我在AWS上构建了一个Debian 11 EC2，并在上面安装了postgres 14.5，在上面添加了docker和docker compose；admin'使用密码。我创建了docker-compose.yml文件和.env文件。
当我尝试使用docker-compose.yml文件时，我得到：
sudo docker compose up -d
services.database.environment must be a mapping
当我用构建码头集装箱时
sudo docker build . -t tvappbuilder:latest
然后尝试使用运行
sudo docker run -p 8080:8080 tvappbuilder:latest --env-file .env -it
Config Path .

4:47PM FTL server/cmd/video_conferencing/server.go:71 > Error initializing database error="pq: Could not detect default username. Please provide one explicitly"
以下是迄今为止的码头工人：

这是docker-compose.yml:

这是Dockerfile:

据此：https://pkg.go.dev/github.com/lib/pq我可能不需要使用pq，而是直接使用postgres，但它似乎是这样设置的。
非常感谢你的指点！
根据注释，您的设置存在许多问题。
第一个是运行docker compose up -d时出现错误services.database.environment must be a mapping。这是由docker-compose.yml中类似- APP_ID: $APP_ID的行引起的-根据文档使用APP_ID: $APP_ID或- APP_ID=$APP_ID。
另一个问题是，您在裸操作系统上安装了Postgres，然后使用了Postgres容器。你只需要做一个或另一个(但如果使用docker，你会想使用Postgres数据的卷或装载(否则，当容器重建时，它会丢失(。
可能还有其他问题，但以上内容应该会让您开始。
