nginx 不使用 VSCode 远程容器扩展（docker compose）打开本地主机

Question

localhost 无法从主机浏览器中使用 Visual Studio 代码的远程容器扩展打开。

如果从 VSCode Command Remote-Containers: Reopen in Container并从浏览器打开http://localhost ，将显示502 Bad Gateway 。

但是，如果直接从主机执行命令，Laravel 顶部屏幕将在http://localhost/处打开。

是否缺少远程容器设置？

通过更改此文件解决了它。

.devcontainer/docker-compose.yml注释掉是command: ...

    # Overrides default command so things don't shut down after the process ends.
    # command: /bin/sh -c "while sleep 1000; do :; done"
