1. 基础环境配置

  [Ubuntu 22.04] 安装K8S基础环境准备脚本

2. Docker安装

  [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：192.168.11.20，即可访问刚才部署的harbor

4. 部署ContainerD

  [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horbor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": ["","","","","","",""],"insecure-registries": ["192.168.11.20:80"]
}
EOFsystemctl restart docker.service

  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
