nginx 不使用 VSCode 远程容器扩展（docker compose）打开 localhost答案

【问题标题】：nginx does not open localhost with VSCode Remote Containers Extension (docker compose)nginx 不使用 VSCode 远程容器扩展（docker compose）打开 localhost
【发布时间】：2019-12-17 06:04:21
【问题描述】：

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

如果从VSCode命令Remote-Containers: Reopen in Container展开，在浏览器中打开http://localhost，会显示502 Bad Gateway。

但是，如果你直接从主机执行命令，Laravel 顶部屏幕将打开http://localhost/。

是否缺少远程容器设置？

【解决方案1】：

通过修改这个文件解决了。

.devcontainer/docker-compose.yml 注释掉的是command: ...

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