刚启动容器时，如何运行Echo Hello World

Question

我有一个如下：

FROM kong
USER 0

RUN mkdir -p /kong/declarative/
COPY declarative/kong.yml /kong/declarative/

# COPY docker-entrypoint.sh /docker-entrypoint.sh
# RUN ["chmod", "+x", "/docker-entrypoint.sh"]
# ENTRYPOINT ["/docker-entrypoint.sh"]


RUN cp /etc/kong/kong.conf.default /etc/kong/kong.conf

docker-entrypoint.sh

#!/usr/bin/env bash

echo "Hello World"

我也有一个docker-compose文件。

version: "3.8"

networks:
 kong-net:
  name: kong-net
  driver: bridge
  ipam:
    config:
      - subnet: 172.1.1.0/24

services:
  kong:
    container_name: kong
    build:
      context: .
      dockerfile: Dockerfile
    restart: unless-stopped
    networks:
      kong-net:
        ipv4_address: 172.1.1.40
    healthcheck:
      test: [ “CMD”, “curl”, “-f”, “http://kong:8000” ]
      interval: 5s
      timeout: 2s
      retries: 15
    environment:
      - KONG_DATABASE=off
      - KONG_ADMIN_LISTEN=0.0.0.0:8001, 0.0.0.0:8444 ssl
      - KONG_PROXY_ACCESS_LOG=/dev/stdout
      - KONG_ADMIN_ACCESS_LOG=/dev/stdout
      - KONG_PROXY_ERROR_LOG=/dev/stderr
      - KONG_ADMIN_ERROR_LOG=/dev/stderr
      - KONG_DECLARATIVE_CONFIG=/kong/declarative/kong.yml
      - MYNAME=amin
    ports:
      - "8444:8444"
      - "80:8000"
      - "443:8443"
      - "8001:8001"

我还有一个docker-compose文件，如下面，当我运行docker-composes-build时， 它按预期运行良好，但是如果我输入docker-file 中的三行和运行docker-compose-build这是结果

我做错了什么？我应该如何解决？ 在启动之前，我需要在运行阶段的Docker容器中运行一个命令。我应该怎么做？
