Conéctate desde Google Kubernetes Engine con un proxy de sidecar

En este manifiesto, se define una implementación de Kubernetes que ejecuta el proxy de autenticación como un contenedor sidecar junto con tu aplicación. Usa este patrón para proporcionar conexiones seguras, autorizadas y encriptadas desde tu aplicación en Google Kubernetes Engine a tu instancia de base de datos.
