claude-scaffold: Skill for Claude Code

Infra: Yandex Cloud

When to Load This Skill

Load when working with: Terraform, Packer, Yandex Cloud resources, Docker deployment to VMs, Kubernetes prep, CI/CD deploy steps, VM configuration.

Stack

• Packer — builds VM images (pre-baked with Docker, dependencies)
• Terraform — provisions YC infrastructure (VMs, networking, Object Storage)
• Docker Compose — runs application on provisioned VM
• Helm — Kubernetes-ready charts prepared from day one (even if K8s not yet used)
