health check

• docker health check => secara default container yang dibuat, baik itu secara manual ataupun menggunakan docker compose
  • pasti akan selalu menggunakan health check yang dibuat di docker file
  • namun, jika kita ingin mengubah health check tersebut, itu juga bisa dilakukan
  • kita bisa ubah di file konfigurasi docker compose pada attribute healthcheck di service
