如何对 db2 容器进行适当的健康检查，以便我的应用程序容器可以安全启动？

Question

目前我只是在等待一个比较安全的时间框架，然后在这个 docker-compose 文件中启动应用程序容器：

# this compose spins up a db2 database for development purposes
version: "3"
services:
  db2: # https://hub.docker.com/r/ibmcom/db2
    #    image: ibmcom/db2:11.5.8.0
    image: icr.io/db2_community/db2:11.5.8.0
    privileged: true
    expose:
      - 50000
    ports:
      - "50000:50000"
    environment:
      LICENSE: accept
      DBNAME: sample
      DB2INSTANCE: db2inst1
      DB2INST1_PASSWORD: change-me-please
    healthcheck:
      # TODO find a real health check for db2
      test: [ "CMD", "sleep", "300"]
      interval: 30s
      timeout: 301s
      retries: 3
  app:
    build:
      context: ../../
      dockerfile: ./src/infrastructure/Dockerfile
    expose:
      - 7070
    ports:
      - "7071:7070"
    environment:
      APP_PROFILE: compose
    depends_on:
      db2:
        condition: service_healthy
    restart: on-failure

是否有任何特定于 db2 的工具能够为我提供更好的健康检查？ 欢迎任何指导。 对于上下文，整个项目是here.
