod)"
    description: "Need consistency, GitOps, or advanced patterns"
```

#### Q3: Cloud Provider

```yaml
question: "Which cloud provider are you using?"
header: "Platform"
multiSelect: false
options:
  - label: "AWS"
    description: "EC2, ECS, Lambda, S3, networking"
  - label: "GCP"
    description: "GKE, Cloud Run, Compute, storage"
  - label: "Multi-cloud or cloud-agnostic"
    description: "Need portable IaC with Terraform"
  - label: "On-premise or bare metal"
    description: "Self-hosted Kubernetes or VMs"
```
