feat: add docker deployment support

[AprilNEA]

使用 Docker 构建本项目

Todo

• 添加 README.md 说明
• 发布 Docker 镜像
• 分阶段构建减小镜像体积

[vercel]

Someone is attempting to deploy a commit to a Personal Account owned by @Yidadaa on Vercel.

@Yidadaa first needs to authorize it.

[x-dr]

分阶段构建减小镜像体积可以参考官方例子next.js example

• 先在next.config.js 添加一行output: 'standalone'指定了构建输出的形式

const nextConfig = {
  experimental: {
    appDir: true,
  },
  output: 'standalone',
  webpack(config) {
    config.module.rules.push({
      test: /\.svg$/,
      use: ["@svgr/webpack"],
    }); // 针对 SVG 的处理规则

    return config;
  }
};

USER nextjs

EXPOSE 3000

ENV PORT 3000

CMD ["node", "server.js"]

构建运行

docker build -t nextjs-docker .
docker run -p 3000:3000 nextjs-docker

尝试了，但出现构建错误，对于使用了appDir实验性功能的Nextjs，该 Dockerfile可能不适用

[AprilNEA]

Docker 镜像已发布，docker pull aprilnea/chatgpt-next-web

[Yidadaa]

感谢，我今晚验证后会合并此 PR。

应该是缺少git

你应该自己发布 Docker 镜像来保证自动推送的可控性

[Yidadaa]

@Chanzhaoyu 我会引入一个 github action 来自动发布。
