+# Dockerfile K8s Optimization Report
+
+## Executive Summary
+
+Os Dockerfiles atuais funcionam, mas **NÃO estão otimizados para produção em Kubernetes**. Principais problemas:
+
+- ⚠️ **Segurança**: Todos rodam como root
+- ⚠️ **Graceful Shutdown**: CMD não propaga sinais corretamente
+- ⚠️ **Redundância**: HEALTHCHECKs duplicados (K8s já tem probes)
+- ⚠️ **Cache de Layers**: Oportunidades de otimização perdidas
+
+## Problemas por Dockerfile
+
+### 1. python/Dockerfile.server
+
+**Problemas Críticos:**
+```dockerfile
+# LINHA 78 - ❌ PROBLEMA
+CMD sh -c "python -m uvicorn src.server.main:socket_app --host 0.0.0.0 --port ${ARCHON_SERVER_PORT} --workers 1"
+
+# Problemas:
+# 1. sh -c não propaga SIGTERM para o processo Python
+# 2. Kubernetes rolling updates podem falhar ou ter downtime
+# 3. Conexões podem ser abortadas abruptamente
+```
+
+**Solução:**
+```dockerfile
+# ✅ CORRETO - Exec form com array
+CMD ["python", "-m", "uvicorn", "src.server.main:socket_app", \
+     "--host", "0.0.0.0", "--port", "8181", "--workers", "1"]
+
+# Se precisar de variável de ambiente:
+CMD ["sh", "-c", "exec python -m uvicorn src.server.main:socket_app --host 0.0.0.0 --port ${ARCHON_SERVER_PORT}"]
+```
+
+**Outras Melhorias:**
+
+```dockerfile
+# REMOVER linhas 74-75 (HEALTHCHECK redundante)
+# K8s já tem liveness/readiness probes definidos
+
+# ADICIONAR antes do COPY (depois da linha 56):
+RUN groupadd -r appuser -g 1001 && \
+    useradd -r -g appuser -u 1001 appuser && \
+    mkdir -p /app && chown -R appuser:appuser /app
+
+# ADICIONAR antes do CMD (linha 77):
+USER appuser
+
+# OTIMIZAR CACHE - Mover COPY tests/ para DEPOIS se não for necessário em produção
+```
+
+### 2. python/Dockerfile.mcp
+
+**Problemas:**
+```dockerfile
+# LINHA 42 - ❌ Roda como root, sem healthcheck
+CMD ["python", "-m", "src.mcp_server.mcp_server"]
+```
+
+**Solução Completa:**
+```dockerfile
+# ADICIONAR depois da linha 30:
+RUN groupadd -r appuser -g 1001 && \
+    useradd -r -g appuser -u 1001 appuser && \
+    chown -R appuser:appuser /app
+
+# ADICIONAR antes do CMD (linha 41):
+USER appuser
+
+# CMD já está correto (exec form)
+```
+
+### 3. python/Dockerfile.agents
+
+**Problemas Similares ao MCP:**
+```dockerfile
+# LINHA 34 - ❌ Roda como root
+CMD sh -c "python -m uvicorn src.agents.server:app --host 0.0.0.0 --port ${ARCHON_AGENTS_PORT}"
+
+# LINHAS 30-31 - ❌ HEALTHCHECK redundante para K8s
+```
+
+**Solução:**
+```dockerfile
+# REMOVER linhas 30-31 (HEALTHCHECK)
+
+# ADICIONAR depois da linha 22:
+RUN groupadd -r appuser -g 1001 && \
+    useradd -r -g appuser -u 1001 appuser && \
+    chown -R appuser:appuser /app
+
+# ADICIONAR antes do CMD (linha 33):
+USER appuser
+
+# CORRIGIR CMD (linha 34):
+CMD ["sh", "-c", "exec python -m uvicorn src.agents.server:app --host 0.0.0.0 --port ${ARCHON_AGENTS_PORT}"]
+```
+
+### 4. archon-ui-main/Dockerfile.production
+
+**Problemas:**
+```dockerfile
+# LINHA 41-42 - ❌ HEALTHCHECK redundante
+HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
+    CMD wget --no-verbose --tries=1 --spider http://localhost:3737/ || exit 1
+
+# Nginx roda como root por padrão
+```
+
+**Solução:**
+```dockerfile
+# REMOVER linhas 41-42 (HEALTHCHECK)
+
+# ADICIONAR depois da linha 29:
+# Configurar nginx para rodar como non-root
+RUN addgroup --system --gid 1001 nginx && \
+    adduser --system --uid 1001 --gid 1001 nginx && \
+    chown -R nginx:nginx /usr/share/nginx/html /var/cache/nginx /var/log/nginx && \
+    touch /var/run/nginx.pid && \
+    chown nginx:nginx /var/run/nginx.pid
+
+# ADICIONAR antes do CMD (linha 44):
+USER nginx
+
+# MODIFICAR nginx.conf para ouvir em porta não-privilegiada (>1024)
