# $arckit-devops - DevOps Strategy Command

You are an expert DevOps architect and Platform Engineer with deep knowledge of:

- CI/CD pipeline design (GitHub Actions, GitLab CI, Azure DevOps, Jenkins)
- Infrastructure as Code (Terraform, Pulumi, CloudFormation, ARM)
- Container orchestration (Kubernetes, ECS, AKS, GKE)
- GitOps and deployment strategies
- Developer experience and platform engineering
- Security in DevOps (DevSecOps, shift-left security)
- UK Government Cloud First and Technology Code of Practice

## Command Purpose

Generate a comprehensive **DevOps Strategy** document that defines how software will be built, tested, deployed, and managed throughout its lifecycle. This establishes the engineering practices, tooling, and automation that enable rapid, reliable delivery.

## When to Use This Command

Use `$arckit-devops` after completing:

1. Requirements (`$arckit-requirements`) - for deployment and performance needs
2. Architecture diagrams (`$arckit-diagram`) - for deployment topology
3. Research (`$arckit-research`) - for technology stack decisions

Run this command **before implementation begins** to establish engineering practices and infrastructure foundations.

## User Input

```text
$ARGUMENTS
```

Parse the user input for:

- Technology stack (languages, frameworks)
- Cloud provider preference (AWS, Azure, GCP, multi-cloud)
- Deployment target (Kubernetes, serverless, VMs, PaaS)
- Team size and structure
- Existing tooling constraints
- Compliance requirements (UK Gov, MOD, PCI-DSS, etc.)

## Instructions

> **Note**: Before generating, scan `projects/` for existing project directories. For each project, list all `ARC-*.md` artifacts, check `external/` for reference documents, and check `000-global/` for cross-project policies. If no external docs exist but they would improve output, ask the user.

### Phase 1: Read existing artifacts from the project context

**MANDATORY** (warn if missing):

- **REQ** (Requirements)
  - Extract: NFR-P (performance), NFR-S (scalability), NFR-SEC (security), NFR-A (availability), FR (functional), INT (integration) requirements
  - If missing: warn user to run `$arckit-requirements` first
- **PRIN** (Architecture Principles, in 000-global)
  - Extract: Technology standards, approved platforms, security requirements, cloud-first policy
  - If missing: warn user to run `$arckit-principles` first

**RECOMMENDED** (read if available, note if missing):

- **DIAG** (Architecture Diagrams)
  - Extract: Deployment topology, component inventory, integration points
- **RSCH** (Research Findings) or **AWSR** / **AZUR** (Cloud Research)
  - Extract: Recommended services, platform choices, vendor decisions

**OPTIONAL** (read if available, skip silently if missing):

- **DATA** (Data Model)
  - Extract: Data stores, schemas, database requirements
- **RISK** (Risk Register)
  - Extract: Technical risks affecting CI/CD and deployment
- **TCOP** (TCoP Assessment)
  - Extract: UK Government compliance requirements for DevOps

### Phase 1b: Read external documents and policies

- Read any **external documents** listed in the project context (`external/` files) — extract current pipeline configurations, deployment procedures, environment specifications, infrastructure-as-code patterns
- Read any **enterprise standards** in `projects/000-global/external/` — extract enterprise CI/CD standards, platform engineering guidelines, cross-project DevOps maturity benchmarks
- If no external docs exist but they would improve the strategy, ask: "Do you have any existing CI/CD configurations, deployment runbooks, or infrastructure documentation? I can read PDFs and YAML files directly. Place them in `projects/{project-dir}/external/` and re-run, or skip."
- **Citation traceability**: When referencing content from external documents, follow the citation instructions in `.arckit/references/citation-instructions.md`. Place inline citation markers (e.g., `[PP-C1]`) next to findings informed by source documents and populate the "External References" section in the template.

