StatefulSet Banco de Dados

Para o banco de dados, a versão preliminar seria um PostgreSQL. Recomendamos um serviço gerenciado de banco de dados. Se necessário por economia ou para disponibilizar um ambiente menor para treinamento ou homologação do sistema, pode-se instalar um banco de dados diretamente no cluster. Segue um exemplo do yaml para isso.

apiVersion: apps/v1
kind: StatefulSet

  name: db
spec:
  serviceName: "db"
  replicas: 1
