1. 🛠️ 基础环境配置
📌 安装基础环境请参考：[Ubuntu 22.04] 安装K8S基础环境准备脚本
2. 🐳 Docker 安装
📌 docker安装请参考：[Ubuntu 22.04] 安装docker，并设置镜像加速
3. 🚢 部署 Harbor，HTTP 访问
📌 [Ubuntu 22.04] 安装Harbor#HTTP方式
🔍 浏览器中输入：http://192.168.11.20，即可访问刚才部署的harbor
4. 📦 部署 ContainerD
📌 containerd的安装请参考：[Ubuntu 22.04] 安装containerd
5. 🔄 修改 docker 配置文件，向 harbor 中推入镜像
🎯 目标：向第三步部署的 harbor 仓库中推入镜像仓库
根据目前的环境，有两种方式可以向harbor中推入镜像。其一是通过docker向harbor中推入镜像仓库。其二是通过containerd向harbor中推入镜像
由于目前我们对于containerd并不熟悉，因此我们先直接通过docker向harbor中推入镜像，由于我们自己搭建的harbor是私有仓库，并且是HTTP的方式，因此我们需要配置docker的配置文件。
你可以重新找一台机器安装docker做实验，或者直接使用harbor那台机器也可以，这里我直接使用harbor那台机器上的docker工具，向harbor推送镜像。
配置修改如下，主要是增加了insecure-registries配置，如果你的配置文件中包含其它的配置，请不要直接执行，否则会覆盖你的配置。；另外，请一定要注意 80 端口，这个不能省略，否则docker会以https的方式访问harbor
tee /etc/docker/daemon.json << 'EOF'{ "registry-mirrors": [ "http://hub-mirror.c.163.com", "https://mirror.baidubce.com", "https://docker.mirrors.ustc.edu.cn", "https://registry.docker-cn.com", "https://dockerproxy.com", "https://ccr.ccs.tencentyun.com", "https://registry.cn-hangzhou.aliyuncs.com" ], "insecure-registries": ["192.168.11.20:80"]}EOF
systemctl restart docker.service
复制代码
这里我随便推送harbor的一个镜像到我自己的harbor仓库当中，操作如下，第一步：重新打 tag， 第二步：docker push。这里需要注意的是，再推送镜像之前，一定要在登录harbor，提前建立仓库目录，否则推送会被拒绝，另外，静态的 Tag 所指向的仓库端口必须要显式指定 80 端口，否则默认使用 443 端口