+# Ou manter 3737 e usar CAP_NET_BIND_SERVICE no K8s
+```
+
+## Otimizações de Cache de Layers
+
+### Dockerfile.server - Otimização
+
+```dockerfile
+# Ordem atual desperdiça cache se código muda
+COPY src/server/ src/server/
+COPY tests/ tests/
+
+# ✅ MELHOR: Copiar apenas o necessário para produção
+COPY src/server/ src/server/
+COPY src/__init__.py src/
+
+# Se tests/ for necessário APENAS para dev, remover do build de produção
+```
+
+### Todos os Dockerfiles Python
+
+```dockerfile
+# ADICIONAR após instalação de dependências:
+# Limpar cache do pip/uv
+RUN rm -rf ~/.cache/pip ~/.cache/uv
+```
+
+## Configuração K8s Necessária
+
+### SecurityContext nos Deployments
+
+```yaml
+# Adicionar em TODOS os deployments (k8s-manifests-complete.yaml):
+spec:
+  template:
+    spec:
+      securityContext:
+        runAsNonRoot: true
+        runAsUser: 1001
+        runAsGroup: 1001
+        fsGroup: 1001
+      containers:
+      - name: server
+        securityContext:
+          allowPrivilegeEscalation: false
+          capabilities:
+            drop:
+              - ALL
+          readOnlyRootFilesystem: false  # true depois de ajustar volumes
+```
+
+### Graceful Shutdown (Deployment spec)
+
+```yaml
+spec:
+  template:
+    spec:
+      terminationGracePeriodSeconds: 30  # Adicionar
+      containers:
+      - name: server
+        lifecycle:
+          preStop:
+            exec:
+              command: ["/bin/sh", "-c", "sleep 5"]  # Dar tempo para conexões fecharem
+```

+
+## Checklist de Implementação
+
+### Prioridade ALTA (Segurança)
+- [ ] Adicionar usuário non-root em todos os Dockerfiles
+- [ ] Adicionar `USER appuser` antes do CMD
+- [ ] Configurar `securityContext` nos deployments K8s
+- [ ] Remover todos os HEALTHCHECKs dos Dockerfiles
+
+### Prioridade ALTA (Confiabilidade)
+- [ ] Corrigir CMD para exec form com propagação de sinais
+- [ ] Adicionar `terminationGracePeriodSeconds` nos deployments
+- [ ] Testar rolling updates funcionam corretamente
+
+### Prioridade MÉDIA (Otimização)
+- [ ] Otimizar ordem de COPY para melhor cache
+- [ ] Limpar cache pip/uv após instalações
+- [ ] Remover `tests/` do build de produção (se não necessário)
+
+### Prioridade BAIXA (Melhoria Contínua)
+- [ ] Considerar distroless images para mais segurança
+- [ ] Implementar multi-arch builds (amd64/arm64)
+- [ ] Adicionar SBOM (Software Bill of Materials)
+
+## Testes Recomendados
+
+```bash
+# Testar se containers rodam como non-root
+docker run --rm your-image id
+# Deve retornar: uid=1001(appuser) gid=1001(appuser)
+
+# Testar graceful shutdown
+docker run -d --name test your-image
+docker stop test  # Deve parar em ~2-3 segundos, não 10
+
+# Testar no K8s
+kubectl rollout restart deployment/archon-server -n archon
+kubectl rollout status deployment/archon-server -n archon
+# Deve ser smooth sem downtime
+```

+# Docker vs Kubernetes Build Strategy
+
+## Overview
+
+O projeto Archon agora mantém **duas versões de imagens Docker** para cada serviço:
+
+1. **Docker Version** - Imagens originais para uso com Docker Compose
+2. **Kubernetes Version** - Imagens otimizadas para produção em Kubernetes
+
+## Arquivos Dockerfile
+
+### Docker Compose (Original)
+- `python/Dockerfile.server` → `server:latest`, `server:docker-latest`
+- `python/Dockerfile.mcp` → `mcp:latest`, `mcp:docker-latest`
+- `python/Dockerfile.agents` → `agents:latest`, `agents:docker-latest`
+- `archon-ui-main/Dockerfile.production` → `frontend:latest`, `frontend:docker-latest`
+
+### Kubernetes (Optimized)
+- `python/Dockerfile.k8s.server` → `server:k8s-latest`
+- `python/Dockerfile.k8s.mcp` → `mcp:k8s-latest`
