我对 docker 很陌生，并且花了很多时间试图解决这个问题。我无法将我的 aspnetcore react docker 映像部署到 docker。我已经成功部署了许多 aspnetcore 映像，但是当涉及到 SPA 时，我似乎无法弄清楚。我开始了一个新的 .net5 react 项目来测试 docker 文件。我为构建创建了一个 docker-compose 文件。每次我收到以下错误。任何帮助将不胜感激。
该项目称为 dockerSPA - 我专门为测试目的创建了它。请让我知道我是否可以提供其他信息来解决此问题

编辑
通过遵循微软的旧 .net3 建议并进行一些小更新，我终于设法通过安装 nodejs 来部署 react spa 客户端。现在我的 nodejs 服务立即退出，代码为 0；

有些东西告诉我我需要设置 redis 来处理这些问题，但我可能是错的。
