shell一键部署harbor脚本

#!/bin/bash
# ----------------------------------------------------------------------------
# 作者: 李毓
# 版本: 1.0.0
# 创建日期: 2024-05-29
# 更新日期: 2024-05-29
# 简介: 因为外出部署经常涉及到做离线安装包，部署一个干净的harobr比较麻烦。所以写了一个部署harbor的脚本。为了贴合现场环境，和网上其他的部署版本不同的是增加了ssl证书的配置。稍加改动甚至可以在wsl部署，不占用服务器资源。这个harbor的脚本，运行环境为ubuntu20.04开发，但是其他ubuntu环境也能用，其中必须修改选项为变量中的harbor_ip地址。其余酌情修改。另外脚本中下载的docker-compose和离线harbor包自己准备。我这里是内网下载的。
