it is because you need to set some variables if you use docker compose file
my worked solution is under
  ### ===================
  ### ZOOKEEPER SERVICE
  ### ===================
  zookeeper:
    image: confluentinc/cp-zookeeper:latest
    restart: always
    healthcheck:
      interval: 120ms
      retries: 5
      start_period: 60ms
      test: |
        touch /tmp/healthcheck.txt &&
        mkdir /tmp/healthcheck &&
        mv /tmp/healthcheck.txt /tmp/healthcheck &&
        cd /tmp/healthcheck &&
        echo "hello my docker container is working fine" >> healthcheck.txt &&
        cat healthcheck.txt &&
        sleep 3 &&
        rm "${PWD}/healthcheck.txt" &&
        cd .. &&
        sleep 3 &&
        rmdir "${PWD}/healthcheck" &&
        clear
      timeout: 30ms
    environment:
      ZOOKEEPER_SERVER_ID: 1
