# Cloud Infrastructure & Shell Tooling
Unified skill for cloud infrastructure, DevOps, and shell scripting. Infrastructure should be reproducible, version-controlled, and immutable. Shell scripts are infrastructure glue -- they deserve the same rigor as application code.
## Task Router
### Cloud & DevOps
| Task | Reference |
|------|-----------|
| Dockerfiles, images, Compose, container security | [references/docker.md](references/docker.md) |
| Kubernetes objects, Helm, troubleshooting | [references/kubernetes.md](references/kubernetes.md) |
| CRDs, operators, admission webhooks, Velero, DR, vCluster | [references/kubernetes-advanced.md](references/kubernetes-advanced.md) |
| Terraform modules, state, workspaces | [references/terraform.md](references/terraform.md) |
| GitHub Actions, GitLab CI, pipelines | [references/cicd.md](references/cicd.md) |
| AWS/GCP/Azure services, architectures | [references/cloud-providers.md](references/cloud-providers.md) |

### Shell Scripting
| Task | Reference |
|------|-----------|
| Defensive patterns, traps, strict mode, atomicity | [references/defensive.md](references/defensive.md) |
| BATS testing, mocking, fixtures | [references/bats-testing.md](references/bats-testing.md) |
| ShellCheck config and suppression | [references/shellcheck.md](references/shellcheck.md) |
| Argument parsing (getopts, getopt, subcommands) | [references/argument-parsing.md](references/argument-parsing.md) |
| systemd services and timers | [references/systemd-services.md](references/systemd-services.md) |
| Text processing (awk, sed, pipelines) | [references/text-processing.md](references/text-processing.md) |
| Production logging (structured, JSON, syslog) | [references/logging-production.md](references/logging-production.md) |
| HTTP/networking (curl, wget, retry, APIs) | [references/http-networking.md](references/http-networking.md) |
| Parallel execution (xargs, GNU parallel, pools) | [references/parallel-execution.md](references/parallel-execution.md) |
| Advanced debugging (PS4, BASH_XTRACEFD, traps) | [references/debugging-advanced.md](references/debugging-advanced.md) |
## Core Principles
1. **Infrastructure as Code** -- every resource in version-controlled files, no manual console clicks
2. **Immutable infrastructure** -- replace, don't patch; build new images instead of SSHing in
3. **Least privilege** -- minimum permissions for every service account, IAM role, container
4. **Strict shell mode** -- every script starts with `set -Eeuo pipefail`, quotes all variables
5. **Observe everything** -- metrics, logs, traces; alert on symptoms, not causes
6. **GitOps** -- git is single source of truth; infra changes go through PRs
7. **Test shell scripts** -- BATS makes it easy; run ShellCheck in CI as pre-commit hook
## Layer 3 Skills
- **deploy-vercel** — Vercel deployment and configuration
- **deploy-modal** — Modal serverless GPU deployment
- **deploy-convex** — Convex backend deployment
- **monitoring-sentry** — Sentry error monitoring and alerting
- **testing-quality** — BATS shell testing, CI/CD test pipelines
