# Agent 09 — Deployment

> DevOps deployment agent. Produces Dockerfile, CI/CD pipeline config, and deployment scripts.

<Info>
  **File:** `agents/sdlc/09-deployment.md` · **Model:** Sonnet · **Tools:** Bash, Read, Write
</Info>

## Purpose

The deployment agent produces deployment artefacts that work the same way in every environment. Every deploy is reversible in under 5 minutes.

## Core principle

> Rollback is not a footnote — it is a first-class deliverable.

## What it produces

* Multi-stage Dockerfile with non-root user
* CI/CD pipeline config (GitHub Actions, CircleCI, etc.)
* Environment-specific configs (dev, staging, production)
* Deploy script with health check + rollback procedure
* `deployment_report.json`

## Sample outputs

```dockerfile theme={null}
# Multi-stage, non-root, production-ready
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production

FROM node:20-alpine
RUN addgroup -S app && adduser -S app -G app
WORKDIR /app
COPY --from=builder /app/node_modules ./node_modules
COPY . .
USER app
EXPOSE 3000
HEALTHCHECK --interval=30s CMD wget -qO- http://localhost:3000/health
CMD ["node", "src/index.js"]
```