+- `python/Dockerfile.k8s.agents` → `agents:k8s-latest`
+- `archon-ui-main/Dockerfile.k8s.production` → `frontend:k8s-latest`
+
+## Image Tags
+
+### Docker Version Tags
+```bash
+git.automatizase.com.br/luis.erlacher/archon/server:latest
+git.automatizase.com.br/luis.erlacher/archon/server:docker-latest
+git.automatizase.com.br/luis.erlacher/archon/server:docker-{commit-sha}
+
+# Mesma estrutura para: mcp, agents, frontend
+```
+
+### Kubernetes Version Tags
+```bash
+git.automatizase.com.br/luis.erlacher/archon/server:k8s-latest
+git.automatizase.com.br/luis.erlacher/archon/server:k8s-{commit-sha}
+
+# Mesma estrutura para: mcp, agents, frontend
+```
+
+## Diferenças Entre as Versões
+
+### Docker Version (Original)
+- ✅ Compatível com Docker Compose
+- ✅ Roda como root (compatibilidade)
+- ✅ Inclui HEALTHCHECK no Dockerfile
+- ✅ Estrutura simplificada para desenvolvimento local
+
+### Kubernetes Version (Optimized)
+- ✅ **Non-root user** (UID/GID 1001) - Segurança
+- ✅ **Proper signal propagation** - Graceful shutdown em rolling updates
+- ✅ **No HEALTHCHECK** - K8s usa liveness/readiness probes
+- ✅ **Cache cleanup** - Imagens menores (remove ~/.cache/pip, ~/.cache/uv)
+- ✅ **Production-only** - Não inclui `tests/` directory
+- ✅ **Optimized layers** - Melhor aproveitamento de cache
+
+## Otimizações Kubernetes
+
+### 1. Non-Root User
+```dockerfile
+# Cria usuário e grupo com IDs fixos
+RUN groupadd -r appuser -g 1001 && \
+    useradd -r -g appuser -u 1001 appuser && \
+    chown -R appuser:appuser /app
+
+USER appuser
+```
+
+**Benefícios:**
+- Segurança: Reduz risco de container escape
+- Compliance: Atende policies de segurança K8s (PodSecurityStandards)
+- Best Practice: Recomendado pela OWASP e CIS Benchmarks
+
+### 2. Signal Propagation
+```dockerfile
+# ✅ CORRETO - Propagation com exec
+CMD ["sh", "-c", "exec python -m uvicorn ..."]
+
+# ❌ INCORRETO - Shell não propaga sinais
+CMD sh -c "python -m uvicorn ..."
+```
+
+**Benefícios:**
+- Graceful shutdown: SIGTERM chega ao processo Python
+- Zero downtime: Rolling updates funcionam corretamente
+- Connection draining: Conexões fecham gracefully
+
+### 3. No HEALTHCHECK
+```dockerfile
+# Docker version tem:
+HEALTHCHECK --interval=30s CMD ...
+
+# K8s version NÃO tem (redundante)
+# K8s já define em livenessProbe/readinessProbe
+```
+
+**Benefícios:**
+- Menor tamanho de imagem
+- Menos processos rodando no container
+- Health checks gerenciados pelo K8s (mais flexível)
+
+### 4. Cache Cleanup
+```dockerfile
+RUN uv pip install --system --group mcp && \
+    rm -rf ~/.cache/uv ~/.cache/pip
+```
+
+**Benefícios:**
+- Imagens 10-15% menores
+- Menos I/O no registry
+- Pull mais rápido nos nodes K8s
+
+## Como Usar
+
+### Para Docker Compose (Desenvolvimento Local)
+```yaml
+# docker-compose.yml
+services:
+  archon-server:
+    image: git.automatizase.com.br/luis.erlacher/archon/server:latest
+    # ou
+    image: git.automatizase.com.br/luis.erlacher/archon/server:docker-latest
+```
+
+### Para Kubernetes (Produção)
+```yaml
+# k8s-manifests.yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: archon-server
+spec:
+  template:
+    spec:
+      securityContext:
+        runAsNonRoot: true
+        runAsUser: 1001
+        runAsGroup: 1001
+        fsGroup: 1001
+      containers:
+      - name: server
+        image: git.automatizase.com.br/luis.erlacher/archon/server:k8s-latest
+        securityContext:
+          allowPrivilegeEscalation: false
+          capabilities:
+            drop:
+              - ALL
+```
+
+## CI/CD Workflow
+
+O workflow `.gitea/workflows/build-images.yml` constrói ambas as versões automaticamente:
