# DEVOPS-DEPLOY — Da Ideia para Producao

## Overview

DevOps e deploy de aplicacoes — Docker, CI/CD com GitHub Actions, AWS Lambda, SAM, Terraform, infraestrutura como codigo e monitoramento. Ativar para: dockerizar aplicacao, configurar pipeline CI/CD, deploy na AWS, Lambda, ECS, configurar GitHub Actions, Terraform, rollback, blue-green deploy, health checks, alertas.

## When to Use This Skill

- When you need specialized assistance with this domain

## Do Not Use This Skill When

- The task is unrelated to devops deploy
- A simpler, more specific tool can handle the request
- The user needs general-purpose assistance without domain expertise

## How It Works

> "Move fast and don't break things." — Engenharia de elite nao e lenta.
> E rapida e confiavel ao mesmo tempo.

## Dockerfile Otimizado (Python)

```dockerfile
FROM python:3.11-slim AS builder
WORKDIR /app
COPY requirements.txt .
RUN pip install --no-cache-dir --user -r requirements.txt

FROM python:3.11-slim
WORKDIR /app
COPY --from=builder /root/.local /root/.local
COPY . .
ENV PATH=/root/.local/bin:$PATH
ENV PYTHONUNBUFFERED=1
EXPOSE 8000
HEALTHCHECK --interval=30s --timeout=3s CMD curl -f http://localhost:8000/health || exit 1
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000"]
```

## Docker Compose (Dev Local)

```yaml
version: "3.9"
services:
  app:
    build: .
    ports: ["8000:8000"]
    environment:
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
    volumes:
      - .:/app
    depends_on: [db, redis]
  db:
    image: postgres:15
    environment:
      POSTGRES_DB: auri
      POSTGRES_USER: auri
      POSTGRES_PASSWORD: ${DB_PASSWORD}
    volumes:
      - pgdata:/var/lib/postgresql/data
  redis:
    image: redis:7-alpine
volumes:
  pgdata:
```

## Deploy Commands

```bash

## Build E Deploy

sam build
sam deploy --guided  # primeira vez
sam deploy           # deploys seguintes

## Deploy Rapido (Sem Confirmacao)

sam deploy --no-confirm-changeset --no-fail-on-empty-changeset

## Ver Logs Em Tempo Real

sam logs -n AuriFunction --tail

## Deletar Stack

sam delete
```

## Health Check Endpoint

```python
from fastapi import FastAPI
import time, os

app = FastAPI()
START_TIME = time.time()

@app.get("/health")
async def health():
    return {
        "status": "healthy",
        "uptime_seconds": time.time() - START_TIME,
        "version": os.environ.get("APP_VERSION", "unknown"),
        "environment": os.environ.get("ENV", "production")
    }
```

## Alertas Cloudwatch

```python
import boto3

def create_error_alarm(function_name: str, sns_topic_arn: str):
    cw = boto3.client("cloudwatch")
    cw.put_metric_alarm(
        AlarmName=f"{function_name}-errors",
        MetricName="Errors",
        Namespace="AWS/Lambda",
        Dimensions=[{"Name": "FunctionName", "Value": function_name}],
        Period=300,
        EvaluationPeriods=1,
        Threshold=5,
        ComparisonOperator="GreaterThanThreshold",
        AlarmActions=[sns_topic_arn],
        TreatMissingData="notBreaching"
    )
```

- [ ] Health check endpoint respondendo
- [ ] Logs estruturados (JSON) com request_id
- [ ] Rate limiting configurado
- [ ] CORS restrito a dominios autorizados
- [ ] DynamoDB com backup automatico ativado
- [ ] Lambda com timeout adequado (10-30s)
- [ ] CloudWatch alarmes para erros e latencia
- [ ] Rollback plan documentado
- [ ] Load test antes do lancamento

## Best Practices

- Provide clear, specific context about your project and requirements
- Review all suggestions before applying them to production code
- Combine with other complementary skills for comprehensive analysis

## Common Pitfalls

- Using this skill for tasks outside its domain expertise
- Applying recommendations without understanding your specific context
- Not providing enough project context for accurate analysis
