Opcional, se você precisar alterar as imagens do aplicativo:

• (opcional) construir imagens docker:
  • cd protected-service; docker build -t protected-service:0.0.1 .
  • cd public-service; docker build -t public-service:0.0.1 .
• (opcional) enviar imagens docker para o minikube:
  • minikube image load protected-service:0.0.1
  • minikube image load public-service:0.0.1
