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
