背景
由于国内网络环境的特殊性，使用 docker build 命令构建镜像成为了一件相当困难的事情。尤其是较大的镜像，即使已经配置了代理，仍然极易失败。我已经厌倦了反复处理这类问题，因此想到可以借助 GitHub Actions，让 GitHub 自动帮我们完成镜像的构建。虽然我此前也没有深入使用过 GitHub Actions，但得益于像 Claude Code 和 github-cli 这样的工具，我们完全可以轻松实现这一目标。
前置准备
- 安装Claude Code
- 安装并配置了github-cli
提示词
ultrathink 使用github-cli工具为我建立一个docker-builder仓库，这是对 docker-builder 仓库功能的一个简单、精炼的描述：
""""
docker-builder 仓库是一个中央化的、按需服务的 Docker 镜像构建中心。
它本身不包含任何具体的应用代码，其核心功能是提供一个通用的 GitHub Actions 工作流程，让你可以：
1.手动触发：通过在 GitHub 页面的表单中填写参数，来启动一个构建任务。
2.构建任何仓库：指定任何你有权访问的 GitHub 仓库地址、代码分支或标签。
3.灵活配置：定义要使用的 Dockerfile 路径和最终生成的镜像名称。
4.统一输出：将构建好的镜像自动推送到统一的 GitHub 容器镜像仓库 (GHCR) 中。
""""
下面是github-cli的使用文档:

"""剩下的工作交给Claude Code即可，在我的电脑上，Claude Code 一次性地、没有任何报错地完成了这个功能！
效果展示
只要手动填入这些参数即可：
成功构建了镜像：
拉取镜像
# 直接拉取
docker pull ghcr.io/kuhbz/iris:latest
# 使用南京大学镜像加速（推荐）
docker pull ghcr.nju.edu.cn/kuhbz/iris:latest
