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

syntax

    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:8080/health"]
      interval: 1m30s
      timeout: 30s
      retries: 3
      start_period: 5s

health check
# test => berisikan cara melakukan test health check
# interval
# timeout
# retries => total retry
# start_period => waktu mulai