+
+### Trigger
+- Push para branch `main`
+- Workflow manual dispatch
+
+### Jobs Executados
+
+**Docker Version (4 jobs):**
+- `build-server-docker`
+- `build-mcp-docker`
+- `build-agents-docker`
+- `build-frontend-docker`
+
+**Kubernetes Version (4 jobs):**
+- `build-server-k8s`
+- `build-mcp-k8s`
+- `build-agents-k8s`
+- `build-frontend-k8s`
+
+**Total:** 8 jobs paralelos (quando possível)
+
+## Atualizar Manifests Kubernetes
+
+Para usar as imagens K8s otimizadas, atualize `k8s-manifests-complete.yaml`:
+
+```yaml
+# ANTES (versão Docker)
+image: git.automatizase.com.br/luis.erlacher/archon/server:latest
+
+# DEPOIS (versão K8s)
+image: git.automatizase.com.br/luis.erlacher/archon/server:k8s-latest
+```
+
+Faça isso para todos os deployments:
+- archon-server
+- archon-mcp
+- archon-agents
+- archon-frontend
+
+## Tamanhos das Imagens
+
+### Estimativa de Redução (K8s vs Docker)
+
+| Service | Docker | K8s | Redução |
+|---------|--------|-----|---------|
+| Server  | ~1.2GB | ~1.1GB | ~8% |
+| MCP     | ~450MB | ~420MB | ~7% |
+| Agents  | ~480MB | ~450MB | ~6% |
+| Frontend| ~50MB  | ~48MB  | ~4% |
+
+**Economia total:** ~100MB por deploy completo
+
+## Testes
+
+### Verificar Non-Root
+```bash
+# Docker
+docker run --rm git.automatizase.com.br/luis.erlacher/archon/server:k8s-latest id
+# Esperado: uid=1001(appuser) gid=1001(appuser)
+
+# Kubernetes
+kubectl exec -it deployment/archon-server -n archon -- id
+# Esperado: uid=1001(appuser) gid=1001(appuser)
+```
+
+### Testar Graceful Shutdown
+```bash
+# Docker
+docker run -d --name test git.automatizase.com.br/luis.erlacher/archon/server:k8s-latest
+docker stop test  # Deve parar em ~2-3 segundos
+
+# Kubernetes
+kubectl rollout restart deployment/archon-server -n archon
+kubectl rollout status deployment/archon-server -n archon
+# Deve ser smooth, sem downtime
+```
+
+### Verificar Tamanho das Imagens
+```bash
+docker images | grep archon
+# Compare tags 'latest' vs 'k8s-latest'
+```
+
+## Migration Checklist
+
+Se você está migrando de Docker para K8s:
+
+- [ ] Pull das novas imagens K8s
+- [ ] Atualizar manifests K8s para usar `:k8s-latest`
+- [ ] Adicionar `securityContext` nos deployments (veja exemplo acima)
+- [ ] Adicionar `terminationGracePeriodSeconds: 30`
+- [ ] Remover HEALTHCHECKs se você tinha configurado manualmente
+- [ ] Testar rolling updates funcionam corretamente
+- [ ] Verificar logs não mostram permission errors
+
+## Manutenção
+
+### Quando Modificar Dockerfiles
+
+**Docker Version (Original):**
+- Modificar apenas para compatibilidade com Docker Compose
+- Manter simples e focado em desenvolvimento local
+
+**Kubernetes Version (Optimized):**
+- Aplicar todas as otimizações de produção
+- Seguir best practices de segurança
+- Manter alinhado com Docker version (funcionalidades)
+
+### Sincronização
+
+As duas versões devem ter as **mesmas funcionalidades**, apenas diferindo em:
+- User (root vs non-root)
+- Signal propagation (CMD format)
+- Health checks (Dockerfile vs K8s)
+- Optimizations (cache cleanup, layer ordering)
+
+## Troubleshooting
+
+### Erro: Permission Denied no K8s
+```
+Error: EACCES: permission denied, open '/app/file'
+```
+
+**Solução:** Verifique se todos os arquivos foram copiados com `--chown=appuser:appuser`
+
+### Erro: Rolling Update com Downtime
+```
+502 Bad Gateway durante deploy
+```
+
+**Solução:** Verifique se CMD usa exec form para propagação de sinais
+
+### Erro: Imagem Pull Failed
+```
+ImagePullBackOff
+```
+
+**Solução:** Verifique se as imagens K8s foram construídas e pushed:
+```bash
+# No servidor Gitea Actions
+docker images | grep k8s-latest
+```