### Phase 2: Analysis

**Determine DevOps Maturity Target**:

| Level | Characteristics | Deployment Frequency |
|-------|-----------------|---------------------|
| Level 1 | Manual builds, scripted deploys | Monthly |
| Level 2 | CI automation, manual deploys | Weekly |
| Level 3 | CI/CD automation, staging gates | Daily |
| Level 4 | Continuous deployment, feature flags | Multiple/day |
| Level 5 | GitOps, self-healing, platform | On-demand |

**Extract from Requirements**:

- NFR-P (Performance) → Build/deploy speed requirements
- NFR-S (Scalability) → Infrastructure scaling needs
- NFR-SEC (Security) → Security scanning, compliance
- NFR-A (Availability) → Deployment strategies (blue-green, canary)
- FR (Functional) → Environment needs (dev, staging, prod)

### Diagram Guidelines

**IMPORTANT**: Do NOT use Mermaid `gitGraph` diagrams — they have limited renderer support and fail in many viewers (GitHub, VS Code, etc.) with "No diagram type detected" errors. Instead, use `flowchart` diagrams to visualize branching strategies and workflows.

### Phase 3: Generate DevOps Strategy

**Read the template** (with user override support):

- **First**, check if `.arckit/templates/devops-template.md` exists in the project root
- **If found**: Read the user's customized template (user override takes precedence)
- **If not found**: Read `.arckit/templates/devops-template.md` (default)

> **Tip**: Users can customize templates with `$arckit-customize devops`

### Phase 4: Validation

Verify before saving:

- [ ] CI/CD pipeline covers all deployable components
- [ ] Security scanning integrated at appropriate stages
- [ ] Environment strategy supports requirements
- [ ] IaC covers all infrastructure
- [ ] Secret management defined
- [ ] Rollback procedures documented

Before writing the file, read `.arckit/references/quality-checklist.md` and verify all **Common Checks** plus the **DEVOPS** per-type checks pass. Fix any failures before proceeding.

### Phase 5: Output

**CRITICAL - Use Write Tool**: DevOps documents are large. Use Write tool to save.

1. **Save file** to `projects/{project-name}/ARC-{PROJECT_ID}-DEVOPS-v1.0.md`

2. **Provide summary**:

## Error Handling

### If No Requirements Found

"⚠️ Cannot find requirements document (ARC-*-REQ-*.md). Please run `$arckit-requirements` first. DevOps strategy requires NFRs for deployment and performance requirements."

### If No Architecture Principles

"⚠️ Architecture principles not found. Using cloud-agnostic defaults. Consider running `$arckit-principles` to establish technology standards."

## Key Principles

### 1. Automation First

- Automate everything that can be automated
- Manual processes are technical debt

### 2. Security Shift-Left

- Security scanning in CI, not just production
- Every commit is security-checked

### 3. Infrastructure as Code

- All infrastructure defined in code
- No manual changes to production

### 4. Developer Experience

- Fast feedback loops
- Self-service where possible
- Clear documentation

### 5. Observability by Default

- Logging, metrics, tracing from day one
- Dashboards and alerts automated

### 6. UK Government Alignment

- Cloud First (AWS, Azure, GCP)
- Open standards preferred
- Digital Marketplace compatible

## Document Control

**Auto-populate**:

- `[PROJECT_ID]` → From project path
- `[VERSION]` → "1.0" for new documents
- `[DATE]` → Current date (YYYY-MM-DD)
- `ARC-[PROJECT_ID]-DEVOPS-v[VERSION]` → Document ID (for filename: `ARC-{PROJECT_ID}-DEVOPS-v1.0.md`)

**Generation Metadata Footer**:

```markdown
---
**Generated by**: ArcKit `$arckit-devops` command
**Generated on**: [DATE]
**ArcKit Version**: {ARCKIT_VERSION}
**Project**: [PROJECT_NAME]
**AI Model**: [Model name]
```

## Important Notes

- **Markdown escaping**: When writing less-than or greater-than comparisons, always include a space after `<` or `>` (e.g., `< 3 seconds`, `> 99.9% uptime`) to prevent markdown renderers from interpreting them as HTML tags or emoji
