3 传统.NET 4.x应用容器化

文章插图
| 总结/Edison Zhou
上一篇我们自己通过编写Dockerfile来编译部署一个ASP.NET MVC应用程序到Windows Container，这一篇我们来试着将.NET 4.x的镜像推送到harbor私有镜像仓库 。
1 准备工作
假设有两台服务器，这里我使用的是阿里云ECS：
Node1：Windows Server 2019，Docker Client
Node2：CentOS 7.5，Harbor
其中，Node1作为客户端，主要用来推送镜像到harbor镜像仓库 和 从harbor拉取镜像运行容器实例 。Node2作为服务端，主要用来运行harbor镜像仓库对企业内部提供容器镜像服务 。
2 搭建Harbor镜像仓库
Why Harbor?
因为Harbor是目前最流行的企业级私有容器镜像仓库之一，而且它同时支持Linux Container 和 Windows Container 的镜像，使得它比较符合我的需求 。
快速搭建过程
我们在Node2（CentOS）上来快速地基于Harbor搭建一个私有镜像仓库 。
step1.安装docker compose
# curl -L https://github.com/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose# chmod +x /usr/local/bin/docker-compose# docker-compose -versionstep2.下载并解压harbor离线安装包
# wget https://github.com/vmware/harbor/releases/download/v1.10.1/harbor-offline-installer-v1.10.1.tgz# tar xvf harbor-offline-installer-v1.10.1.tgzstep3.修改harbor.yml配置，主要修改hostname 和 admin初始密码，注释掉https的配置（生产环境建议开启https，这里只做快速演示） 。
# Configuration file of Harbor# The IP address or hostname to access admin UI and registry service.# DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.hostname: 47.108.111.236# http related confighttp:# port for http, default is 80.
