我的docker compose文件似乎运行良好,并且在docker仪表板中,我看到适当的容器正在工作。当我转到http:// localhost:8080 /时,我看到的是一条错误消息,内容为:“此页面无效。本地主机未发送任何数据。 ERR_EMPTY_RESPONSE”。我不确定该如何解决。我看到某个地方用'0.0.0.0'替换了localhost,但是我不确定在这种情况下该怎么做,而且我觉得我已经看到它可以与localhost一起工作,所以我不确定该如何处理这些信息。我检查了其他来源,看看我做错了什么,没有找到好的解决方案。我很乐意就此事寻求任何建议!

您打开和发布的端口不匹配。您需要在docker-compose.yml
中修复.services.dev.ports.[0]
,(用Node将第二个端口更改为内部打开的端口):
version: '3'
services:
dev:
image: filamentgraphql/filament-dev
container_name: 'filament-dev-hot'
ports:
# Fix port here
